The Back Ends of a pair of lanes are shipped two to a pallet. The ancillary equipment, Pin Distributor, Ball Accelerator, Sweep Assemblies, Back End motors with brackets and hardware are shipped in wooden packing cases. Handling of Pallets. The pallets are made from wood with access for a Fork Lift or a pallet truck. Figure 3- shows the pallet used for Front End and Back End units. The forks of the fork lift or the pallet truck must be in the centre of the pallet prior to lifting to ensure an even distribution of weight. The opening of the forks on the Fork Lift should be as wide as possible. Handling of Packing Cases. The packing cases can be lifted and moved using a Fork Lift truck, or a pallet truck. Care must be taken to ensure that the centre of gravity of the packing cases is as close as possible to the centre of the forks of either the pallet truck or Fork Lift truck. General It is important that during, and following, the movement of heavy machinery that no pieces of the packaging be abandoned in or around the work area. ( screws, nuts, bolts, polythene sheeting etc.) The disposal of any discarded waste material should be carried out according to local regulations. Fig. 3- Handling of pallets page 4/2 Chapter 3 - Transport - Handling - Storage

35 IMPORTANT- Check that any tools and equipment used (hooks, shackles, chains, and strops) can support the weight of the equipment being handled.! IMPORTANT- The equipment should normally only be handled using Fork Lift or manual pallet trucks. If a crane has to be used to raise equipment still on the pallets, it is important that the chains, strops, or cables be spread out above the height of the machines to avoid damage. IMPORTANT- When pallets of machines are being split into component parts, attention should be paid at all times to ensure that no-one is in the range of operation of any of the machines used for this operation (cranes, fork lift trucks etc.) List of component parts as shipped by the manufacturer The most efficient means of packaging the ST pinspotter for shipment is as follows: Front End: Two front ends of a pair of lanes are shipped together on one specially constructed wooden pallet. Back End: As above, two back ends of a pair of adjacent lanes are shipped together on one specially constructed wooden pallet. Ancillary components.

Figure 3-2 indicates how the pallets should be lifted. Fig. 3-2 Lifting pallets using fork lift truck By means of a crane using either Strops, ropes or cables. The pallets may have to be raised, eg, to an upper floor, so a crane may have to be used. The ropes, strops or cables should be passed through the base of the pallets as shown in Figure 3-3 below. All lifting strops, ropes, etc. should be checked for damage prior to any lifting being carried out. Materials used should have a minimum lifting capacity of 3 tonnes. The Length of the ropes, strops, cables used should be such that the hook of the crane is at least B x the length of one side of the pallet above the pallet (see Figure 3-3 B). A B! page 6/2 Fig. 3-3 Lifting pallets using ropes, cables, etc. Danger- Do not stand below pallets at any time when lifting is in progress!! Chapter 3 - Transport - Handling - Storage

37 3.4 Machine handling - removal from pallets The parts of the Pinspotters requiring handling by mechanised transport are: Front Ends; Back Ends; Accelerator (in wooden crate); Various wooden crates. The parts listed above are to be handled and transported by attaching the lifting equipment at the points indicated. Where possible, lifting aids have been provided. The lifting and handling operations are to be carried out by using the lifting lugs provided at the points indicated Front Ends Characteristics of Front End Weight: 450 kg Length: 50 cm Width: 55 cm Height: 65 cm! Attention- At no time should any person stand or pass below any equipment whilst it is suspended by any crane or fork lift truck. The Front Ends of the ST pinspotters are packaged on a pallet in pairs (see figure 3-4). The two parts of the pinspotters must be separated using a Fork Lift Truck and a special attachment for the purpose. The system is illustrated in Figure 3-4. Chapter 3 - Transport - Handling - Storage Fig. 3-4 Machine handling - Front Ends page 7/2 SWITCH ENTERTAINMENT S.A.

38 User s manual Special brackets are fixed to the frames (point A ) of the first machine to be removed as seen in Figure 3-5.These brackets ensure that the lifting tackle is attached to the centre of gravity of each machine. A further rope or cable is then attached to (point B ) as shown in Figure 3-5. When the Fork Lift is completely supporting the weight of the machine, the bolts holding the machines together can then be removed. The other machine remains connected to the steel angle irons that are fixed to the pallet, and so can not fall. Point A Point B Point A Fig. 3-5 Special brackets When the fork lift has raised the machine at least 50 cm, the fork lift can now move slowly back and away from the pallet, maintaining the pinspotter in the vertical position by keeping tension on the rope attached to point B. The next operation is to bring the pinspotter into the horizontal position by slowly releasing the tension on the rope fixed to point B (see Figure 3-5). The Front End is now lowered onto the special fixture on a pallet truck and is taken to the support structure (kickback), where it is secured by four studs. The remaining pinspotter on the pallet is handled in exactly the same way as the first one. Fig. 3-6 Support structure (kickback) page 8/2 Chapter 3 - Transport - Handling - Storage

39 3.4.2 Back Ends Characteristics of Back End Weight: 465 kg Length: 25 cm Width: 55 cm Height: 65 cm! Danger- Do not stand below pallets at any time when lifting is in progress!!! All handling of equipment should be done using the lifting points and special fixtures The Back Ends are also packaged in one pair to a pallet (see Figure 3-7).The two parts are separated using the same special fixture on the Fork lift truck as in paragraph Two special brackets are then inserted into the holes in the side frames of the Back Ends, which coincide with the centre of gravity. The strops which are hanging from the fixture on the Fork lift truck are then attached to the two fixtures on the side frames of the pinspotters (see Figure 3-8), using shackles. The machine is then slowly raised until it is completely clear of the other machine which will remain on the pallet. The Fork lift can then move slowly backwards until it is completely clear of the pallet. The machine can then be turned around until the four adjustable feet are pointing towards the ground. The machine can now be lowered until the feet are just clear of the ground,and may be transported to a point as close to the final destination as possible in this way. Fig. 3-7 Machine handling - Back Ends Chapter 3 - Transport - Handling - Storage page 9/2 SWITCH ENTERTAINMENT S.A.

40 User s manual Before the machine is completely lowered, the four jacking screws should be made as long as possible to give enough clearance from the ground so that the forks of the manual pallet truck can easily fit under the frame. The machine should then be picked up with a pallet truck and manoeuvred into position behind the Front End (see Figure 3-8) Accelerator Characteristics of Accelerator packing case Weight: 250 kg Length: 25 cm Width: 35 cm Height: 00 cm Fig. 3-8 Machine handling - Back Ends The forks of the pallet truck should be located in the centre of the Back End, approaching from the rear. The accelerator assembly is shipped in a single wooden packing case. The packing case can be handled either by a Fork Lift truck or a manual pallet truck. It is advisable to transport more than one packing case at a time to reduce the risk of the case tipping over when it is moved. The packing cases should be tied together to further reduce the risk of falling over when moved. page 0/2 Chapter 3 - Transport - Handling - Storage

41 3.4.4 Other packing cases The other packing cases that complete the shipment contain the smaller component parts of the ST pinspotter and can be easily moved using a manual pallet truck.

Particular care and attention is required when the pinspotters are being disassembled from the pallets, and subsequently suspended from a crane or fork lift truck. Care must also be taken when the single pinspotters are being transported, and positioned, using a manual pallet truck with the special fixture designed for the purpose. Technicians carrying out the operations above should be constantly aware of the potential dangers of injury by abrasion, or even cutting, by unprotected sharp edges. Special care should be taken to ensure that the pinspotter is not exposed to the risk of overbalancing whilst being manoeuvred on the manual pallet truck. No fewer than three persons should be employed for this operation, and the speed at which the pallet truck is moved should be kept to a safe minimum. The cabling and wiring of the ST pinspotter should only be carried out by SWITCH-trained personnel, using the appropriate schematic drawings supplied for the purpose. Internal cabling and wiring should only be carried out with the main power supply cable disconnected from the mains supply. SWITCH-trained technicians will always be present for the first installation of the equipment, and will supervise and train the future users in the operation of the pinspotter. SWITCH will make training courses available to all potential operators of their equipment. SWITCH reserve the right to include the successful completion of such a course as a condition to any warranty agreement. When the installation and handover of the equipment have been completed, this manual will be the reference point for all the information required to ensure trouble-free operation of the ST pinspotter. 4.. General installation guidelines - Machine condition: Unassembled, isolated from mains power supply. - Number of installation crew: Minimum 3 persons - Qualifications of crew: Switch-trained supervisor; Maintenance technicians (2). Chapter 4 - Installation page 3/6 SWITCH ENTERTAINMENT S.A.

46 User s manual 4.2 Ambient conditions Switch recommends the following ambient conditions for the optimum operation of the ST pinspotter: - Temperature: +0 C to +35 C. - Relative humidity: 35% to 70% RH. SWITCH SA should be made aware of operating conditions that do not fall within the above temperature and humidity ranges. It is also recommended that the operating temperature and humidity values be constant, and not be subject to sudden periodic changes. 4.3 Installation and operational dimensions The SWITCH ST pinspotter has been designed to operate on Tenpin Bowling lanes constructed to USBC/FIQ approved dimensions. These dimensions must be respected to ensure correct installation and operation of the equipment. Additional considerations: Installations supplied with SWITCH Horizontal Ball Exit : A corridor of at least 25 cm in width must be available to the rear of the pinspotters to allow for the removal of the SWITCH horizontal ball exit assembly. Installations supplied with SWITCH Positive Ball Exit : Switch positive ball exits are supplied when the 25 cm minimum corridor width cannot be respected (or as a preferred equipment option). In this case, SWITCH recommends a minimum corridor width of 80 cm, to allow installation and maintenance to be carried out safely and comfortably. page 4/6 Chapter 4 - Installation

47 4.4 Front End Installation The Front End assembly is bolted to two wooden supports (Kickbacks) that have been previously installed by the lane technicians to USBC/FIQ specifications (See Figure 4-). A special steel channel (Unistrut) is screwed to the wooden kickbacks. Special hardware is then attached to the unistrut to accommodate the Front End frame. Two studs ( and 2) are used to fix each side of the frame. A template supplied by Switch SA is used to ensure that the holes in the Front End frame are aligned with the studs on the unistrut and are in the correct position with regard to the marks (pinspots) on the lane. 2 Fig. 4- Front End Installation Chapter 4 - Installation page 5/6 SWITCH ENTERTAINMENT S.A.

48 User s manual! IMPORTANT! Front End assemblies have to be identified as Left Hand machines and Right hand machines. The easiest way to identify LH and RH machines is by checking the position of the front to-back wireways as shown in Figure 4-2. The left hand machine (Odd Lane) has the wireway on the right hand side 2. The right hand machine (Even Lane) 3 has the wireway on the left hand side 4. (Viewed from the lane side of the machines) Fig. 4-2 Left and Right hand The Front End assemblies should be transported to the supports (Kickbacks) on a manual pallet truck with the special fixture attached. The fixture ensures that the fixing points of the Front Ends will be at a suitable height such that the vertical range of travel of the pallet truck will allow the Front Ends to be lowered into position, and the pallet truck and fixture can be removed when in the lowest position (See Figure 4-3).! IMPORTANT! Before removal of the pallet truck and fixture, the four fixing points must be secured with washers and nuts to prevent the Pinspotter overbalancing towards the front, since the centre of gravity is in this area. Fig. 4-3 Front End Assembly page 6/6 Chapter 4 - Installation

49 The underside of the lower frame of the Front End should now be levelled at a height of 48 cm from the pindeck (See Figure 4-4). 48 cm 8 7/8 inches Fig. 4-4 Front End Position When all the Front End assemblies have been positioned and levelled, the Back End assemblies can be positioned. Chapter 4 - Installation page 7/6 SWITCH ENTERTAINMENT S.A.

50 User s manual 4.5 Back End Installation! IMPORTANT Back End assemblies must be identified as Left Hand and Right hand. This is done by checking the position of the Ball Exit. The two Ball Exits of an adjacent pair of machines must face each other as in Figure 4-5. Even Odd Fig. 4-5 Ball Exit The Back End assemblies should be positioned as close as possible to the Front Ends using a pallet truck. The final positioning should be done by hand. Back Ends can be positioned from left to right, or from right to left. The first Back End of a pair should be positioned behind the Front End (See Figure 4-6). The fixing holes of the Back End should be aligned with those of the Front End. The height and the level of the Back Ends are achieved by changing the length of the four jack screws (one on each corner). The ideal height is reached when the slotted holes on the Back (3) and Front Ends (2) form a +. The spacer (Fig. 4-6) (0 mm) provided with the hardware kit should be placed between the two frames to ensure correct spacing for Distributor operation. 3 2 Fig. 4-6 Back and Front Ends installation page 8/6 Chapter 4 - Installation

51 The next operation is to position the Horizontal Ball Exit (Fig. 4-7) next to the Back End. The height of the HBE should then be adjusted (see the screws 2 and 3) so that there is a slight drop-off from the ball exit on the Back End to the Ball door on the HBE. (See Figure 4-7). 2 3 Fig. 4-7 Horizontal Ball Exit Assembly Chapter 4 - Installation page 9/6 SWITCH ENTERTAINMENT S.A.

52 User s manual The second Back End of the pair of lanes can now be positioned and levelled in the same way as the first. It is good practice to ensure that the two adjacent Back Ends of a pair of lanes sharing the same HBE are at the same level. When the Back Ends have been bolted to the Front Ends, it is important to lock the jack screws with the hexagonal head screws provided, to ensure that they do not lose their adjustment due to vibration (See Figure 4-8). Fig. 4-8 Back End levelling 4.5. Back End motors and brackets The Back End motor brackets now have to be fitted to the frames. These assemblies are also Left Hand and Right Hand. Care should be taken to ensure that the correct assemblies are fitted (See Figure 4-9). Fig. 4-9 Back end motors The V-belts can be fitted when the motor brackets have been installed (See Figure 4-0). Fig. 4-0 V-belts page 0/6 Chapter 4 - Installation

53 4.5.2 Wireways and Covers, Control Box supports The Control Box support assemblies should be fitted first, as the wireways that hold the machine wiring are bolted to them (See Figure 4-). Install the front to back wireways with the hardware provided (Refer to Figure 4-). Chapter 4 - Installation Fig. 4- Control Box support page /6 SWITCH ENTERTAINMENT S.A.

54 User s manual Hand rails Install the Hand rails with the hardware provided (See Figure 4-2). Fig. 4-2 Hand rails Access steps A set of steps should be bolted to the machines as shown in Figure 4-3. Fig. 4-3 Access steps page 2/6 Chapter 4 - Installation

55 4.5.5 Pin Distributor The Pin Distributor pivots (Fig. 4-4) on a Support Tube that is fixed to the Back End frame. One Spacer washer provided in the hardware kit should be placed on the base of the tube. The tube should be coated with grease before the Distributor is installed. Slide the Pin Distributor onto the support tube until it is resting on the spacer washer previously installed. Fit the Drive Shaft from the Distributor to the Back End drive gearbox (Left hand and Right hand drive shafts are different lengths). Fig. 4-4 Pin distributor assembly Safety Guards! IMPORTANT!

Circuit Breaker incorporated overload rating: 6 Amperes Verification of electrical connections To check the connection of the phases, proceed as follows: Disconnect the Distributor drive shaft, if already installed.turn the pinspotters on using the Manual on/ off switch on the control box. Check the direction of rotation of all the motors on the pinspotters. If the rotation of ALL the motors is wrong, then two phases should be inverted inside the power supply cable socket. If individual motors need to have the sense of rotation changed, proceed as follows: Disconnect all motors on each of the two machines of the pair controlled by the Switch control box. Insert the power supply plug into the SWITCH control box. Re-connect one motor at a time and verify the sense of rotation as follows:. Table and Sweep motors Open the circuit breaker on the machine under test and plug in the Sweep or Table motor. Close the circuit breaker and turn the machine on using the Manual on Switch on the control box. Run the Sweep or Table manually from the Manual Sweep start or Manual Table start switch on the control box. Check that the direction of rotation is correct.if it is not, the power should be removed by opening the circuit breaker relative to the machine under test. The cover is then removed from the terminal strip on the motor, and any two of the three phases inverted. This will reverse the direction of rotation of the motor.the cover is then replaced on the terminal strip. The same procedure is followed for each motor in turn until the direction of rotation is correct. 2. Back End motors Ensure that the Distributor Drive Shaft is disengaged from the Back End drive gearbox, and that the circuit breaker is off. Re-connect the Back End motor plug to the socket on the rear of the Control box. Close the circuit breaker for the machine under test and turn the machine on using the Manual on switch.if the isolator switch on the control box is closed, the Back End motor should start to run.

General Guidelines - State of the machine: assembled and connected to the energy sources. - Main switch: Turned to Off (0) and isolated. - No. of operators: Not specified. - Personnel qualifications: operator; Mechanic; Electrician; Manufacturer s technician. 8.2 Technical Adjustments The adjustments should be carried out in the order they appear in the manual to ensure correct operation. Table and Sweep adjustments require that the drive motors have to be cranked by hand. BEFORE ANY MANUAL CRANKING HANDLE IS INSERTED IN A MOTOR,THE POWER SUPPLY PLUG TO THE MOTOR MUST BE DISCONNECTED.!! The motors used on the ST are equipped with an Electromagnetic Braking system, which should be disengaged before any motor is cranked manually. This is done simply by using the Brake Release Lever. If any adjustments to the table require the forward travel of the Table motor, the cranking handle must be inserted before the brake is released, otherwise the Table will run down under its own weight in the wrong direction. This is due to the fact that the Table home position is 355 and not 360. When the Table has been cranked sufficiently in the forward direction, the cranking handle may be removed and the Table will run down under its own weight. When it has stopped, the cranking handle is then inserted and the Table can be easily re-positioned as required for Fig. 8- Electromagnetic Braking system adjustment. Chapter 8 - Technical Adjustments page 3/30 SWITCH ENTERTAINMENT S.A.

99 User s manual 8.2. Sweep The height of the Sweep from the pindeck and the amount of travel towards the Back End are critical to the correct operation of the Sweep assembly. Height If the Sweep is too high with respect to the pindeck, the Sweep bar may override pins in the gutters and push them out of the machine and onto the lane, where they will have to be removed manually. Also, on first ball cycle, the Sweep bar may touch the # pin when it is suspended in the Respot Cell Fingers as it makes its run through to clear the fallen pins from the pindeck area. If the Sweep is too low with respect to the pindeck, and the Sweep bar touches any part of the pindeck or gutters, then premature wear will be caused to all parts affected. Drag on the Sweep will cause all the Rod Ends to wear, and the operation of the whole assembly will become erratic as a result. Length of travel The distance the Sweep bar travels towards the rear of the pindeck is also very important. If the Sweep does not travel far enough, pins standing near the rear edge of the pindeck may not be cleared away and will prevent the table from properly spotting the pins. Damage to the table and its component parts may result. If the Sweep travels too far back, a pin may become trapped between the flat gutter and the round part of the Sweep bar. This situation may cause breakages of the drive links on the Sweep assembly. Another consideration is the extra stress put on all the moving parts of the Sweep assembly due to the greater distance travelled in the same time period ( revolution of the Sweep motor). The increased speed of the Sweep makes the movement erratic, causing undue wear on the whole assembly Starting Point Adjustments Since there are several adjustments that are dependent upon each other, it is important to have a starting point before any other adjustments are carried out. The most important is the length of the connecting rod ( Fig. 8-2) which should be 0 3/8 (264mm) centre to centre. 2 Fig. 8-2 Connecting rod Fig. 8-3 Sweep rear position The next adjustment to be carried out is the length of travel towards the pindeck. The Sweep is brought to the extreme rear position, and has to be adjusted to knock over a pin at the furthest back position that the pin can remain standing. This can be easily determined by cranking the Sweep until the front of the Sweep bar is in line with the rear of the pinspots (see fig.8-3).this adjustment is carried out using the two adjusting rods 2 (see fig 8-2). To check this adjustment, two pins should be placed on the pindeck behind the 7 and 0 pins as far back as possible. The Sweep should then be run under power to ensure that the pins are knocked over. page 4/30 Chapter 8 - Technical Adjustments

100 5 mm Height Adjustment The first height adjustment of the Sweep bar should be done at the first guard position (66 ). The sweep should be stopped in this position and then the Sweep motor should be manually cranked one turn so that the sweep bar moves a little towards the rear of the pindeck. At this point, there should be 5mm clearance between the round part of the sweep bar, and the Adapter Block (Fig. 8-4) (part of the gutter.) Adjustment is achieved by lengthening or shortening the threaded part of the Threaded link 2 (Fig. 8-4). A level should be placed on top of the Sweep Bar (Ref. 4) and a mean distance of 5mm should be maintained between the Adapter Block and the rounded part of the Sweep Bar. Unscrewing the Threaded link will make it longer, and the Sweep Bar will be raised as a result. The lock nut must be made very tight after this adjustment is made. 4 When the Sweep Bar is correctly adjusted, and level, The Sweep should be moved forward to the line through the pin spots. The distance from the pindeck to the underside of the Sweep should be between 6-8mm. This is achieved by raising or lowering the Shock mount bracket.raising the bracket lowers the Sweep and viceversa (see 3 Fig. 8-4). When all adjustments have been carried out, the Sweep should be run under power to check for smooth operation. There should be no drag or contact with any other part of the lane or machine. The Sweep should also be level when it is travelling down from zero to 66 position, and from 270 to home (zero) position. Any out of level condition should be corrected by turning the adjusting rods (2 Fig. 8-2). When all Sweep adjustments have been done, and the operation of the Sweep is satisfactory, all locknuts should be checked for tightness, including any which have not been touched during the adjustment sequence. 3 Fig. 8-4 Height Adjustment Chapter 8 - Technical Adjustments 2 page 5/30 SWITCH ENTERTAINMENT S.A.

101 User s manual Table Adjustments ALL MOTOR PLUGS SHOULD BE DISCONNECTED BEFORE ENTERING ANY MACHINE FOR MAINTENANCE PURPOSES. The correct adjustment of the Table is paramount to the efficient operation of the ST. The Table should Spot and Respot the pins with little or no wobble. The adjustments should be carried out in sequence as they appear in this manual to ensure optimum performance. The table should be taken down manually to the lowest position in Spotting mode. Insert the manual cranking handle in the Table motor. Release the brake on the motor, engage the Spotting Latch manually (see Fig.8-5) and bring the Table to the lowest position (Bottom Dead Centre). The three points in Fig.8-6 are in line at this position (see, 2 and 3 ). Fig. 8-5 Spotting Latch 3 2 Fig. 8-6 Three points The Table should be parallel with the pindeck, and should be 8 mm ± mm above it. 8 mm ± Fig. 8-7-A Table position page 6/30 Chapter 8 - Technical Adjustments

102 2 If the Table is not parallel with the pindeck, the following corrective adjustments should be made: a) If the Table is out of parallel from front to back, i.e. it is low at the front and high in the rear (Fig.8-7-A), this is corrected by adjusting the two Stabiliser rods and 2 (Fig.8-7-B). Making the rods longer will lower the rear and raise the front and vice versa. b) If the Table is out of parallel from left to right, then shims 3 have to be used to correct this condition. Fig. 8-7-B 3 Fig. 8-8 Adjustment table c) If the Table is less than 6 mm or more than 0 mm from the pindeck, adjustment is carried out by changing the length of the Clevis (Fig. 8-9). (One turn of the Clevis will raise or lower the Table by approx. 3 mm). The correct positioning with respect to the pinspot pattern is fundamental to the smooth operation of the Table. The next adjustments to be carried out are to ensure that the positioning is correct with regard to the pinspot pattern on the Pindeck. Fig. 8-9 Clevis Chapter 8 - Technical Adjustments page 7/30 SWITCH ENTERTAINMENT S.A.

103 User s manual There are two simple adjustments to centralise the Table over the pinspot pattern: a) With respect to the 7-0 line. The back of the Table casting should be 8 (203 mm) from the rear of the pinspot line (see Fig.8-0). Adjustment is made using the slotted holes on the Table Support Legs (Front to rear) (see Fig.8-0) Fig. 8-0 Adj. respect to the 7-0 line b) With respect to the Kickbacks. The Table left and right sides should be equidistant with respect to the Kickbacks (see Fig.8-). Adjustment is made using the slotted holes on the Table Casting. (Side to Side) (see Fig.8-). Fig. 8- Adj. respect to the Kickbacks page 8/30 Chapter 8 - Technical Adjustments

104 Spotting Adjustments When the Table has been centralised as above, the next series of adjustments is carried out on the Table assembly to place the pins on spot. The first of this series of adjustments is carried out when the underside of the Table is 5 cm from the pindeck in Spotting mode (see Fig.8-2). Fig. 8-2 Toe-in adjustment 4 The grub screw on the locking collar 2 is loosened, and the collar is moved away from the Table leg to leave enough room to place a combination square between the bolt 3 and the shaft 4 as shown in Fig.8-3. The adjusting screw -2 Fig. 8-4 should be turned until the level shows a half bubble reading towards the rear of the pindeck. This is known as the Toe in adjustment. Make the lock nut tight on the adjusting screw before proceeding. 2 3 Fig. 8-3 Square position,6 mm Fig. 8-4 Chapter 8 - Technical Adjustments 2 page 9/30 SWITCH ENTERTAINMENT S.A.

105 User s manual Fig. 8-5 Measure the opening of the # pin using the Gauge #2 (see Fig.8-5). This is important, since any adjustment carried out on the # pin will apply to all the pins. There should be a little play on the gauge to assure that the cup opening is not too tight. Place the Gauge # 2 on top of the # pinspot, place a pin in the # spotting cup, and lower the Table slowly until the pin just touches the gauge. At this point the gap between the head of the adjusting screw and the back stop should be.6 mm (see Fig. 8-4). Adjustment is achieved by turning the Spotting Rod. At this point the only adjustment remaining to place the pins on spot is done using the 4 nuts on the Spotting Cup for side to side and back to front movement. Do not over tighten the nuts as the Cap on the rear of the cups may be broken.! NOTES. Please note that the following conditions have a direct bearing on the Spotting adjustments:. The length of the spring on the front of the Table Yoke. This spring should be under maximum tension before any adjustments are undertaken. 2. The tension of the 3 Torsion springs on the Table Yoke assembly. These springs may have to be adjusted to eliminate wobbling or falling pins after all the other adjustments have been carried out and the Table is checked under power. page 0/30 Chapter 8 - Technical Adjustments

106 Respotting Adjustments All motor plugs should be disconnected before entering any machine for maintenance purposes. These adjustments guarantee the efficient operation of the Respot Cells, with a view to achieving the following conditions: a) The Respot Cells should open and close uniformly and without any erratic movement. b) The Respot cells should be adjusted so that the pins are all held at the same height, and so that the Respot Fingers are all the same distance from the rubber bumpers when they are fully open. c) When the pins are being raised by the Respot cells, they should be held firmly and display very little, or no, movement during the travel of the Table. d) The pins should be respotted in the same position as they were picked up. e) On Strike and Off Spot cycles, the Respot cells must open in good time to allow the Spotting Cups to deliver the pins to the pindeck unhindered. Adjustments Remove Table and Sweep motor plugs. Before lowering the Table to do any adjustments it is worth loosening the locknuts on the connecting rod (Fig.8-6) as it awkward to reach when the Table is down. Fig. 8-6 Connecting rod Lower the Table manually as per the Spotting adjustments until it is all the way down. Remove all the linkages 2 (Fig. 8-7) on the Respot Cells including the main drive linkage attached to the Bell Crank. 2 Chapter 8 - Technical Adjustments Fig. 8-7 Linkages Fig. 8-7 Connecting rod page /30 SWITCH ENTERTAINMENT S.A.

107 User s manual Adjust the main drive linkage to have a dimension of 78mm-80mm between the centres of the holes. (See Fig. 8-8). Replace the linkage mm Fig. 8-8 Main drive linkage adj. Adjust the stop bolt (Fig.8-9) on the bell crank so that there is a gap of 0mm between the respot finger and the rubber bumper on the # 7 cell. Lock the nut on the stop bolt. Fig. 8-9 Stop Bolt 2 Adjust for minimum play between the Cam Link (Fig. 8-20) and the Cam Follower 2. This is done by changing the length of the connecting rod (Fig. 8-6). Re-attach all the remaining 9 respot cells and adjust the linkages to have the same 0mm gap as the number 7 cell. This will guarantee that the cell fingers open and close uniformly. Bring the Table to Zero (Home) position and lock the nuts on the connecting rod (Fig. 8-6). Fig Cam fallower page 2/30 Chapter 8 - Technical Adjustments

108 Adjust the stop bolt on the Shifter Link Cam.(See Fig 8-2) as follows: With the Table at zero, loosen the lock nut at the end of the Shifter Cam. Turn the screw clockwise sufficiently so that the head of the screw does not touch the back stop when the Shifter cam is brought down by hand (to close the respot cells). Turn the screw anticlockwise until the head just touches the back stop. From this point, the screw should be lengthened by 4 turns, and the lock nut tightened. This is to ensure that the respot fingers do not lock on to the necks of the pins. Fig. 8-2 Shifter Link Cam Check the distance between the fingers using Gauge # 2.(See Fig. 8-22). This measurement should be checked at the centre of the respot fingers, where the pins are usually held. The 5mm wide part should just pass with a little friction. The opening is adjusted by turning the small screw (Fig. 8-23) on the Yoke of the aluminium assembly at the centre of the respot cell. 2 Adjust all the remaining cells in the same way. This will ensure that the pins are all held at the same height during a first ball cycle, and that the respot cells will not lock onto the pins. Fig Gauge #2 Adjust the Finger Link (See Fig. 8-24). This adjustment determines how much movement is transmitted to all the assemblies that open and close the Respot Cells. A good starting point is a gap of 4 mm. This gap is achieved by altering the length of the Respot Rod. Fig Chapter 8 - Technical Adjustments Fig Finger link page 3/30 SWITCH ENTERTAINMENT S.A.

109 User s manual If the gap is too small, the action of the respot cells may be erratic, and cause the pins to wobble, and in extreme cases, there may not be enough room for the Finger Link to move to the other side of the Shifter Link, and the pins will not be released. This will result in the pins being suspended in the respot cells with the Table at zero. If the machine is then cycled, the Table will try to spot 0 pins on top of the ones already suspended in the respot cells, potentially causing damage to various assemblies on the Table. If the gap is too large, the cells may not close fully on the necks of the pins, and the pins may be dropped by the cells at any point during the first ball cycle. Even if the respot cells manage to hold on to the pins, it is still likely that they may not be released due to insufficient travel of the Finger Link. For correct operation of the respot cells, it is important that the 2 Back stop screws (Fig. 8-25) touch their respective stops when the cells are open and closed. Run the Table with a full set of pins and check for smooth operation. Fig Back stop page 4/30 Chapter 8 - Technical Adjustments

110 Spotting solenoid assembly There are two components in the Spotting Solenoid assembly that require correct adjustment: The Stop Lever, which holds the Shuttle in the closed position during a first ball cycle, The Connecting Link Assembly, which transmits the movement from the solenoid to the Spotting Latch. Fig Stop lever The Stop Lever is adjusted when the Table is at zero. The Back stop screw (Fig. 8-26) should be set so that there is just enough play to ensure the free movement of the Stop Lever so that it does not bind when the solenoid is energised. If the gap is too wide, there will be a noticeable noise when the play is taken up on a first ball cycle. If the gap is too small, the Stop Lever will lock against the stop bolt on a spotting cycle, and the movement will not be transmitted to the Spotting Latch. The Spotting cups will then not be turned to the vertical position, and the pins will not be spotted. 3-5 mm Fig Connecting Link Assembly The Connecting Link Assembly (see Fig. 8-27) is adjusted to determine the gap between the Spotting Latch and the Spotting Lever. The gap should be between 3mm-5mm. This is done by changing the length of the Connecting Link. The two nuts on the link should be tightly locked together when the adjustment is completed. If the connecting link is too long, the spotting latch will not engage the spotting lever, so the pins will not be turned to the vertical position and will not be spotted. If the connecting link is too short, the latch will engage the spotting lever on a first ball cycle, and the cups will try to turn when the Table is trying to pick the pins up. The movement to the Respot Cells will be blocked, the pins will not be picked up, and the first ball cycle will be lost. Chapter 8 - Technical Adjustments page 5/30 SWITCH ENTERTAINMENT S.A.

111 User s manual Adjustment of bin and shuttle The Bin and Shuttle should be correctly aligned above the Spotting Cups on the Table Assembly. When the Spotting Cups have been adjusted to place the pins on spot, the alignment can be checked Bin The Bin can be adjusted laterally using the slotted holes on the End Caps (see Fig.8-28). It should be moved until the feeding pockets in the Bin are correctly aligned with the Spotting Cups on the Table. Fig Bin Adjustment Shuttle 2 The Shuttle can be adjusted for height with respect to the Bin, (see Fig.8-29) by changing the length of the left and right hand Connecting Rods. The correct distance is 22 mm, and this is checked using the gauge provided 2. The Shuttle can also be adjusted to alter the point at which the pins will be released into the Spotting Cups. 22 mm Fig Shuttle Adjustment This is done by changing the length of the Shuttle Drive Link (see Fig.8-30). The optimum distance between the Shuttle and the rear of the Bin is 44 mm, and is checked using the gauge provided 2 (Fig. 8-30). 2 Fig Shuttle drive link The alignment with the Bin can also be adjusted by repositioning the Shuttle return spring (Fig. 8-3) on the strap.

112 8.2.3 Distributor adjustments In order for the ST to perform at its best, it is essential that the Distributor unit is correctly adjusted and maintained. Many problems can be created by a malfunctioning Distributor. It is very important that any defects are identified and corrected as soon as possible. Many problems which are attributed to the Distributor are in fact due to other causes, so it is important that any malfunctioning unit is observed carefully to determine the origin of any defects. Some other potential sources of pin feeding problems are:. The Pin Guide Rail 2. The Bin and Shuttle assembly 3. A dirty Pin Wheel Distributor Adjustments Before any other work can be carried out on the Distributor, it is essential that the Orientation Pan, which turns the pins as they exit the Pin Wheel, is made level. This will also ensure that the Distributor Post is plumb. This simple adjustment will ensure that the height of the distributor is equal at the 7 and 0 pin positions, and to ensure maximum lateral travel to each side. The adjustment is made by placing a spirit level across the pan as shown in Fig Fig Distributor Adjustment Fig Distributor Adjustment Loosen the two bolts ( Fig. 8-33) at the lower rear of the Distributor Support Bracket and move the assembly laterally until the Orientation Pan is level. When the adjustment has been made, tighten the locknuts. The next step is to check the height of the Distributor above the Bin Assembly. A good starting point is to place 2 pins in the # 5 pin position in the bin, then drive the distributor to the zero, or # pin position. The Belt Guard should be close to the top pin in the # 5 position, but not touch it. As well as giving a good starting point for height adjustment, this will also lessen damage to pins by the Belt Guard when the Bin is full of pins and the distributor moves forward from the # 9 position to the # position. The height of the Distributor can be adjusted in two places: a) at the front of the distributor support bracket shims or washers can be placed between the bracket and the cross member as shown in Fig Fig Height Distributor Adjustment Chapter 8 - Technical Adjustments page 7/30 SWITCH ENTERTAINMENT S.A.

113 User s manual b) The distributor can be removed and shimming washers installed on the support tube as shown in Fig Whatever method is used, it is important that the distributor is not too high at either the Pin Wheel or the Bin. Fig Height Distributor Adjustment 2 The next adjustment is to centre the distributor at the # position. Before any adjustment is carried out, it is important to verify that the distributor drive Pinion (Fig. 8-36) and the Index cam 2 are correctly aligned. There is a timing mark on each of these gears and these must be aligned for correct operation. Fig Index cam position Centralise Distributor at # Position The Back End motor should be running to ensure correct adjustment. If adjustment is required, loosen the lock nut on the Safety Link (Fig. 8-37) and turn the Tube Link clockwise or anticlockwise until the distributor is correctly aligned with the centre of the # position on the Bin. Tighten the locknut on the Safety Link. Fig Safety link! Notes. See Adjustment of Bin and Shuttle for further alignment procedures. page 8/30 Chapter 8 - Technical Adjustments

114 Distributor assembly It is recommended that adjustments to the Distributor assembly be carried out on the Distributor Support Fixture. This fixture gives easy access to all moving parts on the Distributor. A suitable location for the fixture should be found in the Centre workshop, giving both adequate light and room to manoeuvre. Before any adjustments are made, it is important to visually inspect the Distributor for any obvious signs of wear and tear. The length of the belt should be checked, by making sure that the belt is not too long, or has excessive wear to either side. If the belt is too long, but otherwise in good condition, it may be shortened. Any of the 3 rubber bumpers that are worn should be replaced. Remove the Belt Tensioner Spring and then the belt by opening the Belt Lacing. Visually inspect the parts which are now more easily accessible. The sequence of adjustments should be followed as described below. 2 Fig Clutch plate & stop blade 3 The first adjustment to be made is to ensure correct alignment between the Clutch Plate stop 2 and the Stop Blade (see Fig.8-38). The lower blade of the Stop Blade should align with the stop on the clutch 2 plate when the following conditions are met:. The Trip Support Casting 3 must be resting on the rubber bumper (Fig. 8-39) on the Trip Stop Bracket when the Stop blade and clutch stop are aligned. 2. The Trip Rod (Fig. 8-40) must be able to move up and down freely. 3. Neither of the two nylon rollers (Fig. 8-4) on the Trip Rocker 2 should be touching the Trip Rod. In order to align the Stop Blade and the Stop on the clutch, it will be necessary to bend the Trip Stop Bracket. This can be done easily using a large adjustable wrench or a pair of Gas Pliers. Fig Rubber bumper 2 3 Fig Trip rod; 2-Trip stop rod; 3-Carriage tube Chapter 8 - Technical Adjustments 2 Fig. 8-4 Trip Rocker page 9/30 SWITCH ENTERTAINMENT S.A.

115 User s manual Fig Eccentric bearings The next adjustment is to make the Carriage Tube 3 parallel with the Trip Stop Rod 2 (Fig. 8-40). This is done by altering the position of the two front Eccentric Bearings (example Fig. 8-42). When loosened and rotated, they will rise and fall, changing the position of the Carriage Tubes 3 (Fig. 8-40). When the Carriage Tube is parallel with the Trip Stop Rod 2 (Fig. 8-40), and the Carriage Assembly is moved in and out, the two nylon rollers (see Fig.8-43)on the Trip Rocker should not touch the Trip Stop Rod at any point during the travel. The Eccentric rollers should be tightened after adjustment, but must allow the Carriage to travel in and out freely. The length of the Trip Rod should now be adjusted so that there is 3 mm - 4 mm gap between the rod and the lower roller (see Fig.8-43). This adjustment ensures that the heaviest part of the pin will be past the end of the belt and on top of the Trip Arms without any resistance. The weight of the pin can then exert maximum leverage on the Trip Rocker to release the clutch via the Stop Blade Clutch The Clutch assembly consists of the following component parts (Fig. 8-44): Fig Trip rod length adjustment Fig Clutch assembly page 20/30 4. Pinion The Pinion gear meshes with the Index Cam gear to transmit the motion required to move the Distributor Assembly from one pin feeding position to another. The Pinion completes one revolution to move the distributor from one feeding position to another. The Pinion and the Index Cam have Timing Marks which must be aligned at the # pin feeding position. 2. Friction disc The Friction Disc is sandwiched between the two clutch plates. It is made of plastic. 3. Drive plate. The Clutch drive plate is driven continuously. The centre of the plate has a helical shape and meshes with a plastic Worm Wheel. The worm wheel maintains the drive plate in a vertical position parallel to the driven plate, with the friction disc between them. The drive plate is connected to the drive shaft via a torsion spring, and the amount of pressure exerted on the driven plate is dependent upon the tension of the spring. 4. Clutch driven plate The other side of the Pinion is connected to the Clutch driven plate. The plate has a lug, or Stop, which is held by the Stop Blade, and can only revolve when a pin has pushed down the Trip Arms, and the Stop Blade has been driven downwards via the trip mechanisms. The driven plate receives its motion from the Drive Plate via a Friction Disc. The Drive plate is driven continuously by the Back End motor. The pressure between the clutch plates is regulated by a Torsion Spring, which is adjustable. 5. The Torsion spring is fixed to the Drive shaft by a 2-sided plate which slips over a nut on the shaft. The adjustment of the spring is carried out by moving the plate on the nut. Chapter 8 - Technical Adjustments

116 Clutch Adjustment! It is important that the interior of the clutch plates is free of oil and grease. Check the alignment of the timing marks on the Pinion and the Index Cam. The adjustment of the clutch spring is important for the reliable operation of the Distributor. A good starting point for this adjustment is ¾ of a turn from zero. Remove the spring plate from the nut and release the tension on the nut on the shaft. Hand tighten the nut onto the Plastic Worm. Wind the spring for ¾ of a turn anticlockwise and replace the plate on the nut. Put some grease on the contact faces between the Stop Blade and the Stop on the clutch plate. Run the distributor and check the operation. If the Distributor stalls between any feeding positions, particularly and 6-0-9, the tension of the spring should be increased by one position on the spring plate at a time, until smooth operation is achieved. If too much tension is put on the spring, the Stop Blade may not be able to release the Clutch drive plate and irregular pin feeding will result Pin Guide Rail Fig Pin guide rail Chapter 8 - Technical Adjustments The Pin Guide Rail supports the pins when they pass the point at which they would fall out of the Pin Wheel by the effects of gravity. The Pin Guide Rail can be adjusted both for height and to determine the drop off point of the pins at the Orientation Pan. The height adjustment to the Pin Guide Bracket is done by loosening the nuts on the Shock Mount and moving the Guide rail up or down. The Drop off Point is adjusted by loosening the nuts on the Guide rail and sliding the rail closer to or further from the Orientation Pan. The starting point for the height adjustment is determined by placing a pin in a Pin Wheel pocket and stopping the Wheel when the pin is close to the centre of the Pin Guide Rail. Move the Rail up or down until the pin is held in place but not under too much pressure from the Guide Rail shock mounts. If the Guide rail is too high, the pin will be pushed out of the PinWheel like a slingshot, travel too quickly, and may either fall off or remain stranded across the Orientation Pan. If it is too low, the pins will exhibit too much movement in the pin pockets on the Pinwheel, and the transfer of the pins to the Orientation Pan will not be consistent, causing pin feeding problems. The starting point for the Drop off point adjustment is the furthest away from the Orientation Pan. Run the distributor and check for smooth transition from the pin wheel to the Orientation Pan. Move the Guide rail until the transition is smooth and consistent, especially when the pins arrive head first, as this is the most challenging condition. Try to turn the pins to the head first position on the carpet belt before they enter the Pinwheel, and check for smooth transition at the Orientation Pan in every pin feeding position on the Bin. Many problems are created by a wrongly adjusted Pin Guide Rail, which can be mistakenly interpreted as a malfunctioning Distributor. It is important, therefore, that pin feeding problems be correctly identified by observing the operation of all the parts involved until the cause is determined. page 2/30 SWITCH ENTERTAINMENT S.A.

117 User s manual Pin Ejector The Pin Ejector (see Fig.8-46) is designed and positioned to eject any pins that are not correctly seated in the Pinwheel pockets, so that they cannot continue the upward journey only to fall out from a greater height, or even enter the Distributor the wrong way round (head first). The mechanism should be adjusted so that the roller is 6-8 mm from the pins as they pass in the Pinwheel pockets. The adjustment is carried out by loosening the two through bolts on the metal kickbacks and sliding the mechanism in or out. Fig Pin Ejector Orientation Pan The Orientation Pan has only limited adjustment, with regard to the distance from the Pinwheel. The starting point for adjustment of the Orientation pan is to place it as close to the Pinwheel as possible, but not to touch it throughout the range of action of the distributor. A good test is to bring the distributor to the # 7 pin feeding position and check for contact with the Pinwheel Pin seating rod Fig Pin seating rod The Pin Seating Rod is situated above the Pin Ejector and is designed to push the pins into the pin pockets in the pinwheel. The rod is mounted on a rubber bumper which is fixed to the machine frame. If the rod is too far away from the Pinwheel, the pins may not be correctly seated in the Pinwheel and may enter the distributor head first, causing a pin feed problem on the Bin. If the Rod is too close to the Pinwheel, it will touch the triangular pin holders and damage will occur to both parts. Adjustment is made by loosening the nut on the top of the rod, and re-positioning it as required. The rod should be positioned so that it is 2-5 mm from the tip of the pin holder triangles on the Pinwheel (see Fig.8-47). page 22/30 Chapter 8 - Technical Adjustments

118 8.2.5 Cams and microswitches The Cams and Microswitches sychronise the movements of the Table and Sweep. The correct adjustment of the microswitch levers and switches is important for the smooth operation of the ST pinspotter.. Actuating screws. The microswitch actuating screws must be correctly adjusted to ensure that the timing of all microswitches is uniform. All microswitches should be adjusted in the same way and to the same tolerances. 2. Cams. The Table and Sweep Cams are adjusted to regulate the stopping and starting positions of the Table and Sweep motors. Stopping and starting positions should only be adjusted using the relative Cams Adjustment of Cams and microswitches. Actuating Screws The adjustment of the Actuating Screws can only be done on the high part of the Table and Sweep Cams. Position the cams so that the microswitch lever is riding on the high part of the cam. This can be done electrically by using the manual run Sweep and Table switches on the front end Box, or by hand with the motor cranking handle (REMOVE MOTOR POWER PLUGS WHEN MANUAL ADJUSTMENT IS REQUIRED.) Loosen the locking nuts on the Actuator Screws. Using a 3 mm Allen key, turn the Actuating Screws clockwise until the click is heard from the microswitch. This is the point at which the head of the screw causes the microswitch to open or close. From this point, the screw should be turned anti-clockwise for /2 turn (80 ). All the Actuating screws should be adjusted in this way. 2. Cams The Cams should now be adjusted to determine the stopping positions of the Table and Sweep. Name of Function of Cam Cam SA Stops the Sweep at 270 Second guard position. Drives the Sweep from 270 to Zero. SB Stops the Sweep at 66 First guard position SC Provides Interlock protection with TC * TA Drives the Table to Zero TB Starts Sweep run-through to clear pindeck. TC Provides Interlock protection with SC * SC and TC monitor the Table and Sweep to prevent a collision and * damage. Either switch can be closed without consequence, but when both are closed, the power is excluded from Table and Sweep motors. Following the adjustment of the Actuating Screws, the Pinspotter should be cycled to verify the stopping positions of the Table and Sweep. If the stopping positions are incorrect, the Cams will have to be adjusted. Chapter 8 - Technical Adjustments page 23/30 SWITCH ENTERTAINMENT S.A.

119 User s manual Sweep Cams The Sweep has two stopping positions that can be adjusted by moving the Cams. These are at 66 and 270 (see table above). The SB cam should be adjusted to correct the stopping position at 66 (First Guard position). If the Sweep bar stops too soon (does not reach 66 ), the cam will have to be retarded. This is done by loosening the clamp stud on the SB/SC cam, and rotating the cam in the opposite direction of the movement of the drive shaft. If the Sweep bar passes 66, the cam will have to be advanced. This is done by loosening the clamp stud on the cam and rotating the cam in the same direction as the movement of the drive shaft. The SA cam should be adjusted to correct the Sweep stopping position at 270 (Second Guard position). This adjustment automatically corrects the Sweep stopping position at Zero. The adjustments to advance or retard the SA cam are identical to those of the SB cam above. Table cams The Table cams are all connected together, so only one position requires adjustment, and that is the Table Zero, or Home position. This is done by ensuring that the Latch Actuator roller stops in the correct position as shown in Fig This ensures that the Solenoid is fully energised before the Latch Actuator roller makes contact with the Cam Lever on the Solenoid assembly. Since TB gives the signal for the run through of the Sweep on st. ball, it is important that this adjustment is correct. If the Cam is too far advanced, the Sweep motor will start too soon and the Sweep bar may touch the # pin suspended in the respot cell. Fig Table cams The Cam adjustments are trial and error, so several attempts may have to be made to find the correct position of the cam on the drive shaft. Always remember to tighten the clamp stud after each adjustment. page 24/30 Chapter 8 - Technical Adjustments

120 8.2.6 Horizontal Ball Return System The Switch ST uses a Horizontal Ball Return system, whereby the ball is returned to the player under the kickbacks. The system consists of two separate mechanisms:. The Ball Sensor Unit This part is driven continuously by a motor via a reduction gearbox. The system is designed to keep pins out of the Return Track, and if necessary, expel them. The Pin sensor gives way to a ball entering the Ball door, but if the ball exit remains blocked (e.g. by a pin in front of a ball), the sensor will lock by means of a cam and cam follower, and any obstruction will be removed by force. When the drive pulley completes one more revolution, the cam system is reset to zero and the sensor will once again give way to a ball entering from either lane. 2. The Ball Accelerator As its name suggests, the Ball Accelerator increases the speed of the ball so that it can travel back under the lane to the player. The unit is motor driven via a pulley and belt. The Ball Exit is equipped with a system of two latches, which differentiate between a ball and a pin due to the distance between them. When the latches are both depressed, the Ball Gate will open, and the ball will travel downwards towards the Ball Accelerator. The contact between the ball and the Accelerator will impart the speed required to send the ball back to the player Adjustment of Ball sensor Unit Before any adjustment can be made, the drive belt (Fig.8-49) should be removed so that the unit may be operated by hand. Fig.8-49 Adjustment of ball sensor unit Fig.8-50 Adjustment of ball sensor unit The Paddle must be free to move laterally from one ball door to the other without touching the Ball door weldments. If required, shimming can be done at the rear of the Ball sensor unit where the unit is fixed by 4 bolts to the frame of the horizontal return. The Paddle can also be moved forwards and backwards by loosening the clamp stud (Fig. 8-50) on the bottom of the Support casting Chapter 8 - Technical Adjustments page 25/30 SWITCH ENTERTAINMENTS S.A.

121 User s manual Check that the sensor unit is centralised between the side frames of the Horizontal Return Unit. Reposition the Ball Sensor as required ensuring that it is in the centre of the two side frames. When the paddle is in the centre of the unit, check the position of the Cam Weldment (Fig. 8-5). Push the left and right side rollers forward to ensure that they are in the zero position. At this point the distance between the Cam and the rollers 2 and 3 should be equal on each side, around 3-4 mm. If the distance is too great, the trip cams will not travel downwards sufficiently to lock onto the Cam Follower, and pins will not be pushed out of the ball exit. If the distance is too small, light bowling balls will be continually pushed out of the ball exit, as the Cam Weldment will meet too much resistance from the rollers. The ideal distance will be achieved when the gap between the Cam weldment and the rollers is as large as possible, and the trip cams engage the Cam follower sufficiently to push pins blocked by balls out of the ball exit. Any re-positioning is carried out on the two bolts on top of the Cam Weldment 4 (Fig. 8-5). 4 Fig.8-5 Adjustment of ball sensor unit The position of the Cam Follower (Fig. 8-52) should be checked. The Cam Follower should be high enough to engage with the Trip cams on each side when they are in the down position, but not be too high as to make contact with the Trip cams when they are in the up position, and will not allow balls to enter the ball exit. The height of the Cam Follower is determined by shimming washers 2. 2 Fig.8-52 Adjustment of ball sensor unit page 26/30 Chapter 8 - Technical Adjustments

122 Fig.8-53 Drive pulley The first adjustment concerns the lateral movement of the sensor unit. It is important that the travel should be equal from side to side. This is done by setting the position of the drive pulley (Fig. 8-53) to zero (bring the shaft on the eccentric drive plate as close as possible to the centre of the pulley). Alter the length of the connecting rod 2 so that the travel is equal from side to side, and then adjust the overall travel by moving the Eccentric Plate on the drive pulley away from the centre. The side to side adjustment is correct when the Paddle tube (Fig. 8-54) touches the Rubber Stops on each side of the unit, and the Cam Weldment (Fig. 8-52) over travels by at least 2 millimeters, but does not touch the rollers. This adjustment ensures that the paddle has sufficient travel and strength to remove any pins from the ball exit. It should be noted that no lubrication should be used on the Ball Sensor Unit. The correct operation of the Trip Arms depends on friction, and any contact with oil or grease will compromise the efficiency of the mechanism. Fig.8-54 Paddle Chapter 8 - Technical Adjustments page 27/30 SWITCH ENTERTAINMENTS S.A.

123 User s manual Adjustment of horizontal ball shooter This part of the Horizontal Ball Return unit gives the ball the speed required to return under the lanes to the players. It consists of two main components: the Ball Gate, and the Accelerator unit. Ball gate The Ball Gate is a system of latches and levers which can differentiate between a ball and a pin by recognising the shape of the ball. Two sensors are placed in such a way that only the shape and weight of a bowling ball can trigger both of them at the same time. This condition will cause the Ball Gate to open and allow the ball to roll forward and downwards and under the Accelerator unit s belt. The speed of the ball is accelerated to give it the impetus required to reach the Ball Return unit in the players area. Adjustment of Ball Gate The Ball Gate Assembly should be removed from the Accelerator to facilitate the adjustment. This is easily done by removing the 4 bolts that fix it to the Accelerator frame. All adjustments can now be carried out on the workbench. Before any adjustments are carried out, check for broken or damaged parts and loose hardware as the Ball Gate assembly is subjected to a lot of vibration Adjustment of the Ball Gate Remove the Ball Gate Assembly from the Ball Exit frame. Push the Lower, (rear) ball sensor down as far as it will go. Adjust the Trigger Plate Back Stop (Fig. 8-55) until mm of the Trigger is showing on the inside of the plate (Fig. 8-55). Tighten Back Stop lock nut. Adjust the Upper, (forward) ball sensor starting from a low position, raising the level of the sensor until a ball can open the Ball Gate. Check adjustment of Ball Gate with a selection of both light and heavy balls. All weights of balls should trigger the Ball Gate without hesitation.
