14 OPERATION SAFETY PRECAUTIONS Warning Label - READ and UNDERSTAND. USING THE JOB SELECTOR 1. Refer to the Job Selector chart on the top panel of the control console for information about the recommended blade pitch, band speed, and cutting rate. This information is listed according to type of material to be cut and its thickness. The Job Selector also has a checklist for proper machine operation and reference notes about band speed, feed force, etc. Job Selector recommendations can be adjusted to meet special sawing requirements and are a general guide for correct cut-off sawing on a properly maintained DoALL saw. They are based on cutting annealed, scale-free, solid material using a Imperial Bi-Metal saw blade. Typical Job Selector. 10

15 CUTTING CAPACITY 1. The standard machine's cutting capacity is: At 0 tilt: 25 inches (635.0 mm) wide by 25 inches (635.0 mm) high for rectangular/square stock; 25 inches (635.0 mm) diameter for round stock. At 45 left tilt: 25 inches (635.0 mm) wide by 17 inches (431.8 mm) high for rectangular stock; inches (444.5 mm) diameter for round stock. At 45 right tilt: 25 inches (635.0 mm) wide by 17 inches (431.8 mm) high for rectangular stock; 17 inches (431.8 mm) diameter for round stock. 2. Cutting capacity may vary with addition of accessories and will be noted when applicable. Vise Capacity 1. The vise(s) maximum opening is inches (647.7 mm). CONTROL CONSOLE Electrical Control Panel 1. Hydraulic Start. Push this black button to start the hydraulic pump motor. The hydraulic pump motor must be on to operate the machine. 2. Cycle Start. Push this black button to start the automatic sawing cycle when the Operation selector is in the "auto" setting. 3. Operation. This selector switch allows the operator to choose "set-up", "manual" or "auto" mode. In the "set-up" setting, the saw band does not run while the saw head travels forward or in reverse through its stroke. The saw head must be in the fully retracted position for such pre-sawing operations as tilting the head or post movement is allowed. In the "manual" mode, the saw head travels forward to complete the cut, then the sawing head and saw band movement will stop. During "auto" mode, all appropriate selector switches must be set at the "automatic" setting. Coolant, band speed and feed rate must be set and the workpiece must be correctly positioned for the cut. When the Cycle Start button is pushed, the saw head travels forward to complete the cut, the saw band stops and the saw head retacts to the rear limit switch. To start the next cut, reposition the workpiece, start the saw band and push the Cycle Start button. 4. Stop (Emergency Stop). Pushing this red mushroom head pushbutton stops all machine motors (band drive, hydraulic pump, coolant pump and chip conveyor) simultaneously. Before the machine can resume operation, the Emergency Stop pushbutton must be reset (turn the button head clockwise until it pops up). 5. Post. This selector switch with "down", "hold", and "up" settings regulate post movement. The "hold" position stops post movement. When the saw head is tilted, make sure the post is positioned to clear the material. Failure to do so will result in damage to the post. Control Console. 11

16 CONTROL CONSOLE (Continued...) Typical Pushbutton Panel. 6. Approach Rate. This selector switch with "normal" and "heavy duty" settings allows a choice of head approach rate toward the material to be cut. The "heavy duty" setting is a slower than "normal" travel rate and used when cutting large, tough material. 7. Coolant. Four position selector switch with "aux", "off", "band on", and "on" settings. (a) "Band on" allows the flood coolant system to operate when the band drive motor is running; (b) "on" allows the flood coolant system to operate without the band drive motor running; (c) "aux" is used for the optional cutting lubrication system; (d) "Off" turns off either system. Older machines had the Coolant selector switch with "off" and "normal" settings located on the side of the rear electrical enclosure. Turning the selector to "normal" activates the coolant pump and allows the operator to control volume with the valve on the left front of the machine. 8. Vise. This selector switch with "open" and "close" settings controls the clamping and unclamping of the left hand vise. It also simultaneously controls the right hand vise with the left vise when suplied. Make sure the vise jaw is opened wide enough when moving material through the vise jaws. 9. Feed. Use this selector switch with "rev" (reverse), "fwd" (forward) and "auto-off" settings to regulate the direction of saw head movement. The "reverse" or "forward settings are used during manual operation. Turn the selector to "auto-off" before putting the machine into automatic cycle operation. 10. Tilt. This selector switch with "left", "hold", and "right" settings regulate the direction of head tilt and operates ONLY when the Operation selector switch is in the "set-up" position and the sawing head retracted fully. Turn the selector to "left" or "right" causes the head to pivot in that direction. Turn the selector to "hold" will stop head movement when the desired angle is reached. 11. Band. This selector switch with "stop" and "run" settings regulates the starting and stopping of the band drive motor. Hydraulics must be running before the band drive motor can be started. Other Controls 1. Chip Conveyor. This selector switch with "off" and "on" settings operate the optional motorized chip conveyor. 2. Laser. This selector switch turns the line-up laser "on" and "off". To avoid eye damage, DO NOT stare into the laser beam. 12

17 CONTROL CONSOLE (Continued...) 3. Band Tension. This selector valve with "tension", "release" settings and a center position for "hold" is used when changing saw bands. The control is located on the rear side of the column and accessed from the left side. Turning the selector to release lowers the upper bandwheel and enables saw band removal or installation. The center position or hold setting stops bandwheel movement and allows the operator to position the saw band over the bandwheels. The tension setting raises the upper bandwheel and automatically provides correct band tension. DO NOT operate the band drive motor unless band tension is on. 8. See the "Accessories" section of this manual on controls for the Variable Vise Pressure and Nesting Fixture options. Hydraulic Control Panel 1. Band Speed. This keylock adjustment valve allows the operator to set and maintain infinitly variable band speed between 60 and 300 fpm (18 and 90 m/min.). Refer to the data plate to the left of the valve for equivalent band speeds which can be reached with different valve settings. Turn the knob clockwise to increase the band speed, counterclockwise to decrease it. When setting band speed, the operator should try to obtain a vibration free speed level. Vibration while cutting generally indicates a need for a lower speed. If the vibration is severe, retract the saw head slightly from the stock, then adjust the band speed and resume cutting. The Band Tension selector must be at the "tension" position before the saw head will traverse. 4. Coolant. There is two (2) valves that regulate coolant flow to various areas of the machine. One valve is located to the left and below the control console and regulates coolant flow to the upper saw guide. The other valve is located under the step on the left side of the machine base near the coolant pump and regulated the coolant flow to the band drive motor and chip pan area. Turn either valve counterclockwise to increase coolant flow; clockwise to decrease the flow. 5. Feed Rate. This valve is used to regulate the linear travel of the sawing head towards the workpiece and is located on a bracket attached to the left side of the control console. Turn the knob counterclockwise to increase feed rate; clockwise to decrease the rate. The valve s lower locking knob or set screw helps maintain the setting. 6. Head Reverse Rate. Also located on the left side of the control console, this valve is used to regulate the reversing speed of the saw head. Turn the knob counterclockwise to increase the reversing velocity; clockwise to decrease it. The valve s lower locking knob or set screw helps maintain the setting. 7. Miter Meter. The unit, mounted below the Feed Rate and Head Reversing Rate controls, has a LCD window displaying the direction and degree of head tilt. Push the button or rotate the thumbscrew to turn the "power" to the unit on. 13 Typical Hydraulic Panel. 2. Band Feed. This control valve is used to adjust the saw band's feed force against the workpiece. Feed force is servo-maintained and infinitly adjustable between 0 and 22 ipm (0 and mm/min.). Turn the knob clockwise to increase the band feed, counterclockwise to decrease it. The valve s lower locking knob or set screw helps maintain the setting. 3. Band Feed Gauge. This indicator gauge located directly above the Band Feed valve registers the amount of pressure being directed against the workpiece. Material Handling Controls 1. Conveyor Speed. This selector switch with "low" or "1" and "high" or "2" settings regulate the speed of the conveyor(s). When the selector is in the "low" or "1" position, the conveyor maximum speed is reduced to about 30%.

18 CONTROL CONSOLE (Continued...) 2. Infeed Conveyor Enable. This selector switch with "on" and "off" settings allows the operator to turn the power off or on to the conveyor. This is used in conjunction with the Conveyor Speed/Direction control. 3. Outfeed Conveyor Enable. This selector switch with "on" and "off" settings allows the operator to turn the power off or on to the conveyor. This is used in conjunction with the Conveyor Speed/Direction control. 4. Conveyor Speed/Direction. This two position joystick allows the operator to adjust the conveyor speed and direction of material flowing through the machine. The Infeed and/or Outfeed Conveyor Enable selectors must be "on" for this control to operate. Moving the joystick to the right will convey the material to the rear of the machine; moving the joystick to the left will convey the material forward on the system. Blade Guards Contact your DoALL sales representative for complete information about saw bands and their applications. 1. The machine has several guards for operator safety and protection. All guards must be in place before any sawing procedure is started. Post Guard. This guard is attached to the bandwheel door and extends up towards the bandwheel. Column Guard. This guard is mounted on the head column and located between the bandwheels. Saw Guides 1. The upper and lower saw guides both have zeroclearance, carbide-faced, spring-loaded inserts. The inserts provide support necessary to help maintain sawing accuracy. Back support is provided by the pivoting carbide back-up inserts. The rate of travel in either direction is controlled by how far the joystick is moved from center. 5. Workstop. This selector switch with "up", "down' and "adjust" settings control the position of the optional workstop. SAW BAND PREPARATION Saw Band Recommendations 1. A high-speed DoALL Imperial Bi-Metal Super Silencer saw band with protective Saw Cap is supplied with the machine. Band length is inches ( mm); width is 1-1/2 inches (38.1 mm); recommended gage is inch (1.3 mm). Older machines had a band width of 1-1/4 inches (31.7 mm) with a gage of inch (1.1 mm). 2. A machine in correct adjustment, good operating condition and using proper cutting fluid is essential to efficient sawing. 3. Proper blade care should include: (a) Pushing uncut stock away from the saw band; (b) Using correct band speed, feed force and cutting fluids during operation; (c) Removing scale from stock before sawing; (d) Keeping the protective Saw Cap over blade teeth until installation time. Typical Saw Guide. Saw Guide Insert Adjustment 1. Loosen the adjustment screw at least two (2) turns counterclockwise on each saw guide. Then: (a) Remove the saw band (see below); (b) Turn the insert adjustment screw clockwise until it touches the fixed insert and then back two (2) full turns; (c) Replace the saw band (see below); (d) Turn the adjustment screw two (2) full turns clockwise to provide correct pressure against the saw band. 14

19 SAW BAND PREPARATION (Continued...) Saw Guide Insert Components. 2. This applies to both upper and lower saw guides. Saw Band Removal Always use extreme care when handling saw bands. Wear gloves. 1. Before removing the saw band, set the machine to the following conditions: (a) Hydraulics are on; (b) Band drive motor is off; (c) Coolant is completely shut off; (d) Saw head is vertical and completely retracted; (e) Position the post at the midrange height. 2. Move the Band Tension selector switch to "release". Then: (a) Open the upper bandwheel door; (b) Loosen the band brush bracket screw and move the brush aside; (c) Loosen the saw guide insert adjustment screws two (2) full turns counterclockwise; (d) Carefully remove the old, worn or broken saw band from between the saw guide inserts and both bandwheels; (e) Carefully work the saw band out from the column guard and dispose the saw band immediately. Saw Band Installation Always use extreme care when handling saw bands. DO NOT attempt to change saw bands while the band drive motor is running. 1. Carefully follow all "Saw Band Removal" procedures. Then: (a) Use the Flushing Hose to clean areas around the saw guides and inserts, plus the drive and idler bandwheels; (b) Wiper with clean rag. 2. Maneuver the saw band into the column guard. Then: (a) Carefully position the saw band around the drive and idler bandwheels with the saw band's back edge resting against each bandwheel's rear flange; (b) Move the Band Tension selector switch to "tension" to apply just enough tension to hold the saw band in position, then move the selector to the center position to "hold". 3. Slip the saw band between the saw guide inserts by twisting it 90 using the supplied saw band twist tool so the blade teeth are facing the front of the machine and pointing downward. Then: (a) Turn the adjustment screw two (2) full turns clockwise to provide correct pressure against the saw band; (b) Remove the protective Saw Cap from the saw band; (c) Close the the upper bandwheel door; (d) Move the Band Tension selector switch to "tension" to apply full tension to the saw band. 4. Turn the Band selector switch to "run" and operate at a very low speed to check for proper band tracking against the each bandwheel rear flange. Band Tension Adjustment 1. Located on the rear side of the column and accessed from the left side, band tension is hydraulically applied and maintained. DO NOT operate the band drive motor unless band tension selector is in the "tension" position. POST ADJUSTMENT 1. Post and upper saw guide height is regulated by the Post selector switch on the control panel. 2. Sawing results will generally be more satisfactory if the post and upper saw guide are kept as close as possible to the material being cut. Doing so helps reduce saw band vibration and contributes to more accurate sawing. The post can be lowered only when the saw head is fully retracted. When the saw head has been tilted, make sure the post and saw guide will clear the material and/or the vise jaws. 15

20 HEAD REVERSE RATE 1. Located on the left side of the control console, this valve is used to regulate the reversing speed of the saw head. Turn the knob counterclockwise to increase the reversing velocity; clockwise to decrease it. The valve s lower locking knob or set screw helps maintain the setting. 2. It can also be used to withdraw the saw band from its kerf during a binding or jamming situation To do so: (a) Turn the Band selector to "stop" if the saw band is stalled; (b) Turn the Feed selector to "auto-off"; (c) Turn the Head Reverse Rate knob clockwise to the minimum rate and move the Feed selector to "reverse". 3. Very gradually increase the head reversing rate by turning the control knob counterclockwise to allow the carriage to slowly retract and withdraw from its kerf. 2. When tilting the head to the left, the LCD will display the angle with a minus (-) sign in front of the value. When tilting to the right, there will be no sign in front of the value. Eliminate any electromagnetic radiation from such things as radio transmitters, walkietalkies, etc. which may affect the angle data shown on the display. ROLLER TABLE 1. Material is supported on the table by four (4) rollers on each side of the saw band. Rollers have sprockets and are chained together for ease of moving material into cutting position. Material movement is done by means of a hand crank (hand crank is also used for chip conveyor) that fits onto a fitting on the far right or far left roller. HEAD TILT ADJUSTMENTS 1. The saw head can be tilted up to 45 left or right for angular sawing and controlled by a selector switch on the pushbutton panel. Tilt angle is indicated by the Miter Meter, or on older machines, a protractor scale and pointer located on the rear right side of the roller table behind the sawing head. 2. The sawing head must be in the fully retacted position in order to tilt the head. (a) Turn the Operation selector to "set-up"; (b) Turn the Feed selector to "reverse" to fully retract the head; (c) Turn Tilt selector to "left" or "right" as desired and then turn to "hold" when desired angle is achieved as indicated on the Miter Meter, or the protractor scale and pointer. MITER METER When the saw head is tilted, make sure the post and upper saw guide is positioned to clear the material and/or vise jaws. Failure to do so will result in damage to the post. 1. This angle measuring devise is mounted to a bracket on the left side of the control console. The battery operated unit has a "power on" thumbwheel or button and a LCD readout window to display the tilt angle of the saw head. Roller Table. 2. Maximum table support weight is 6000 pounds ( kg) evenly distributed with no impact. VISE ADJUSTMENTS 1. The inch high (317.5 mm) vise jaws are mounted on the left side of the saw band and controlled by a selector switch on the pushbutton panel. 2. To adjust the movable jaw: (a) Lift up and hold the locking lever; (b) Slide both the vise jaw and vise lock toward the workpiece; (c) Locate the pin into the nearest hole in the vise slide bar by releasing the locking lever; (d) Turn the Vise selector switch to "close". 16

21 VISE ADJUSTMENTS (Continued...) 3. The fixed vise jaw distance from the saw band can be adjusted by: (a) Loosening the lock screw; (b) Slide the fixed vise to desired position; (c) Tighten the lock screw. Certain work-hardening materials will require a moderately heavy initial Band Feed valve setting to assure immediate penetration of blade teeth. Light feeds on these materials may cause the blade to slide over the stock resulting in saw band damage. Generally, top performance from a sharp saw band results from relatively low Band Feed valve settings. It will be necessary to increase the setting as the saw band becomes duller. This will help keep the cutting rate constant throughout the life of the saw band. Band feed adjustments are not necessary for changing stock cross-sections. A servo valve enables the saw band to maintain a uniform cutting rate. Reducing Cutting Rate & Band Speed for Pipe, Tubing and Structurals 1. Increasing loading per tooth occurs when sawing thin stock sections. Although the blade teeth can bear some overloading, a cutting rate reduction must be made. Movable Vise Jaw With Vise Lock. When the saw head is tilted, make sure the post and upper saw guide is positioned to clear the material and/or vise jaws. Failure to do so will result in damage to the post. BAND FEED ADJUSTMENTS 1. Band feed is the pressure exerted by the workpiece against the saw band's cutting edge. It is controlled hydraulically and regulated with the Band Feed valve. Turn the valve clockwise to "increase" pressure, counterclockwise to "decrease" it. The valve s lower locking knob or set screw helps maintain the setting. 2. The following are important factors to consider when setting or adjusting the Band Feed valve: Turn the Band Feed valve to a low setting if the correct band feed is not known. The operator can then increase or decrease pressure during operation to obtain the best cutting rate consistent with desired blade life and stock cut finish. Always be sure to take a good chip. Never start a cut with the maximum Band Feed valve setting. Blade damage may occur. 2. Proceed as follows when it becomes necessary to modify solid section sawing recommendations: (a) Measure the thinnest stock section to be cut; (b) Apply the corresponding percentage factor from the chart below; (c) Use a high band speed, but never exceed the maximum speed recommended for stock sections of the same size. SECTION THICKNESS FACTOR TO APPLY TO MINIMUM CUTTING RATES GIVEN BY JOB SELECTOR* Up to 3/16 inch 40% (0 to 4.8 mm) 3/16 to 3/8 inch 50% (4.8 to 9.5 mm) 3/8 to 5/8 inch 60% (9.5 to 15.9 mm) 5/8 to 1 inch &over 70% (15.9 to 25 mm & over) Cutting Rate to Thickness Relationship. *Based on 5 inch (127.0 mm) solids. 17

22 COOLANT SYSTEM Coolant Selection 1. The main cause of tooth failure during band machining is excessive heat build-up. Using the proper cutting fluid reduces the heat generated during operation. It also helps the machine take full advantage of its high-speed steel saw bands. Contact your DoALL sales representative for complete information about the use of coolants and their applications. Coolant Application 1. Coolant is applied as follows during sawing: A valve located below and left of the control panel regulates: (a) The flow to the saw band and cutting area through the saw guide inserts; (b) To a flushing nozzle for washing parts or cleaning areas of the machine. A valve located under the step on the left side of the machine base near the coolant pump regulates: (a) A nozzle for removing chips and cooling the band drive motor located below and to the right of the lower bandwheel; (b) A flushing nozzle to keep chips moving off the pan onto the chip conveyor. 2. Coolant flow is started by: (a) Pushing the Hydraulic Start button; (b) Turning the Coolant selector to "on" or "band on"; (c) Turning the coolant valves counterclockwise until fluid is flowing and completely shrouds the saw band. DO NOT start cutting until coolant is flowing adequately. Dry cutting will greatly reduce blade life. 3. The machine will function through a wide range of hydraulic fluid temperatures, although ideal temperature range is between 90 and 130 F. (32 and 55 C.). Machine functions may be sluggish if operated with fluid temperature below 70 F. (21 C.). 4. The operator should check the cutting rate closely as fluid temperature rises. Feed force changes will be necessary as the fluid warms. For example: If Feed Force is set to obtain a given cutting rate with fluid temperature at 50 F. (10 C.), the rate will increase substantially when fluid warms up to 100 F. (38 C.). CHIP REMOVAL 1. Metal chips should be removed from the work area as soon as possible. They can be washed or scraped into the right front pan opening, or scooped out with the supplied shovel-rake. Band Brush DO NOT shovel or rake chips while the saw band is running. 1. A band brush powered by the lower bandwheel and removes metal chips from the saw band. During machine operation, the brush bristles should be positioned so that the tips clean chips from the blade teeth gullets, but do not contact the bottom of the gullets. DO NOT allow metal chips to accumulate on the brush. 2. Metal chips removed by the band brush fall into the coolant reservoir. These should be removed frequently by turning the hand crank operated chip conveyor (hand crank is also used for roller table). 3. Drip pan capacity is 20 gallons (75.7 liters). HYDRAULIC SYSTEM 1. The hydraulic and band drive systems operate independently. This allows the operator to perform the following tasks while the band drive motor is not running: (a) Change saw bands; (b) Traverse the sawing head; (c) Clamp or unclamp the vises; (d) Position stock manually. 2. The machine's hydraulic reservoir has a 20 gallon (75.7 liter) capacity. Refer to the Lubrication section of this manual for recommended oils. Chip Removal Points. 18

23 CHIP REMOVAL (Continued...) Flushing Hose 1. Metal chips and other debris may accumulate over time around such machine areas as: saw guides, drive and idler bandwheels, vises, slides, feed and discharge areas, etc. 2. The operator should check often for metal chip collections which can adversely affect machine performance. They should be removed with the Flushing Hose as soon as possible. Band Wipers The DoALL Company recommends using the Flushing Hose to remove chips at least twice per each eight (8) hour shift, and more often with heavier use. 1. A wiper located at approximately the two (2) and ten (10) o'clock position from the lower bandwheel removes coolant residue from the moving saw band before it reaches the lower and upper bandwheels. 2. A set of wipers are also used to wipe the saw band before entering the cutting area. These wipers are located on top of the saw guide inserts on the upper saw guide block. Shovel-Rake 1. Accumulations of metal chips can be removed from the machine with the shovel-rake. DO NOT use the shovel-rake while the saw band is running. Combination Shovel-Rake. TYPICAL OPERATING PROCEDURES Manual Operation 1. These procedures assume that the following machine conditions exist: (a) The machine has been properly installed and aligned; (b) The band drive motor is off; (c) The proper saw band has been installed, is correctly tracked and tensioned; (d) All lubrication procedures have been carried out. 2. Push the Hydraulic Start button and turn the Operation selector to "set-up". Then: (a) Retract the sawing head completely by turning the Feed selector to "reverse" and then to "auto-off" when the head has reversed; (b) Turn the Vise selector (and Nesting Fixture(s) if supplied) to "open" and unclamp the vise; (c) Raise the post and saw guide by turning the Post selector to "up" and then to "hold" when the saw guide has been raised enough to clear the stock and/or vise; (d) Turn the Band selector to "stop". 3. Load the stock to be cut onto the roller table or use controls for the material handling equipment if supplied to move stock into position. 4. To move the stock into position for clamping by the vise jaws: (a) Turn the hand crank on the outside table roller until desired length is achieved; (b) Lift up and hold the locking lever; (c) Slide both the vise jaw and vise lock toward the workpiece; (d) Locate the pin into the nearest hole in the vise slide bar by releasing the locking lever; (e) Turn the Vise selector (and Nesting Fixture(s) if supplied) to "close".

28 MAINTENANCE It is strongly recommended that repair procedures be performed by experienced maintenance personnel, or a DoALL service representative who is trained to repair and service your machine. REPLACING SAW GUIDE AND BACK-UP INSERTS These instructions can be used to replace saw guide inserts and back-up inserts on both upper and lower saw guides. Note that the upper and lower saw guide inserts are NOT interchangable and care must be taken when ordering new ones. The band drive motor must NOT be running when replacing saw guides and back-up inserts. 1. Loosen the insert adjustment screw on each saw guide. Then: (a) Remove the saw band; (b) Remove the adjustment screw be very careful not to drop or lose the front insert when it falls from the assembly; (c) Loosen the screw and remove the rear insert. HYDRAULIC SYSTEM 1. Keep the reservoir filled at all times. Capacity is 20 gallons (75.7 liters). Check the reservoir oil level daily by referring to the sight gauge. 2. Drain, clean, refill the reservoir and change the oil filter after the first month of operation; every six (6) months thereafter. Clean the suction strainer and filler opening screen when necessary. Automatic transmission fluid is the recommended product. 3. Before changing the hydraulic fluid: (a) Retract the saw head completely; (b) Push the Stop button; (c) Remove the reservoir drain plug; (d) Allow the reservoir to drain completely. System Pressure 1. Hydraulic system pressure is correctly set at the factory and should not require adjustment for a considerable period of time. Correct system pressure is 1000 ±25 psi (68.9 ±1.7 bar.) 2. Pressure is adjusted by turning the screw extending outward from the hydraulic pump. Consult a DoALL representative if assistance is needed. Pump Repair & Replacement 1. DO NOT attempt to repair the hydraulic pump. Return it to the factory for repair or replacement. Be sure to specify the correct pump model and serial numbers when returning the unit. Typical Saw Guide Assembly. 2. Thoroughly clean the saw guide and inserts area. Then: (a) Reverse the carbide back-up insert (if worn); (b) Replace the rubber back-up insert if it has deteriorated (this will help prevent coolant leakage) (c) Check the condition of the belleville washers on the adjustment screws, replace if flattened. 3. Install the new inserts. Then: (a) Thread the adjusting screw inward part way; (b) Reinstall the saw band between the inserts; (c) Tighten the adjustment screw; (d) Back off the adjustment screw 1/4 turn. 2. Following a new pump installation: (a) Jog the Hydraulic Start and Stop buttons several times, on for two (2) seconds, off for three (3) seconds until the pump is primed; (b) Check for proper pump rotation while jogging; (c) Review wiring connections if the pump rotates in the wrong direction. Seals & Cups After the pump has been primed, run it for several minutes while operating the machine s controls to purge entrapped air from the pump and system. Check for oil leaks while the system is being operated. 1. Seals and cups used in DoALL hydraulic systems are compatible ONLY with hydraulic oils having an aniline point between 215 and 230 F. (102 and 111 C.). 24

29 HYDRAULIC SYSTEM (Continued...) 2. If hydraulic oil having an aniline point not falling within the above range is used, the seals may either swell or shrink and harden. This causes machine malfunction and leakage. DoALL hydraulic fluid with an aniline point of approximately 221 F. (106 C.) will not cause deterioration of component seals. COOLANT SYSTEM 1. The machine s coolant drip pan has a 20 gallon (75.7 liter) capacity. 2. Check the coolant often for signs of contamination or breakdown. The drip pan and coolant system should be drained and cleaned thoroughly when the cutting fluid becomes undesireable for further use. If another type of coolant is to be used, the entire coolant system must be flushed (use DoALL s Kleen Flush). Contact your DoALL sales representative for complete information about the use of coolants and their applications. MACHINE CLEANING 1. Keep the machine and its parts as clean as possible to prevent excessive wear and damage. 2. Use the Flushing Hose as soon as possible to remove metal chips and other waste materials which may collect around the saw guides, bandwheels, vises, slides, etc. The hose has a hand-operated valve and attaches to the coolant pump. The DoALL Company recommends using the Flushing Hose to remove chips at least twice per each eight (8) hour shift, and more often with heavier use. 3. Use the supplied shovel-rake to remove accumulated metal chips or other waste materials from machine areas. Be sure the band drive motor is stopped before opening machine doors or covers. MACHINE ALIGNMENT 1. Misalignment of the machine s saw guides, slide bar, saw band, pivot points, post, etc., will cause inaccurate sawing. DO NOT attempt any alignment procedures not covered by this manual. Contact a DoALL service representative in such cases because special fixtures and techniques may be required. BRUSH ADJUSTMENTS Band Brush 1. The band brush will wear and lose steel bristles over time. Check often to be sure the bristles are removing metal chips from the blade tooth gullets, but are not touching the bottom of the gullets. 2. Move the brush closer to the blade as normal wear occurs. Replace the brushes when necessary. Band Wipers 1. Band wipers, located at approximately the ten (10) and two (2) o'clock positions from the lower bandwheel, remove coolant residue from the moving saw band before it reaches the upper and lower bandwheel. Adjust or replace the wipers when necessary. WEAR PLATE REPLACEMENT 1. The removeable vise jaw and vise bed wear plates must be replaced before excessive wear causes the mounting screw heads to become damaged and makes removal difficult. Vise Jaw Plates 1. The machine has one(1) vise jaw wear plate on each jaw. All wear plates are mounted with low-head screws. Be sure the vise jaws are separated and the machine turned off before trying to replace the wear plates. Vise Bed Combination Shovel-Rake. 1. There is one (1) vise bed wear plate on each side of the saw band. All wear plates are mounted with low-head screws. 25
