See wiring diagram included with machine for conversion to 230V. For international use, a 50 Hertz, single phase motor is available. Installation of Accessories 1. Loading Tables - mount the 39-1/4 inch (1m) table to the front (Figure 1, ), the 19-3/4 inch (0.5m) exit table to the back (Figure 1, ). Tighten brace bolts so that the tables are perpendicular to the machine frames. The roller bars and edge guides (Figure 1, ) will fit their respective tables only. Figure 3: Sign Blank on Conveyor Table Foot Conveyor Tables - assemble tables and set in line with the roller tables of the machine. Adjust conveyor table height to equal roller table height. 2

3 3. Collar Roller Assembly - if extrusions or "Extra-Sheet" panels are to be run, the bottom roller must be replaced with this accessory (Figure 4). To remove the bottom roller: a. Raise top roller to maximum clearance by turning hand wheel (Figure 2). Lower bottom roller by moving release level (Figure 5, ) to "Lower" position. b. Remove drive chain (Figure 6, ) from bottom roller sprocket by loosening the bolts on idler-sprocket mounting (Figure 6, ) and giving full slack to chain. Remove safety guard plates. assembly RAA-2 must be used in place of the lower rubber roll on the 48" ISRA. To properly support the Extrusheet panels two sizes of collars are required. The 1" wide collars are placed at each rib and the 2" collars are placed between ribs (see schematic below). The 1" wide collar's diameter is.085" less than the 2" wide collar and allows for the rib thickness. If the panel is not uniformly supported, particularly at the ribs, the sheeting may lift in the unsupported areas. Shops working with Extrusheet should obtain and install the correct number of collars for the sheeting widths they anticipate handling (24" wide required four 1" collar and 36" requires five). Figure 4: Collar Roller Assembly for Extrusions c. Lift out bottom roller. This is most easily accomplished by setting a metal bar or wooden beam under roller ends, carefully prying out roller, lifting at both ends. d. Collar roller assembly is furnished with its own bearings and sprocket. Both bearing blocks on the ends of the extrusion shaft must be inserted flat side down. Insert collar roller and replace drive chain. Move release lever (Figure 5, ) to its "Raised" position, take up chain slack, and tighten the bolts on the idler sprocket mounting (Figure 6, ). IMPORTANT: Adjust drive chain tension only when extrusion shaft (or bottom roller) is in the "Raised" position. e. Check collar roller alignment. See Alignment section. Replace safety guard plates. f. Application of reflective sheeting on Extrusheet panels. The collared roll Figure 5: Bottom Roller Release Lever 3

4 Figure 6: Drive Chain 4. Edge Roller Assembly (Figure 7) - assemble, center in line with exit table at back of machine and bolt securely to exit table frame. Use of commercial type heat guns is recommended to assist sheeting application of extruded panels. Attach heat guns 1 to frame as shown, aimed to eliminate sheet fold resistance at the first edge roller and provide heat along the line of edge rollers. See IF 1.4 for details of operation. Alignment WARNING: The heater does not have to be HOT to cause injury. Under no circumstances should the heater element be touched, even when cold, unless the electrical power is disconnected. Moisture can cause the heater element to carry an electrical charge up to 200V. A. Bottom Roller: 1. The bottom roller is the base roller from which other rollers are positioned. It must be aligned parallel to the stock and liner mandrels. To check alignment of the bottom roller, move the bottom roller with the release lever (Figure 5, ) into the "Raise" position. Raise top roller to remove pressure between rollers. With a steel tape, measure around the liner mandrel, bottom roller, and stock mandrel on both sides of the machine. The tape should be placed 4 inches to 6 inches (10-15cm) in from the bottom roller ends and encircle only the roller and mandrels (see Figure 10). This measurement should not differ more than 1/32 inch (0.08cm) on either side of the machine. Item 4 Item 5 Figure 7: Edge Roller Assembly 1 Available in commercial supply catalogs such as "Grainger Supply." Typical is Master Heat Gun Model F 12 Amp Master Appliance. 4 Figure 8: Heater Control Arm

5 Figure 8A: Tension and Heater Adjustment Figure 11: Leveling Knob and Speed Crank Figure 9: Edge Roller Assembly 2. If measurement indicates that alignment is required, adjust bottom roller leveling knobs (Figure 11, ). Ensure that bottom roller is 1/16 inch (0.16cm) above top of feed table rollers. To adjust knobs, loosen lock nuts with accessory wrench provided. One full turn will change roller position approximately 1/16 inch (0.16cm). After adjustment, tighten lock nuts. Repeat A1 above. Check the drive chain tension (Figure 6, ). Adjust as needed. Figure 12: Top Roller Lock Nuts B. Top Roller: 1. Vertical Alignment The top roller should be checked for vertical alignment with the bottom roller. With the bottom roller in its raised position, turn the hand wheel (Figure 2) to position the top roller close to but not in contact with the bottom roller. Place a short spirit level vertically against the faces of the two rollers (Figure 13). Figure 10: Measure for Roller Alignment 5

6 Figure 13: Roller Alignment Check for consistent alignment at each end with the level. If adjustment is required, SLIGHTLY loosen the retaining bolts of the top roller bearing blocks. The slotted bearing blocks will allow lateral movement. Do not allow the bearing blocks to move when bolts are retightened. Recheck bottom roller alignment as described in Section A. 2. Horizontal Alignment Ensure that the bottom roller release lever (Figure 5, ) is in raised and locked position. Turn hand wheel (Figure 2) until top roller almost touches bottom roller. Check visually for an even aperture between the rollers. If adjustment is required, the top roller lock nuts (Figure 12, ) must be repositioned on one side of the machine. Separate the lock nuts on one side and screw the lower nuts downward to raise OR upward to lower that side of the roller. Tighten the lock nuts against each other. Recheck for even aperture as above. If finer adjustment is needed, repeat above procedure. When properly aligned, tighten the lock nuts. 3. Preload Spring Adjustment The top roller pressure is equalized by adjusting the preload springs (Figure 15, ) on either side of the machine. To adjust, loosen lock nut under pressure setting hand wheel (Figure 15, Item 1) and turn wheel with pin (Figure 15, ) in place to adjust far spring*. Remove pin from hole and turn wheel to adjust near spring, while holding the top roller hand wheel (Figure 2) stationary. Adjust both springs equally to 2-7/8 inches to 3 inches (7.3cm-7.6cm) (Figure 15, ) measured from bottom of metal brace to top of chain sprocket. To check for even tension, obtain two strips of inch aluminum approximately 3 inches x 10 inches (5cm x 25cm) in size. *Always adjust the far spring first since this adjustment will affect the near spring tension; the near spring can be adjusted independently as final adjustment. Place the two strips in the nip approximately 6 inches (15cm) from each end (Figure 14). Turn hand wheel until top roller rests firmly on the aluminum strips. Wearing gloves, grasp one aluminum strip in each hand and at the same time work the aluminum from side to side to feel the grip of the rollers. If aluminum strips cannot be moved, turn the hand wheel sufficiently to allow slight movement of aluminum. If one side feels tight adjust the near spring (Figure 15, ) until uniform tension is achieved on both sides. Figure 14: Roller Pressure Adjustment Figure 15: Preload Spring Adjustment 6

7 Re-insert pin through sprocket and into nearest hold in pressure setting hand wheel (four holes are inside hand wheel). Retighten lock nut. C. The Heater (Figure 8, ) can be directed at the sheeting or the substrate. When positioned towards the sheeting, the heater should be adjusted so that a perpendicular to the heating elements will be aimed just above the nip (Figure 8A). In this position the heater control arm actuates a microswitch (Figure 8, ) that starts the drive motor. 1. To adjust, loosen the two set-screws on the collar that holds the bottom sprocket (Figure 8, Item 5). Lower the heater arm (Figure 8, Item 4) until microswitch (Figure 8, ) is contacted, then reaim heater by hand until it's aimed as shown in Figure 8A. Retighten set screws. 2. To warm sign blanks, the heater may be turned to aim straight down on the blanks at a point just before they pass into the nip of the rollers. D. Stock and Liner Mandrel Lateral Adjustments (Figure 16, Items 3 and 4): Item 9 Item 8 (Springs Concealed) Figure 17: Pressure Knob E. Stripper Roller: 1. The springs mounted in the frame at each end of the stripper roller (Figure 17, ) provide pressure on the roller. 2. Turn pressure setting knob (Figure 17, ) on each end of roller to expose 1-1/16 inch (2.7cm) screw thread. 3. With the stripper roller in its raised position, a uniform gap should be visible between the upper roller and the stripper roller. Item 5 0 (Inside Adjustment Knob Shaft) Item 6 (Inside Adjustment Knob Shaft) Item 4 Item 7 Figure 16: Stock and Liner Mandrel Figure 18: Hand Wheel Adjustment 1. These mandrels should initially be centered laterally by turning lateral adjustment knobs (Figure 16, Items 3 and 4). 2. Keep set-screws (Figure 18) tightened to prevent adjustment knobs from moving during operation. 7 F. Stock Roll Brake Adjustment: The brake (Figure 16, Item 7) regulates tension. Sheeting must be applied at minimum tension. Adjustment to reduce tension must be made during operation as stock roll diameter decreases. See IF 1.4.

8 G. Clutch: The clutch on the liner mandrel controls the liner wind up tension. Check for proper clutch adjustment by firmly grasping liner mandrel (Figure 16, ) with one hand and rotating; the mandrel should rotate with slight resistance. If adjustment is necessary, loosen set screw (Figure 6) with Allen wrench. Adjust hexagonal nut to achieve proper resistance, and retighten setscrew. H. Chain Tension: Adjust chain tension only when the bottom roller is locked in the raised position. I. Production Speed: NOTE: MACHINE MUST BE RUN- NING TO CHANGE SPEED. Determine speed by running a sign blank of known length through rubber rollers. Adjust speed crank (Figure 11, ) accordingly. For example: A 4 foot (1.2m) blank passing through the rollers requires 20 seconds to achieve 12 feet (3.6m) per minute. Applicator Maintenance A. Periodically check applicator condition and alignment, particularly if the machine has been used extensively. B. Check rubber rollers for wear with a straight edge. If low spots or worn areas are observed, replace the rollers or have them professionally resurfaced. Check the bearings on all rollers and replace any that are worn. C. Lubrication 1. Reeves Moto-Drive (Diagram No. 1) - Some types and grades of lubricants suitable for the moto-drive are: Socony-Mobiltemp No. 1 Texaco Novatex No. 1 American Oil Co. Amolith Grease No. 1 Shell Alvania No. 1 Humble Oil Co. Grease No a. Lubricate sliding discs at not less than 2 week intervals. Apply two or three effective grease gun strokes to lubricate fittings at points A & B. Diagram No. 1 Moto-Drive Lubrication Points b. The frame bearings on the variable speed shaft and thrust bearing on constant speed disc assembly are prelubricated; they require no further lubrication. c. Lubricate motor bearings at points E, when plugs are provided, in accordance with users general plant practice for lubricating ball bearings or at least once each six months; 1/2 inch of grease is sufficient. Plugs must be removed and lubrication fittings installed to apply lubricant. d. Lubrication information is also provided on the moto-drive nameplate. 2. Right Angle Reducer a. Lubricate right angle reducer with Gulf Oil Co., Trans Gear Lube, 140, or Shell Oil Co. Spirex Heavy Duty, 140. b. Lubricant should be drained and the gear case refilled every 750 hours of normal daily use; every 500 hours if operated continuously or in high temperatures. c. When changing lubricant in the reducers, use a good grade of ball bearing grease. Do not over lubricate grease packed bearings. 3. General a. Periodically grease roller bearings. Do not use silicone based lubricants. b. All moving parts, including threaded adjustment rods, should be lubricated at points of contact with light grade machine oil. 8

9 D. Parts/Service 1. ( ) for service centers of Reliance electric motor and Reeves drives. E. Bottom Roller Cleaning 1. To remove adhered scrap sheeting, use the heater to soften the material. Carefully remove sheeting with a slightly sharpened spatula. Use extreme care to avoid damage to the rubber. 2. Use a solvent such as xylol, heptane, VM&P Naphtha to remove adhesive residue. Give the solvent time to work. DO NOT USE THE HEATER WHILE WORKING WITH SOLVENTS. 3. To prevent sheeting from adhering to the bottom roller, wrap paper from Engineer Grade sheeting or SCW-568 slipsheeting around the roller with the glossy side facing out. Tape the paper in place with Scotch Tape #853 or #8401. The liner or slipsheet should form a smooth wrinkle-free cover but it may wrinkle or tear from the roller if the rotation direction is reversed. 4. DO NOT USE SILICONE SPRAY IN SHOP AREA WHERE APPLICA- TION OR SCREEN PROCESSING IS PERFORMED. SILICONE CAN CAUSE NON-WETS IN SCREEN- ING. F. Periodically check CAL101 Heater Aim.
