Remove the wheel guard (Ref No 76) by removing thumb knobs (Key No 49) Whenever adjusting or replacing any parts on the sander turn switch "OFF" and remove plug from power source Remove belt table (Key No 59) by removing socket head bolt (Key No 52) Recheck table locking nuts and bolts. They must be tightened securely Make sure all guards are properly attached All guards should be fastened securely Make sure all moving parts are free and clear of any interference; With power disconnected, test operation by hand for clearance and adjust if necessary. Make sure abrasive belt always tracks properly; Correct tracking gives optimum performance After turning switch "On" always allow the belt to come up to full speed before sanding or grinding Keep your hands clear of abrasive belt, disc and all moving parts For optimum performance do not stall motor or reduce belt speed; Do not force the work into the abrasive BELT Release the tension on the belt by pulling the tension handle (Key No 65) forward (towards operator) Remove belt from the top wheel (tracking wheel, Key No. 72) release the tension handle and remove belt Install abrasive belt in the reverse manner Place the abrasive belt squarely on the wheels spring action will tension the belt. Make sure the belt is tracking correctly tracking if necessary The arrow should point down toward the belt table to ensure that the splice in the belt will not come apart When the belt is tracking properly it rides squarely on the center of each wheel Replace the wheel guard and belt table Replace abrasives when they become loaded (glazed) or frayed Remove the wheel guard Never attempt wet cutting If the workpiece becomes too trot to handle, cool it in cold water. Always wear eye protection or face shield WEAR YOUR Adjust the The abrasive belt has an arrow printed on the inside which indicates the direction of travel Never push a sharp corner of the workpiece rapidly against the belt or disc; The abrasive may tear When grinding metal: Move the workpiece across the abrasive, to prevent built up heat The TRACKING ABRASIVE BELT Test the tracking Plug in power cord Turn the switch "ON" and immediately "OFF' If the abrasive belt did not move to the right or left, it is tracking properly If the belt moved to the right or left, adjust the tracking To adjust the tracking wheel loosen the lock-nut (Key No 4), Use a 3mm setscrew wrench (Key No 21) to turn the tracking adjusting screw (Key No 63) If the abrasive belt moves to the right, tilt the top of the tracking wheel towards the frame by turning the adjusting screw clockwise TENSIONING ABRASIVE BELT Tension is created by a spring loaded cam shaft The tracking wheel is mounted on the opposite side of the shaft The spring return is transmitted to the tracking wheel and maintains the tension If the abrasive belt moves to the left, tilt the top of the tracking wheel away form the frame by turning the adjusting screw counter-clockwise Lock the position when the belt is tracking properly; so the belt will remain centered on the wheels. Hold the position of the tracking adjustment screw with the 3mm setscrew wrench Tighten Iocknut (Key No 64) to lock the position Replace wheel guard and secure with thumb knobs ADJUSTING BELT TABLE ANGLE To adjust the angle of the belt table, loosen the socket head bolt (Key No 52) and adjust to the desired angle Use a combination square to set the belt table at 45 ° or 90 ° to the abrasive belt Adjust for 1/16" clearance between the belt and the table When the belt table is at the desired angle, lock it into position by securely tightening the socket head bolt ABRASIVE Figure 5 BELT FINISHING REPLACING THE ABRASIVE DISC. The abrasiye belt can be used to sand wood, deburr metal, or polish plastic and glass The belt is most efficient when used with the table The 1" belt size is convenient for getting into corners and concave curved edges ADJUSTING BELT PLATEN Operating with the belt platen in place will allow the operator to sand or grind straight even lines Belt edges should be even with platen edges, (Key No 58) To adjust belt platen, loosen two each 1/4-20 X 5/8" hex head bolts (Key No,67) and adjust Tighten bolts securely POLISHING Remove disc table (Key Na15) Remove old abrasive disc by peeling it from the aluminum disc Removing aluminum disc from motor shaft is not necessary. Clean aluminum disc if necessary Select the proper abrasive disc and apply to ah_minum disc. The abrasive used can be changed to a different grit without replacing the abrasive disc. Additional aluminum discs are available (see recommended acessories) use separate aluminum disc for each grit size use& Interchange the aluminum disc to change grit size (see assembly page 7) AND CONTOUR SANDING: Remove platen completely, remove hex head bolts and washers (Key Nos 57, 3 & 30) Replace disc table ADJUSTING The belt has'ho rigid back and is able to follow the contour of curved parts Move the workpiece against the belt The belt will follow the contour (See Figure 4) DISC TABLE ANGLE The disc table is adjustable from 45 ° to 90 ° for beveled work To adjust the disc table, loosen the two socket head bolts and nuts (Key Nos. 17 & 7) and adjust to the desired angle Use a combination square to set the disc table at 45 ° or 90 ° to the abrasive disc When disc table is at desired angle, lock it into position by securely tightening the socket head bolts. ABRASIVE Abrasive disc sanding is well suited for finishing small end surfaces and convex curved edges Figure 4 SHARPENING: Move the workpiece across the "down side" (Right) of the face of the abrasive disc Adjust belt table to the desired sharpening angle and tighten securely Use the belt sander to notch the back of an auxiliary piece of wood Using a "C" clamp, attach the auxiliary piece of wood to the table, it acts as a support while sharpening (See Figure 5) Top edge of the wood should be approximately frnm _bra_iv_ h_,lt DISC FINISHING 1/16" The abrasive disc produces almost no abrasive action at the center. The abrasive disc moves fastest and removes more material at the outer edge If workpiece is fed without additional guidance, more material will be removed towards the outer edge of the disc. Fnr _r',"ura,"v i,_e the miter nm_ne USING THE MITER GUAGE The miter gauge is used only on the disc table. Use the miter gauge for securing work and holding the pro* per angle, while disc sanding Adjust the angle by repositioning the miter gauge scale (Key No 29) and locking it into place with thumbscrew and flatwasher (Key Nos 31 & 30). Check the accuracy of the miterguage scale, Use a combination square to adjust the miter gauge square to the face of the disc. Indicator (Key No 32) should be at zero, Loosen screw (Key No24) and reposition indicator if necessary DUST COLLECTION: The wheel cover has a I 1/4" diametel: exaust port in it The exhaust port will accept a standard 1 1/4" Dust collection hose. Use the exhaust port to connect the belt and disc sander to a shop vac or dust collector, RECOMMENDED ACCESSORIES ABRASIVE BELTS 1" x 42" FINE .....................................

LUBRICATION The shielded ball bearings in this sander are permanently lubricated at the factory, they require no further lubrication. CLEANING Keep machine and workshop clean. Do not allow sawdust to accumulate on the belt and disc sander_ Keep the wheels clean, Dirt on wheels will cause poor tracking and belt slippage. Operate sander/grinder with dust collector to keep dust from accumulating IMPORTANT: AFTER SANDING WOOD OR NONMETALLIC MATERIAL, ALWAYS CLEAN DUST COLLECTOR AND WHEEL GUARD OF SAWDUST BEFORE GRINDING METAL THE SPARKS COULD IGNITE THE DEBRIS AND CAUSE A FIRE Be certain motor is kept clean and is frequently vacuumed or blown free of any dirL Unpainted surfaces should be cleaned with penetrating oil. Use soap and water to clean painted parts, rubber parts and plastic guards. A small amount of machine oil can be applied to the cam shaft (Key No 62) within the tracking bracket° When operation seems stiff, a coat of automobile-type wax applied to the belt table and disc table will make it easier to feed the work while finishing. Do not apply wax to the belt platen, the belt could pick up the wax and deposit it on the wheels, causing the belt to slip. KEEP SANDER IN REPAIR *."
