The belt guard should be removed only when the air compressor power is disconnected. 1. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank. 2. Remove the belt guard. 3. Mark pump position on saddle. 4. Loosen the motor mounting screws and slide the motor toward the air compressor. 5. Remove the belt and replace with a new one. 6. See the "Adjust Belt Tension" before tightening motor mounting screws. Adjusting Belt Tension 1. Slide motor into original position, line the motor up with the mark made earlier on saddle. 2. Tighten two outside motor mounting screws enough to hold the motor in place for checking pulley and flywheel alignment. 3. The belt should deflect 3/16" at midway between the pulley and the flywheel when a 5-10 pound weight is applied at the midway point. Downward Force Deflection 3. When proper belt tension is achieved, tighten all four motor mounting screws. See Parts manual for torque specifications. NOTE: Once the engine pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16" to prevent excessive belt wear. Verify the alignment by performing the following Pulley and Flywheel Alignment. D27042 18-ENG Motor Pulley/Flywheel Alignment NOTE: Once the motor pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16" to prevent excessive belt wear. The air compressor flywheel and motor pulley must be in-line (in the same plane) within 1/16" to assure belt retention within flywheel belt grooves. To check alignment, perform the following steps: 1. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank. 2. Remove belt guard. 3. Place a straightedge against the outside of the flywheel and the motor drive pulley. 4. Measure the distance between the edge of the belt and the straightedge at points A1 and A2 in figure. The difference between measurements should be no more than 1/16". 5. If the difference is greater than 1/16" loosen the set screw holding the motor drive pulley to the shaft and adjust the pulley’s position on the shaft until the A1 and A2 measurements are within 1/16" of each other. 6. Tighten the motor drive pulley set screw. See Parts manual for torque specifications. 7. Visually inspect the motor drive pulley to verify that it is perpendicular to the drive motor shaft. Points B1 and B2 of Figure should appear to be equal. If they are not, loosen the setscrew of the motor drive pulley and equalize B1 and B2, using care not to disturb the belt alignment performed in step 2. 8. Retighten the motor drive pulley setscrew. See Parts manual for torque specifications. 9. Reinstall belt guard. Air Compressor Pump Intake and Exhaust Valves Once a year have a Trained Service Technician check the air compressor pump intake and exhaust valves. Inspect Air Lines and Fittings for Leaks 1. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank. 2. Apply a soap solution to all air line fittings and connections/piping. 3. Correct any leaks found. IMPORTANT: Even minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance. Air compressor Head Bolts Torquing The air compressor pump head bolts should be kept properly torqued. Check the torques of the head bolts after the first five hours of operation. Retighten if necessary. See Parts manual for torque specifications. 19-ENG D27042 SERVICE AND ADJUSTMENTS ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE PERFORMED BY TRAINED SERVICE TECHNICIAN. Risk of Unsafe Operation. Unit cycles automatically when power is on. When servicing, you may be exposed to voltage sources, compressed air, or moving parts. Before servicing unit unplug or disconnect electrical supply to the air compressor, bleed tank of pressure, and allow the air compressor to cool. To Replace or Clean Check Valve 1. Release all air pressure from air tank. See "To Drain Tank" in the Maintenance section. 2. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank. 3. Using an adjustable wrench loosen outlet tube nut at air tank and pump. Carefully move outlet tube away from check valve. 4. Using an adjustable wrench loosen pressure relief tube nut at air tank and pressure switch. Carefully move pressure relief tube away from check valve. 5. Unscrew the check valve (turn counterclockwise) using a 7/8" open end wrench. Note the orientation for reassembly. 6. Using a screwdriver, carefully push the valve disc up and down. NOTE: The valve disc should move freely up and down on a spring which holds the valve disc in the closed position, if not the check valve needs to be cleaned or replaced. In closed position disc is visible. In open position nothing is visible. Screwdriver 7. Clean or replace the check valve. A solvent, such as paint or ...
