WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO VOLTAGE SOURCES, COMPRESSED AIR OR MOVING PARTS. PERSONAL INJURIES CAN OCCUR. BEFORE PERFORMING ANY MAINTENANCE OR REPAIR, UNPLUG THE COMPRESSOR AND BLEED OFF ALL AIR PRESSURE. ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE DONE BY A QUALIFIED SERVICE TECHNICIAN. Routine Maintenance Schedule Daily: 1. Check oil level. Add if necessary. 2. Drain water from the air tank, any moisture separators or transformers. 3. Check for any unusual noise and/or vibration. 4. Manually check all safety valves to make sure they are operating properly. 5. Inspect for oil leaks and repair any leaks found. 6. Inspect air filter, replace if necessary. Every 40 Hours of Operation: 1. Clean and inspect the air intake filter; replace if necesssary. 2. Inspect condition of drive belt; replace if necessary. Every 100 Hours of Operation: 1. Drain and refill compressor crankcase with 16 fluid ounces (473.2 ml) of clean compressor such as Sears 9-16426 or SAE 20-20W SF motor oil 2. Increase frequency of oil changes if humidity or operating conditions are extreme. Every 160 Hours of Operation: 1. Check drive belt tension; adjust if necessary. (Refer to SERVICE INSTRUCTIONS in this manual.) 2. Inspect air lines and fittings for leaks; correct as necessary. 3. Check the alignment of the motor pulley to the flywheel. If necessary, align to within 1/32 inch on centerline. Each Year of Operation or if a Problem is Suspected: Check condition of air compressor pump intake and exhaust valves. Replace if damaged or worn out. Air Filter - Inspection and Replacement Hot surfaces. Risk of burn. Compressor heads are exposed when filter cover is removed. Allow compressor to cool prior to servicing. A dirty air filter will not allow the compressor to operate at full capacity. Before you use the compressor, check the air filter to be sure it is clean. If it is dirty, replace it with a new filter. On some models, the filter may be removed by using a pair of needle nosed pliers or a screwdriver. Pull or pry out the old filter. Push in the new air filter. Other models require removal of the belt guard and/or filter retainer. Check Valve Cleaning - Replacement Risk of personal injury. Manifold assembly contains compressed air which can be hazardous. Manifold gets hot during operation. Before servicing: • Unplug or disconnect electrical supply to compressor. • Bleed tank of pressure. • Allow compressor to cool. 1. Release all air pressure from air tank and unplug outfit. 2. Remove shroud. 3. Loosen the top and bottom nuts and remove the outlet tube. 4. Remove the pressure release tube, fitting, and connector. 5. Unscrew the check valve (turn counterclockwise) using a socket wrench. 6. Check that the valve disc moves freely inside the check valve and that the spring holds the disc in the upper, closed position. The check valve may be cleaned with a solvent, such as paint and varnish remover. 7. Apply a Teflon based pipe sealant to the check valve threads. Reinstall the check valve (turn clockwise). 8. Replace the pressure release tube and fitting. 9. Replace the outlet tube and tighten top and bottom nuts. 10. Replace the shroud. Safety Valve - Inspection If the safety valve does not work properly, over-pressurization may occur, causing air tank rupture or an explosion. Before starting compressor, pull the ring on the safety valve to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, it must be replaced with the same type of valve.

Release all air tank pressure. 2. On one-piece belt guards, remove the two beltguard screws on the bottom front of the outfit. 3. On two-peice belt guards, remove the front of the belt guard by disengaging the snaps. Insert a flat bladed screwdriver at each snap location and pry the beltguard apart. Replace Belt 1. Unplug compressor. 2. Remove (one-piece) beltguard, or front of (twopiece) beltguard as described above. NOTE Loosen the wing nut at the hold down plate.
