PERSONAL INJURIES CAN OCCUR. BEFORE PERFORMING ANY MAINTENANCE OR REPAIR, UNPLUG THE COMPRESSOR AND BLEED OFF ALL AIR PRESSURE. To ensure efficient operation and longer life of the air compressor unit, a routine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to a unit in a normal working environment operating on a daily basis. If necessary, the schedule should be modified to suit the conditions under which your compressor is used. The modifications will depend upon the hours of operation and the working environment. Compressor units in an extremely dirty and/or hostile environment will require a greater frequency of all maintenance checks. 1. Drain water from the air tank, any moisture separators or transformers. 2. Check for any unusual noise and/or vibration. 3. Manually check all safety valves to make sure they are operating properly. 4. Inspect air filter, replace if necessary. 5. Inspect air lines and fittings for leaks; correct as necessary. Each year of operation or if a problem is suspected: • Check condition of air compressor pump intake and exhaust valves. • Check condition of check valve. Replace if damaged or worn out. Filling with Oil: 1.Remove the oil filler plug. 2.Slowly pour the proper oil into the pump crankcase. 3.Always keep oil level in the middle of the sight glass. Changing the Oil: Note: Every 300 hours or 3 months, whichever comes first. 1.Remove the oil drain plug. COLD WEATHER CONDITIONS: AMBIENT TEMPERATURES AT POINT OF OPERATION SAE VISCOSITY ISO VISCOSITY -16°C TO 0°C (3.2°F - 32°F) SAE 10W ISO 32 1°C TO 26°C (33.8°F - 78.8°F) SAE 20W ISO 68 ABOVE 27°C (80.6°F) SAE 30W ISO 100 Page 12 Allow oil to drain completely. 2.Replace the oil drain plug (The use of a sealing compound or Teflon tape to avoid leakage is recommended.) 3.Refill with the recommended oil to the proper level. SERVICE INSTRUCTIONS Air Filter - Inspection and Replacement: • Keep the air filter clean at all times. Do not operate the compressor with the air filter removed. • 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, check and replace the filter element. WARNING: SAFETY VALVE – INSPECTION IF THE SAFETY VALVE DOES NOT WORK PROPERLY, OVERPRESSURIZATION MAY OCCUR, CAUSING AIR TANK RUPTURE OR AN EXPLOSION. OCCASIONALLY 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. Units with External Brass Check Valve Replacement 1. Release all air pressure from air tank and unplug outfit. 2. Remove shroud. 3. Loosen the top and bottom nut of the outlet tube and remove. 4. Remove the pressure release tube and fitting. 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 suitable solvent. 7. Apply 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. Motor The motor has a manual reset thermal overload protector switch. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before resetting the overload switch and restarting. If the overload protector shuts the motor off frequently, check for a possible voltage problem. Low voltage can also be suspected when: 1. The motor does not get up to full power or speed. 2. Fuses blow out when starting the motor; lights dim and remain dim when motor is started and is running.
