The following routine maintenance schedule is geared to an outfit 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 outfits in an extremely dirty and/or hostile environment will require a greater frequency of all maintenance checks. ROUTINE MAINTENANCE SCHEDULE Daily: 1. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring. 2. Drain water from the air tank, any moisture separators, or transformers. 3. Check for any unusual noise and/or vibration. 4. Manually check safety valve to make sure of proper operation. 5. Inspect air filter and replace if necessary. 6. Inspect air lines and fittings for leaks and correct as necessary. 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. SERVICE INSTRUCTIONS 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. 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 wash it with mild detergent and warm water, or replace it. Fig. 4 Safety Valve - Inspection IF THE SAFETY VALVE DOES NOT WORK PROPERLY, OVER-PRESSURIZATION MAY OCCUR, CAUSING AIR TANK RUPTURE OR AN EXPLOSION. DAILY 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. 11-ENG Check Valve Replacement 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 and fitting. 5. Unscrew the check valve 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 strong solvent. 7. Apply sealant to the check valve threads. Reinstall the check valve. 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 an automatic reset thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. The compressor will automatically restart after the motor cools. 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/or is running. Motor - Wiring Diagram The motor connection diagram is located on the side of motor. STORAGE Before you store the air compressor, make sure you do the following: 1. Review the "Maintenance" section on the preceding pages and perform scheduled maintenance as necessary. 2. Set the “ON/AUTO” lever to “OFF”. 3. Turn the regulator counterclockwise and set the outlet pressure to zero. 4. Remove the air tool or accessory. 5. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring. 6. Drain water from air tank by opening drain cock valve on bottom of tank. WATER WILL CONDENSE IN THE AIR TANK. IF NOT DRAINED, WATER WILL CORRODE AND WEAKEN THE AIR TANK CAUSING A RISK OF AIR TANK RUPTURE. 7. After the water has been drained, close the drain cock or drain valve. NOTE If drain cock valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled. 8. Protect the electrical cord and air hose from damage (such as being stepped on or run over). Wind them loosely around the compressor handle. (If so equipped) Store the air compressor in a clean and dry location. 12-ENG TROUBLESHOOTING GUIDE PERFORMING REPAIRS MAY EXPOSE VOLTAGE SOURCES, MOVING PARTS OR COMPRESSED AIR SOURCES.
