  • GENERAL MAINTENANCE NOTES

  • MOTOR LUBRICATION: Long time satisfactory operation of an electric motor depends in large measure on proper lubrication of the bearings. Bearing grease will lose its lubricating ability over time, not suddenly. Refer to the motor manufacturer’s instructions for the type of grease and lubrication intervals.

  • PRESSURE RELIEF VALVE: The pressure relief valve is an automatic pop valve. Each valve is properly adjusted for the maximum pressure of the unit on which it is installed. If it should pop, it will be necessary to drain all the air out of the tank in order to reseat properly, or drop pressure in line. Do not readjust.

  • TANK DRAIN VALVE: Drain valve is located at bottom of tank. Open drain valve daily to drain condensation. Do not open drain valve if tank pressure exceeds 25 psig. The automatic tank drain equipped compressor requires draining manually once a week.

  • PRESSURE SWITCH: The pressure switch is automatic and will start compressor at the low pressure and stop when the maximum pressure is reached. It is adjusted to start and stop compressor at the proper pressure for the unit on which it is installed. Do not readjust.

  • COMPRESSOR VALVES: If compressor fails to pump air or seems slow in filling up tank, disconnect unit from power source, remove valves and examine. Should damage be found to the valve reeds, complete valve must be replaced. Care must be taken that valves are replaced in exactly the same position and all joints must be tight or the compressor will not function properly. When all valves are replaced and connections tight, close hand valve at tank outlet for the final test. Valve gaskets should be replaced each

  • CHECK VALVE: The check valve closes when the compressor stops operating, preventing air from flowing out of the tank through the unloader solenoid valve. After the compressor stops operating, if air continues to escape through the unloader solenoid valve, it is an indication that the check valve is leaking. This can be corrected by removing check valve and cleaning disc and seat. If check valve disc is worn badly, replace same.

  • THE INTERSTAGE PRESSURE RELIEF VALVE on two stage compressors is provided to protect against interstage over pressure and is factory set to maximum pressure of 75 PSIG.

  • BELTS: Drive belts must be kept tight enough to prevent slipping. If belts slip or squeak, see V-belt maintenance in preceding section.

  • MAINTENANCE PROCEDURES

  • REPLACEMENT OF COMPRESSOR & GUIDE RINGS – The procedure for disassembly and reassembly is as follows:

  • REPLACEMENT OF PISTON AND DRIVING SET – Every 10,000 hours of run time, as indicated by the hourmeter, the piston set and driving set must be replaced. The pump must be returned to the factory for this replacement. Exchange rebuilt pumps are available. Contact factory.

  • REPLACE OF CRANKSHAFT BEARINGS – Every 20,000 hours of run time, as indicated by the hourmeter, the crankshaft bearings must be replaced. The pump must be returned to the factory for this replacement. Exchange rebuilt pumps are available. Contact factory.
