The following schedule is geared toward a consumer whose compressor is used in a normal working environment 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. Air compressors used in an extremely dirty and/or hostile environment will require a greater frequency of all maintenance checks. Oil Changing For changing the pump oil, be sure to do the following: 1. Turn the unit off and unplug the power cord from the receptacle. 2. Allow the compressor time to cool if it has been in operation. 3. Open the drain valve to bleed all air from the tank. 4. Close the drain valve. 5. Remove the oil fill cap on the pump. 6. Remove the sight glass with a box end wrench or socket. Drain the oil into a suitable container and dispose of properly. The compressor may need to be tipped slightly towards the drain hole to allow all of the oil to drain. The air compressor should be turned off and unplugged from the power source before any maintenance is performed as well as the air bled from the tank and the unit allowed time to cool. Personal injuries could occur from moving parts, electrical sources, compressed air or hot surfaces. 7. Reattach the sight glass. Note: Torque the sight glass 10-12 inch Ibs. when re-assembling. Be sure the gasket is between the sight glass and the pump crankcase. 8. Refill the compressor pump with an air compressor oil such as SAE-30 non-detergent (API CG/CD Heavy Duty) oil at slow intervals until the oil reaches the center of the red circle in the sight glass. Use a SAE-10 during extreme winter conditions. Storage For storing the air compressor, be sure to do the following: 1. Turn the unit off and unplug the power cord from the 4.

PROBLEM POSSIBLE CORRECTION Air leaks at the check valve A defective check valve results in a constant air leak at the pressure release valve or at the pressure relief valve, i when there is pressure in the tank and the compressor is shut off. Drain the tank, then remove and clean or replace the check valve. Air leaks between head and Be sure of proper torque on head bolts. If leak remains, contact a service cylinder, technician.

Be sure the compressor's air output is greater than your tool's air consumption rate. Air leaks from the tank body Never drill into, weld or otherwise modify the air tank or it will weaken. The tank can or tank welds. rupture or explode. Compressor cannot be repaired. Discontinue use of the air compressor.
