The compressor motor stalls:

Overloaded motor.

Have a certified electrician check the motor and wiring.

 

 

Proceed with his or her recommendations.

 

Improper lubrication.

See LUBRICATION section in instruction manual.

 

Low oil level.

Check oil level and fill if necessary.

 

Defective check valve.

Replace check valve.

Excessively noisy operation:

Loose motor pulley or pump flywheel.

Tighten pulley and/or flywheel (where applicable).

 

Lack of oil in the pump crankcase.

Check oil level. If low, check for possible bearing damage.

 

 

Add correct amount of oil.

Carbon deposits on pistons or valves.

Remove cylinder head and inspect. Clean or replace parts as needed.

Worn connecting rod.

Replace with new connecting rod.

Worn piston wrist pin bushing.

Remove piston/connecting rod assembly from the compressor

 

and inspect for excess wear. Replace worn parts as needed.

Worn bearings.

Replace worn bearings as needed.

 

NOTE: Dirty oil can cause accelerated wear.

 

Change oil frequently using recommended oil.

 

 

Noisy check valve.

Replace check valve.

Air compressor is incorrectly sized.

Move the motor/pressure switch to the OFF position. If the motor does not shut off, unplug the air compressor. If the electrical contacts are welded together, replace the pressure switch.

Limit the air pressure to the capacity of the air compressor. Either use a smaller tool or a larger air compressor.

Overheating:

Poor ventilation

Relocate the air compressor to an area with an ample supply

 

 

of cool, dry, and well-circulated air is available.

 

Dirty cooling fins.

Clean the outer surfaces of the cooling fins on the pump and

 

 

motor assembly.

 

 

 

Air continues to leak at motor/pressure switch release valve after motor stops:
