Problem Encountered

Possible Cause

Possible Solution

When in the Start/Stop
option, motor runs continu-
ously:

Overheating:

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

Air continues to leak at
motor/pressure switch
release valve while motor
is running:

Air leaks from safety relief
valve:

Air leaks at pump:

Air leaks at fittings:

Air leaks in air tank:

Air blowing from inlet fil-
ter:

Motor/Pressure switch does not shut off
motor when air compressor reaches "cut-out"
pressure and safety relief valve activates.

Air compressor is incorrectly sized.

Poor ventilation.

Dirty cooling fins.

Defective pilot valve, the check valve is stuck
open.

Defective motor/pressure switch.

Check valve stuck in open position.

Possible defective safety relief valve.

Excessive tank pressure.

Blown gaskets.

Fittings are not tight enough.

Defective or rusted air tank.

Damaged inlet (reed) valve.

Move the motor/pressure switch to the "OFF" posi-
tion. 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 com-
pressor. Either use a smaller tool or a larger air com-
pressor.

Relocate the air compressor to an area with an
ample supply of cool, dry, and well-circulated air is
available.

Clean the outer surfaces of the cooling fins on the
pump and motor assembly.

Remove,  clean or replace.

Replace.

Replace check valve. DANGER - Do not disassemble
the check valve with tank pressurized. Open tank pet-
cock valve to allow air to escape from tank prior to
servicing.

Operate safety relief valve manually by pulling on
ring. If it still leaks, it should be replaced.

Defective motor/pressure switch. Replace.

Replace blown gaskets and torque head bolts to 20
ft./lbs. CAUTION - Replace head gasket with a new
one each time the head is removed to ensure proper
sealing.

Tighten fittings where air can be heard escaping.
Check fittings with soapy water solution. DO NOT
OVERTIGHTEN.

Air tank must be replaced. DO NOT ATTEMPT TO
REPAIR AIR TANK!
