TROUBLESHOOTING
Problem Possible Cause Possible Solution
Circuit breaker/fuse trip often. 1. Excessive wire length causes
voltage to drop too much.
2. Restricted air passages.
3. Back pressure in pump head.
1. Do not use an extension cord.
Link additional air hoses together
to acquire additional length.
2. Check all air passages for clogs.
3. Have a qualified service technician
replace check valve and/or
pressure switch bleeder valve.
Overheating. 1. Poor ventilation.
2. Dirty cooling surfaces.
3. Leaking valve.

2. Defective pressure switch
bleeder valve.
1. Do not use an extension cord.
Link additional air hoses together
to acquire additional length.
2. Have a qualified service technician
replace defective pressure switch
bleeder valve.
Pressure relief valve opens. 1. Air tank pressure has exceeded
normal operating pressure.
2. Pressure switch is stuck.
1. Have a qualified service technician
replace pressure switch.
2. Have a qualified service technician
replace pressure switch.
Motor will not run. 1. Air tank pressure exceeds preset
pressure switch limit.
2. Motor overload protection has been
Tripped.
3. Air compressor attached to an
extension cord.
1. Motor will automatically start when
air tank pressure drops below 85
PSI pressure of air tank.
2. Replace blown fuse or reset circuit
breaker. Do not use a fuse or
circuit breaker with higher rating
than specific for your circuit
branch. Check for proper fuse;
15 AMP Buss fuse is acceptable.
Do not use an extension cord.
Link additional air hoses together
to acquire additional length.
Disconnect other applications from
circuit.
Operate air compressor on a dedi-
cated circuit.
Bleed line by moving pressure
switch lever to OFF position before
