TROUBLESHOOTING GUIDE
Problem Encountered Possible Cause Possible Solution
The compressor does not
start or restart: Power cord not plugged in. Plug cord into grounded outlet.
Motor/Pressure switch in
OFF position Move switch to AUTO position.
Motor thermal overload switch has
tripped. Turn air compressor off, wait until the motor is cool, then
press motor thermal overload (red) button firmly until click
is heard.
Fuse blown or circuit breaker has
tripped. Replace fuse or reset circuit breaker.
Check for proper fuse amperage.
Check for low voltage conditions.
Disconnect any other electrical appliances from circuit or
operate air compressor on its own branch circuit.
Wrong gauge wire or length of
extension cord. Check chart in instruction manual for proper gauge wire
and cord length.
Air tank pressure exceeds motor/pressure
switch "cut-in" pressure. Motor will start automatically when air tank pressure drops
below "cut-in" pressure of motor/pressure switch.
Pressure release valve on
motor/pressure switch has not
unloaded pump head pressure. Bleed the line by moving the switch to the OFF position.
Defective motor, motor capacitor,
motor/pressure switch. Contact Consumer Helpline at 1-800-423-3598.
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.
Bearing, piston or connecting rod
failure. STOP THE COMPRESSOR! Contact Consumer Helpline at
1-800-423-3598.
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.
When in the Start/Stop
option, motor runs
continuously: Motor/Pressure switch does not shut
off motor when air compressor
reaches "cut-out" pressure and safety
relief valve activates. 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.
Air compressor is incorrectly sized. 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: Defective pilot valve, the check valve is
stuck open. Remove, clean or replace.
