TROUBLESHOOTING CHART
PROBLEM
POSSIBLE CAUSE
SOLUTION
Low pressure or not
enough air
or
Compressor does not
stop
Tank drain valve is open
Close drain valve
Fittings Leak
Check fittings with soapy water. Tighten or reseal leaking fittings. DO
NOT OVERTIGHTEN.
Restricted air intake
Clean or replace air filter element.
Prolonged excessive use of air
Decrease amount of air used.
Compressor not large enough
Check air requirement of accessory. If it is higher than CFM and
pressure supplied by compressor, you need a larger compressor.
Most accessories are rated at 25% of actual CFM while running
continuously.
Restricted check valve
Remove and clean or replace.
Hole in air hose
Check and replace if necessary.
Tank leaks
Immediately replace tank. DO NOT attempt to repair.
Valve leaks
Replace worn parts and reassemble.
Excessive starting and
stopping, while not in
use
Fittings leak
Check fittings with soapy water. Tighten or reseal leaking fittings. DO
NOT OVERTIGHTEN.
Replace worn parts and reassemble with new seals.
Air leaks from regulator,
or regulator does not
regulate pressure
Dirty or damaged regulator internal
parts.
Replace regulator or internal parts.
Regulated pressure
gauge reading drops
when air accessory is
being used
This is normal
If pressure drops too low, adjust regulator while accessory is used.
Compressor not large enough
Check air requirement of accessory. If it is higher than CFM and
pressure supplied by compressor, you need a larger compressor. Most
accessories are rated at 25% of actual CFM while running continuously.
Circuit breaker trips
(fuse blows) too often
Low voltage
Furnish adequate power. If using extension cord, try without.
Excessive wire length
Consult electrician.
Restricted air passages
Contact authorized service center.
Back pressure in pump head
Replace check valve, pressure switch, bleeder valve.
Overheating
Poor ventilation
Relocate compressor to an area with cool, dry and well-circulated air.
Dirty cooling surfaces
Clean all cooling surfaces of pump and motor thoroughly.
Leaking valve
Replace worn parts and reassemble with new seals.
Motor stalls
Low voltage
Furnish adequate power.
Defective pressure switch bleeder valve Replace pressure switch bleeder valve.
Pressure relief valve
opens
Tank pressure exceeded normal
operating pressure
Replace pressure switch
Pressure switch stuck
Replace pressure switch
Motor will not run
Tank pressure exceeds preset pressure
switch limit
Motor will start automatically when tank pressure drops below
kick-in pressure of pressure tank.
Motor overload protection has tripped
To reset the motor overload, toggle the ON/OFF switch to the “OFF’
position and unplug the unit from the power outlet. Allow a minimum of
10 minutes for motor overload cut-out to cool and reset. Unit can then
be plugged in and restarted.
Circuit breaker tripped
• Reset circuit breaker. Do not use circuit breaker with higher rating
than specified for your branch circuit.
• Check for low voltage and proper extension cord size.
• Disconnect other applications from circuit. Operate compressor
on a dedicated circuit.
Check valve stuck open
Remove and clean or replace.
Pressure bleeder valve on pressure
switch has not unloaded head pressure
Bleed line by moving pressure switch lever to OFF Position before
restarting. If bleeder valve does not open, replace bleeder valve.
Wrong wire gauge in cord or excessive
extension cord length
Check for proper gauge and extension cord length.
Loose electrical connections
Contact authorized service center.
Paint spray on internal motor parts
Have checked at service center. Do not operate compressor in the
paint spray area
Possible defective motor
Have checked at service center.
