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.
