TROUBLESHOOTING CHART
PROBLEM
POSSIBLE CAUSE
SOLUTION
Low pressure or not
enough air
or
Compressor does not
stop
Tank petcock is open
Close petcock
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.
Blown seals
Replace any faulty seals.
Valve leaks
Replace worn parts and reassemble with new seals.
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.
Replace any faulty seals.
Air leaks from regulator,
or regulator does not
regulate pressure
Dirty or damaged regulator
internal parts.
Replace regulator or internal parts.
Regulated pressure
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.
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.
Pressure relief valve
opens
Tank pressure exceeded normal
operating pressure
Contact authorized service center.
Control board failure
Contact authorized service center.
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
Let motor cool off and overload switch will automatically reset. This
may take several minutes.
Fuse blown or circuit breaker
tripped
• Replace blown fuse or reset circuit breaker. Do not use fuse or
circuit breaker with higher rating than specified for your branch
circuit.
• Check for proper fuse; “Fusetron” type T is acceptable.
• 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.
Wrong wire gauge in extension
cord
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.
