Note: Troubleshooting problems may have similar causes and solutions.
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 reg-
ulate pressure Dirty or damaged regulator inter-
nal 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.
