POSSIBLE CAUSE
Tank petcock is open
Prolonged excessive use of air
Compressor not large enough
Restricted check valve
Hole in air hose

Valve leaks
Fittings leak
Air leaks from regulator, Dirty or damaged regulator
or regulator does not internal parts.

SOLUTION
Close petcock
Decrease amount of air used.
Check air requirement of accessory. If it is higher than CFM and
)ressure supplied by compressor, you need a larger compressor.
Most accessories are rated at 25% of actual CFM while running
continuously.
Remove and clean or replace.
Check and replace if necessary.
_k LvAvg-'1=_l_ll_[=']mlmmediately replace tank. DO NOT attempt to repair.
Replace any faulty seals.
Replace worn parts and reassemble with new seals.
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.
Replace regulator or internal parts.
Contact authorized service center.
Motor will start automatically when tank pressure drops below
kick-in pressure of pressure tank.
Let motor cool off and overload switch will automatically reset. This
may take several minutes.
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.
Remove and clean or replace.
Check for proper gauge and extension cord length.
Check valve stuck open
Wrong wire gauge in extension
cord
Loose electrical connections Contact authorized service center,
Paint spray on internal motor Have checked at service center. Do not operate compressor in the
_arts paint spray area
Possible defective motor Have checked at service center.
