Risk of Unsafe Operation. Unit cycles automatically when
power is on. When servicing, you may be exposed to voltage sources, com-
pressed air, or moving parts. Before servicing unit unplug or disconnect elec-
trical supply to the air compressor, bleed tank of pressure, and allow the air
compressor to cool.
Problem
Possible Cause
The compressor
does not run.
The motor hums
while running
slowly, or it does
not run at all.
The fuses blow
or circuit breaker
trips repeatedly.
TROUBLESHOOTING
□
There is a loss of power or
the motor is overheated.
□
There is no power to the
unit.
□
The circuit breaker has
tripped or a fuse has blown
at the main power source.
□
The thermal overload
protector is actuated.
□
The pressure switch is bad.
□
The compressor has reached
automatic shutoff pressure.
□
There is low voltage from
the power source.
□
The wrong gauge wire or
length of extension cord is
being used.
□
There is a shorted or open
motor wiring.
□
There is a defective check
valve or unloader.
