TROUBLESHOOTING
PROBLEM
POSSIBLE CAUSE
POSSIBLE SOLUTIONS
Pressure drop in the tank.
Air leaks at connections.
Let the compressor build pressure in
the tank, to the maximum pressure
if possible. brush soapy water on air
connections and look carefully for air
bubbles. Tighten leaky connections. If
the problem persists, contact the seller
for further advice.
The unloader valve leaks when
the compressor is idle.
unloader valve seal is defective.
Let the air in the air tank flow out until
all the pressure is released. Then remove
the unloader valve plug and clean the
valve seal. If necessary, replace the seal
and then reinstall all components.
The compressor stopped and does
not start.
The thermal protector turned on
because the motor is overheating.
Check that the main voltage corresponds
to the air compressor specifications. An
extension cord that is too thin or too
long can cause a voltage drop and cause
the motor to overheat.
Excessive use (over 1 hour continuous
use) can cause the motor to overheat
Allow the motor to cool down.
Motor windings are burned out.
