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
Allow the motor to cool down.
Motor windings are burned out.
Contact Customer Support.
The motor does not start and
makes a humming noise.
Capacitor is burned out.
Contact Customer Support
The motor does not start or starts
slowly.
Low voltage supply to the motor.
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.. Use heavy duty extension
cords.
Ensure that the air compressor is plugged into a
fully functional power outlet
Noisy with metallic clangs.
Motor/Pump head gasket or reed valve is
damaged
Stop the compressor and contact the part dealer.
The compressor does not reach
the maximum pressure.
Motor/Pump head gasket or reed valve is
faulty.
Stop the compressor and contact the part dealer.
The compressor doesn't seem to
provide as much air as it did
when new and/or the compressor
cuts off within a much shorter
time period.
The pressure switch needs adjusting.
Stop the compressor and contact the part dealer.
The tank is full of water due to
condensation.
Open the drain valve and release the water from
the tank.
The motor pump unit does not
stop when the tank pressure
reaches its maximum working
pressure.
Pressure switch defective or needs
adjusting.
Stop the compressor and replace part.
