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.
The unloader valve leaks when
the compressor is idle.
Unloader valve spring compressed.
Let the air in the tank flow out until all the pressure
is released. Then remove the unloader valve plug
and clean the valve spring and elongate. If
necessary, replace the spring and then reinstall all
components.
The compressor stopped and
does not start.
Overload cutout operated because of
motor overheating.
Check that the main voltage corresponds to
specifications. An extension cord that is too thin or
too long can cause a voltage drop and cause the
motor to overheat. Allow the motor to cool down.
Press the Reset Button to restart the air
compressor Ensure that the compressor is plugged
into a socket as close as possible to the consumer
unit or fuse box.
Motor windings are burned out.
