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.

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

The compressor is noisy with

metallic clangs.

Compressor head gasket or reed valve is

damaged

Stop the compressor and contact the dealer.

The compressor does not reach

the maximum pressure.

Compressor head gasket or reed valve is

faulty.

Stop the compressor and contact the 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 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 (75 PSI).

Pressure switch defective or needs

adjusting.

Stop the compressor immediately and contact

Customer Support.
