Problem Possible Cause Solution

The compressor does not run. Loss of power or overheating.

There is no electrical power being

supplied to compressor or, the power

switch is in the OFF position.

A fuse has blown at the power supply.

A breaker has tripped at the power

supply.

Thermal overload open.

The pressure switch is bad.

Tank is full of air.

Check for proper use of extension cord.

Check to be sure the compressor is plugged

in and the power switch is in the ON position

Replace the fuse at the power supply.

Reset the breaker at the power supply

and determine why the problem happened.

First unplugged the compressor and wait until

it becomes cool. Motor will restart when cool

Replace the pressure switch.

Compressor will turn on when tank

pressure drops to cut-in pressure.

The motor hums, but does not run

or runs slowly.

The voltage from the power supply is low.

The gauge wire or the length of

extension cord is wrong.

The motor winding is shorted or broken.

The unloader or check valve is defective.

Check the voltage with a voltmeter.

Use the correct wire gauge and length

extension cord.

Take the compressor to a service center.

The fuses blow or the circuit

breaker trips repeatedly.

The fuse size is incorrect or the circuit

is overloaded.

The gauge wire or the length of

extension cord is wrong.

The unloader or check valve is defective.

Check the fuse or breaker at the power supply is the correct

size and type. Be sure to use only time-delay fuses to avoid

overloading a curcuit, disconnect other electrical appliances

from circuit or operate compressor on its own branch circuit.

Use the correct wire gauge and length

extension cord.

Take the compressor to a service center.

The thermal overload protector cuts

out repeatedly.

The voltage from the power supply is low.

A poorly ventilated room is causing the

motor to overheat.

The gauge wire or the length of

extension cord is wrong.

Check the voltage with a voltmeter.

Move the compressor to well-ventilated

area.

Check for proper gauge wire and cord

length.

The air receiver pressure drops

when the compressor shuts off.

The connections are loose or leaking

(fittings, tubing, etc.).

The drain valve is loose.

The check valve is leaking.

Check all the connections with soapy water and look for

bubbles. Tighten any loose conections until the leak stops.

Tighten the drain valve.

Take the compressor to a service center.

There is excessive moisture in the

air discharge.

There is excessive water in the air tank.

The humidity is high.

Drain the tank to remove water.

Move the compressor to an area of less humidity or use

an air line filter to reduce moisture discharge in the tank.

Air is leaking from the compressor. The hose connection is loose or

improperly sealed.

The air hose is broken or damaged.

Ensure connections are sealed with

thread sealing tape and tightened.

Replace the air hose.

The compressor runs continuously The tank drain valve is open.

The pressure switch is defective.

The usage is excessive.

Ensure the tank drain valve is closed.

Take the compressor to a service center.

Decrease the amount of tool run-time; the compressor is

not large enough to supply the air requirement of the tool.

The compressor vibrates.

The compressor mounting bolts are loose.

Tighten mounting bolts.

The air output is lower than normal. The inlet valves are broken.

The connections are leaking.

Take the compressor to a service center.

Apply thread sealing tape to fitting and tighten.

WARNING:

Do not disassemble check valve while

air is in tank - empty the all the air out of

the tank before dissasembly.
