Troubleshooting Guide

The air compressor should be turned off and unplugged from the power source before any maintenance is performed as well as the air bled from the tank and the unit allowed time to cool.

Personal injuries could occur from moving parts, electrical sources, compressed air, or hot surfaces.

PROBLEM

Air leaks at the check valve

or at the pressure relief valve,

Air leaks between head and

cylinder.

Air leak from safety valve.

Pressure reading on the regulated pressure gauge drops when an accessory is used.

POSSIBLE CORRECTION

A defective check valve results in a constant air leak at the pressure relief valve when there is pressure in the tank and the compressor is shut off. Drain the tank, then remove and clean or replace the check valve.

Be sure of proper torque on head bolts. If leak remains, contact a service technician.

Operate the safety valve manually by pulling on the ring. If the valve continues to leak when in the closed position,it should be replaced.

If there is an excessive amount of pressure drop when the accessory is used, replace the regulator.

NOTE:

Adjust the regulated pressure under flow conditions(while accessory is being used), It is normal for the gauge to show minimal pressure loss during initial use of the tool.

Excessive tank pressure.

Move the Auto-On/Off lever to the Off position. If the unit doesn'tshut off, unplug it

 

from the power source and contact a service technician.

 

Motor will not start.

Make sure power cord is plugged

in and the switch is on. Inspect for the

proper size

 

fuse in your circuit box.

If the

fuse was tripped,

reset it and restart

the unit. If

 

repeated tripping occurs,

replace the check valve

or contact a service technician.

Excessive moisture in the discharge air.

Air leaks from the tank body or tank welds.

Remove the water in the tank by draining after each use. High humidity environments will cause excessive condensation. Utilize water filters on your air line.

NOTE:

Water condensation is not caused by compressor malfunction. Be sure the compressor's air output is greater than your tool's air consumption rate.

Never drill into, weld or otherwise modify the air tank or it will weaken. The tank can rupture or explode. Compressor cannot be repaired. Discontinue use of the air compressor.
