PROBLEM

Air leaks at the check valve

or at the pressure relief vaive,

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.

Air leaks between head and Be sure of proper torque on head bolts, if leak remains, contact a service technician.

cylinder.

Air leak from safety valve. 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.

Pressure reading on the

regulated pressure gauge

drops when an accessory is

used. 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. It the unit doesn't shut 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'e air consumption rate.

Never ddfl 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
