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 pres-
sure 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.
Excessive tank pressure.
Motor will not start.
Thermal overload protector cuts
out repeatedly.
Excessive moisture in the discharge air.
Air leaks from the tank body or tank welds.
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 con-
tinues 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.
Adjust the regulated pressure under flow conditions (while accessory is
being used). It is normal for the gauge to show minimal pressure loss dur-
ing initial use of the tool.
Move the Auto-On/Off switch to the Off position. If the unit doesn't shut
off, unplug it from the power source and contact a service technician.
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.
1. Lack of ventilation, room temperature too high. Move to cooler
environment.
2. Excessive air usage, compressor too small for this application. Lower
rate of consumption.
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.
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.
