TROUBLE SHOOTING GUIDE
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
Possible Correction
Air leaks at the check valve or
at the pressure relief valve.
A defective check valve results in a constant air leak at the
pressure release 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
cylinder.
Be sure of proper torque on head bolts. If leak remains, contact
a service technician.
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.
Pressure reading on the
regulated pressure gauge
drops when an accessory is
used.
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’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 your service
technician.
Excessive moisture in the
discharge air.
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.
Air leaks from the tank body or
tank welds.
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.
