Grounding Instructions
This product must be grounded. In the event
of an electrical short circuit, grounding
reduces the risk of electric shock by providing
an escape wire for the electric current. This
product is equipped with a cord having a
grounding wire with an appropriate grounding
plug. (See figure below.) The plug must be
plugged into an outlet that is properly installed
and grounded in accordance with all local
codes and ordinances. Check with a qualified
electrician or service personnel if these
instructions are not completely understood or
if in doubt as to whether the tool is properly
grounded.
Make sure that the product is connected to an
outlet having the same configuration as the
plug. No adapter should be used with this
product. If the product must be reconnected
for use on a different type of electric circuit,
qualified service personnel should make the
reconnection.
Extension Cords
Use only a 3-wire extension cord that has a
3-blade grounding plug, and a 3-slot
receptacle that will accept the plug on the
product. Make sure your extension
cord is in good condition. When using an
extension cord, be sure to use one heavy
enough to carry the current your product will
draw. Cords must not exceed 25 feet and #
12 AWG must be used.An undersized cord
will cause a drop in line voltage resulting in
loss of power and overheating.
Break-In Procedures
No break-in procedure is required by the
user. This product is factory tested to
ensure proper operation and performance.
WARNING!
Improper installation of the grounding plug will
result in a risk of electric shock. If repair or
replacement of the cord or plug is necessary, do
not connect the grounding wire to either flat
blade terminal. The wire with insulation having
an outer surface that is green with or without
yellow stripes is the grounding wire. Check
with a qualified electrician or serviceman if the
grounding instructions are not completely
understood, or if in doubt as to whether the
product is properly grounded. Do not modify the
plug provided; if it will not fit the outlet, have the
proper outlet installed by a qualified electrician.
This product is for use on a circuit having a
nominal rating of 120 Volts and is factory-
equipped with a specific electric cord and plug
to permit connection to a proper electric circuit.

Troubleshooting Guide
WARNING!
The air compressor should be turned off and unplugged from the power source before any mainte-
nance 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 pres-
sure relief valve.
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 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 con- tinues 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 pres-
sure. 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 a 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. Dis-
continue use of the air compressor.
