i n s t a l l a t i o n & g r o u n d i n g
Installation and Location
The compressor must be used on a stable level surface. The air compres-
sor must be used in a clean and well-ventilated area. The compressor
requires an unobstructed airflow and must be located a minimum of 18
inches from any walls or other obstructions.
Grounding Instructions
This product should be grounded. In the event of an electrical short cir-
cuit, 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. The plug must be
plugged into an outlet that is properly installed and grounded in accor-
dance with all local codes and ordinances.
This product is for use on a nominal 120-volt circuit and has a three-
prong grounding plug that looks like the plug illustrated in Figure 2. Make
sure that the product is connected to an outlet having the same
configuration as the plug. No adapter could be used with this product.
The use of a GFCI outlet is strongly recommended. The third prong is
to be used ground the tool and provide protection against electrical
shock. Never remove the third prong.
Check with a qualified electrician or serviceman if the grounding instruc-
tions 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.
DANGER
ELECTRIC SHOCK: Improper installation of the
grounding plug can result in a risk of electric shock. If
repair or replacement of the cord 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.

Extension Cords
We do not recommend the use on an extension cord with this product as
this may result in the loss of power and overheating of the motor. An
additional air hose should be used instead of an extension cord. However,
if the use of an extension cord is unavoidable, use only UL listed wire
extension cords that have three-pronged grounding type plugs and three
prong receptacles that accept the tool’s plug. Improper use of extension
cords may cause inefficient operation of you tool, which can result an
overheating.
Be sure your extension cord is rated to allow sufficient flow to motor.
Refer to the guide for minimum gauge required for extension cords.
Use of an extension cord heavy enough to carry the current the tool will
draw is very important. Especially when the power source is of great
distance. An extension cord that is insufficient will cause a drop in line
voltage, resulting in power loss and causing the motor to overheat.
Guard against electrical shock. Avoid body contact with grounded ser-
vices such as pipes, radiators, ovens, stoves, and refrigerator enclosures.
If not properly grounded, this power tool can incur the potential hazard of
light trickle shock, particularly when used in damp locations. If an electri-
cal shock occurs, there is the potential of a secondary hazard such as
your hands contacting an operating air tool.
