SPEED AND WIRING
The no-load speed of the electric motor varies by model and
specification. The motor speed is not constant and decreases
under a load or with lower voltage. For voltage, the wiring
in a shop is as important as the motor’s horsepower rating.
A line intended only for lights cannot properly carry a power
tool motor. Wire that is heavy enough for a short distance will
be too light for a greater distance. A line that can support one
power tool may not be able to support two or three tools.
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
air compressor is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The
plug must be plugged into a matching outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
The conductor with insulation having an outer surface that
is green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
This product is for use on a nominal 120-V circuit and has
a grounding plug similar to the plug illustrated in Figure 1.
Only connect the product to an outlet having the same con-
figuration as the plug. Do not use an adapter with this product.
Never use an electrical adapter with this grounded plug.
WARNING:
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept the
air compressor’s plug. When using the air compressor at
a considerable distance from the power source, use an
extension cord heavy enough to carry the current that the
compressor will draw. An undersized extension cord will
cause a drop in line voltage, resulting in a loss of power
and causing the motor to overheat. Use the chart provided
below to determine the minimum wire size required in
an extension cord. Only round jacketed cords listed by
Underwriter’s Laboratories (ULC) should be used.

** Used on 12 gauge - 20 amp circuit.
NOTE:
AWG = American Wire Gauge
When working with the air compressor outdoors, use an
extension cord that is designed for outside use. This is
indicated by the letters “WA” on the cord’s jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
NOTE:
Use longer air hoses instead of long extension
cords. Your air compressor will run better and last longer.
ELECTRICAL CONNECTION
This air compressor is powered by a precision built electric
motor. It should be connected to a
power supply that is
120 volts, 60 Hz, AC only (normal household current)
.
Do not operate this tool on direct current (DC). A substantial
voltage drop will cause a loss of power and the motor will
overheat. If the air compressor does not operate when
plugged into an outlet, double check the power supply.
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on lumber,
tools, or other obstructions while you are working with a
power tool. Failure to do so can result in serious personal
injury.
WARNING:
Check the extension cords before each use. If damaged,
replace immediately. Never use the air compressor with
a damaged cord since touching the damaged area could
cause electrical shock resulting in serious personal injury.
