EXTENSION CORDS

NOTE: Avoid use of extension cords.
1. For optimum performance, plug the compressor power cord
directly into a grounded wall socket. Do not use an extension
cord unless absolutely necessary. Instead, use a longer air
hose to reach the area where the air is needed.
2. If use of an extension cord cannot be avoided, the cord should
be no longer than 50 feet and be a minimum wire size of 12
gauge (AWG). Do not use a 16 or 14 gauge extension cord.
3. 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.
An undersized cord will cause a drop in line voltage, resulting
in loss of power and overheating. The smaller the gauge
number, the heavier the cord.
4. 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.
5. Before using an extension cord, inspect it for loose or exposed
wires and cut or worn insulation.
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 compres-
sor with a damaged cord since touching the damaged area
could cause electrical shock resulting in serious personal
injury.
NOTE: Use longer air hoses instead of long extension cords.
Your air compressor will run better and last longer.

ELECTRICAL CONNECTION

1. 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).
2. 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.

SPEED AND WIRING

1. The no-load speed of the electric motor varies by model and
specifi cation. 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.
2. 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

1. In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This air compressor is
equipped with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged

ELECTRICAL SAFETY

into a matching outlet that is properly installed and grounded
in accordance with all local codes and ordinances.
2. Do not modify the plug provided. If it will not fi t the outlet, have
the proper outlet installed by a qualifi ed electrician.
3. 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.
4. Check with a qualifi ed electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
5. Replace a damaged or worn cord immediately.
WARNING
grounding conductor can result in a risk of electric shock.
6. This air compressor is intended for use on a circuit that
has an outlet like the one shown in the fi gure 1. It also has
a grounding pin like the one shown. This product must be
grounded.
7. Never use an electrical adapter with this grounded plug.
