EXTENSION CORDS

Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept the
tool's plug. When using a power tool at a considerable
distance from the power source, use an extension cord
heavy enough to carry the current that the tool will draw. An
undersized extension cor d will cause a dro p 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
(UL) should be used.

**Ampere rating (on tool faceplate)

Cord Length

25'
50'

**Used on 14 gauge - 15 amp circuit,. Or 12 gauge – 20 amp circuit

NOTE: AWG = American Wire Gauge

When working with the tool outdoors, use an extension
cord that is design ed 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.

Keep the extension cord clear of the working area.
Position the cord so tha t it wil l not ge t caug ht on lum ber,
tools or other obstructions while you are working with a
power tool. Failure to do so can result in serious
personal injury.

WARNING:

WARNING:

Check extension cords before each use. If damaged
replace immediately. Never use tool with a damaged
cord since touching the damaged area could cause
electrical shock resulting in serious injury.

ELECTRICAL CONNECTION

This tool is powered b y a precision built electric motor. It
should be connected to a power supply that is 115 volts,
60 Hz, AC only (normal household current). Do not
operate this tool on direct current (DC). A substantial
voltage drop will caus e a loss of power and the moto r will
overheat. If the product does not operate when plugged
into an outlet, double check the power supply.

SPEED AND WIRING

The speed is not constant and decreases under a loa d or
with lower voltage . For voltage, the wiring in a shop is as
important as the motor ’s ho r s epo wer rat ing. A line i nte nded
only for lights cannot properly carry a power tool motor.
Wire that is heav y enough for a short distance wi ll 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.

In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the r isk of electric shock. This tool 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
