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 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 (UL) should be used.

When working with the tool 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.

A 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.

A 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 by a precision built electric motor.

It should be connected to a power supply that is 120

volts, AC only (normal household current), 60 Hz. 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 saw does not operate when plugged into
an outlet, double check the power supply.

SPEED AND WIRING

The no-load speed of this tool is approximately 5,000 rpm.
This 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 intend­

ed 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 a malfunc­
tion or breakdown, grounding provides a path of least

resistance for electric current to reduce the risk 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 ordinances.

Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.

iA WARNING:

Improper installation of the ground­

ing plug can result in a risk of electric shock. When
repair or replacement of the cord is required, 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 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 volt circuit and

has a grounding plug similar to the plug illustrated in fig­
ure 1. Only connect the product to an outlet having the
same configuration as the plug. Do not use an adapter

with this product.
