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.

100' 16 16
**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
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.
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 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, 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 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
14
power tool may not be able to support two or three tools.

GROUNDING INSTRUCTIONS
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 tool is equipped with
an electric cord having an equipment-groundIng conduc-
tor 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.
Improper connection of the equipment-grounding con-
ductor can result in a risk of electric shock. The conductor
with insulation having an outer surface that is green with
or without yellow stripes is the equipment-grounding con-
ductor. 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 tool is intended for use on a circuit that has an outlet
like the one shown in figure 1. It also has a grounding pin
like the one shown.
