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.

**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 "W-A" or "W" 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 V, 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 lo-
cal 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.
,_1I_ WARNING: Improper installation of the ground-
ing plug is able to 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.
