EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong ground-
ing 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.
WARNING:
Keep the extension cord clear of the working area. Po-
sition 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 product with a damaged
cord since touching the damaged area could cause
electrical shock resulting in serious injury.
ELECTRICAL CONNECTION
This product 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 product 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 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
This product must be grounded. 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
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.
WARNING:
Improper installation of the grounding 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 hav-
ing 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.
