DOUBLE INSULATION
Double insulation is a concept in safety in electric power
tools, which eliminates the need for the usual three-wire
grounded power cord. All exposed metal parts are isolated
from the internal metal motor components with protect-
ing insulation. Double insulated tools do not need to be
grounded.
WARNING:
The double insulated system is intended to protect the
user from shock resulting from a break in the tool’s in-
ternalinsulation.Observeallnormalsafetyprecautions

ELECTRICAL CONNECTION
This product has a precision-built electric motor. It should be
connected to a power supply that is nominal 120V/60Hz
AC (typical U.S. household circuit). Except with battery

not operate when plugged into an outlet, double-check the
power supply.
GFCI

product. Receptacles are available having built-in GFCI
protection and may be used for this measure of safety.
EXTENSION CORDS
When using a power product at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the product will draw. An

theminimumwiresizerequiredinanextensioncord.Only
round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
When working outdoors with a product, use an extension
cord that is designed for outside use. This type of cord is
designated with “W-A” or “W” on the cord’s jacket such
as an extension cord of cord type SW-A, SOW-A, STW-A,
STOW-A, SJW-A, SJOW-A, SJTW-A. or SJTOW-A.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
Make sure the cord and extension cord are securely
attached as shown in fig. 5, then connect the plug end of
the power cord into the receptacle end of the extension
cord. Check that connection is secure.

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
replaceimmediately.Neveruseproductwithadamaged
cord since touching the damaged area could cause
electrical shock resulting in serious injury.
