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
protecting insulation. Double insulated tools do not need
to be grounded.
Important:
Servicing of a tool with double insulation
requires extreme care and knowledge of the system and
should be performed only by a qualified service
technician. For service, we suggest you return the tool
to your nearest authorized service center for repair.
When servicing, use only identical Craftsman
replacement parts.
_lh, WARNING:
The double insulated system is
intended to protect the user from shock resulting
from a break in the tool's internal wiring. Observe
all normal safety precautions to avoid electrical
shock.
ELECTRICAL
CONNECTION
The rotary grinder has 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 your tool does not operate
when plugged into an outlet, double-check
the power
supply.
EXTENSION
CORDS
The use of any extension cord will cause some loss of
power. To keep the loss to a minimum and to prevent
tool overheating,
use an extension cord that is heavy
enough to carry the current the tool will draw.
A wire gage size (A.W.G.) of at least 16 is
recommended for an extension cord 100 feet or less in
length. When working outdoors, use an extension cord
that is suitable for outdoor use. This type of cord is
designated with "WA" on the cord's jacket.
_b,
CAUTION:
Keep extension cords clear of the
working area. While you are working with a power
tool, position the cord so that it will not get caught
on lumber, tools, or other obstructions.

WARNING:
Check extension cords before each
use. If damaged, replace them immediately. Never
use a damaged cord with this tool. Touching the
damaged area could cause serious injury due to
electrical shock.
Extension cords suitable for use with your tool are
available at your nearest Sears retail store.
