Double Insulation; Extension Cords - Craftsman 315.281260 Operator's Manual

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.
_I_ WARNING: The double insulated system is
intended to protect the user from shock resulting
from a break in the toots internal insulation. Observe
all normal safety precautions to avoid electrical
shock.
NOTE: Servicing of a product with double insulation
requires extreme care and knowledge of the system and
should be performed only by a qualified service techni-
cian. For service, we suggest you return the product to
your nearest Sears or other qualified service center for
repair. Always use original factory replacement parts when
servicing.
ELECTRICAL CONNECTION
This product 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
product on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If
the product does not operate when plugged into an outlet,
double-check the power supply.
EXTENSION CORDS
When using a power toot 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 undersized cord will cause a drop in line voltage, re-
suKing in overheating and loss of power. Use the chart to
determine the minimum wire size required in an extension
cord. 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 "WA" on the cord's jacket.
Before using any 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
product with a damaged cord since touching the
damaged area could cause electrical shock resulting
in serious injury.
