Double Insulation; Extension Cords; Electrical - Craftsman 315.116920 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. A/I exposed metal parts are
isolated from the internal metal motor components with
protecting insulation. Oouble insulated tools do not need
to be grounded.
A WARNING: The double insulated is
system
intendedto protect the user hom shock resulting
from a break in the tool's In_ernalInsulation.Observe
all normal safety precautkmsto avo_ elactr(csl
shock.
NOTE: Servicingof a tool with double insulationrequires
extreme care and knowledge of the system and should
be performed onlyby a qualified servicetechnician. For
service, we suggestyou returnthe tool to your nearest
authodzed service center for repair.A/ways use odglnal
factory replacement parts when servicing.
ELECTRICAL CONNECTION
This tool has a precision-builtelectric motor, It shouldbe
connected to a power supply that is 120 volta, 60 Hz,
AC only (normal household current). Do not operate
this tool on direct current(DC). A substantialvoltagedrop
wilt cause a loss of power and the motorwill overheat. If
your tool does not operate when plugged into an outlet,
doubts-check the power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the tool will draw. An
undersized cord will cause a drop in line voltage, resulting
in overheating and toss of power. Usa the chart to deter-
mine the minimum wire size required in an extension cord.
Only round jacketed cords listed by Underwriters Labora-
tories (UL) should be used,
When working outdoors with a tool, use an extension
cord that Is designeq 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,
,_IL WARNING: Check extensioncords before each
use. If damaged reprecaimmediately.Never use tool
with a damaged cord since touchingthe damaged
area could cause electricalshock resuittngin sertous
injury.
