DOUBLE INSULATION
Double insulationis a concept in safety in electricpower
tools, which eliminates the need for the usualthres-wlre
grounded power cord. AJiexposed metal parts are
isolatedfrom the internalmetal motor componentswith
protectinginsulation.Double insulatedtools do not need
to be grounded.
WARNING: The double insulated system is
intended to pmteot the user from shook resulting
from a break in the tool's internalinsulation.Observe
ell norm_ safety presautio_s to evo{daIeotl'tce, I
shook.
NOTE: Servicingof a tool with double insulationrequires
extreme care and knowledge of the system and should
be performedonly by a qualified servicetechnician. For
service,we suggestyou return the tool to your nearest
authorrzed service center for repair.A_vaysuse original
faotory replacement parts when servicing.
ELECTRICAL CONNECTION
This tool has a precLsion-built slectYicmotor, 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 directcurrent (DC). A substantialvoltage drop
will cause a loss of power and the motor will overheat. If
yourtool does not operate when plugged into an outlet,
double-check the power suppry.
EXTENSION CORDS
When using a power tool at a considerabledistance from
a power soume, be sure to use an extensioncord that has
the capacity to handle the currentthe toot will draw. An
undersizedcordwill cause a drop in tinsvoltage, resulting
in overheatingand lose of power, Use the ohartto deter-
mine the minimumwire size required in an extensioncord.
Only roundjacketed cords listed by Undsrwriter'sLabora-
tories (UL) shouk_be used.
When working outdoorswith a tool, use an extension
cord that is designed for outside use. Thistype of cord is
designatedwith =WA= on the cord'siacket.
Before usingany extensioncord, inspect it for loose or
exposed wires and cut or worn insulation.

WARNING: Keep the extension cord clear of the
workingarea, Positionthe cord so that itwiU not get
caught on lumber,toolsor other obstructfonswhile
you are workingwith a power tool. Failureto do so
can result in serious personalinjury.
WARNING: Check extension cords before each
use. If damaged repface Immediately.Never use tool
with a damaged cord since touchingthe damaged
area could cause electricalshock resu{tingin serious
Injury.
