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.
_
WARNING:
The double insulated system is
intended to protect the user from shock resulting
from a break in the tool's internal insulation. Observe
all normal safety precautions to avoid electrical
shock.
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 sug-
gest you return the tool to your nearest authorized service
center for repair. Always use original factory replacement
parts when servicing.
ELECTRICAL
CONNECTION
This tool has a precision-built
electric motor. It should be
connected to a power supply that is 120 volts, 60 Hz, AO
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
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 loss of power. Use the chart to deter-
mine the minimum wire size required in an extension cord.
Only round jacketed cords listed by Underwriter's
Labora-
tories (UL) should be used.
When working outdoors with a tool, 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
become entangled in the rotating foam pad or
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.
A
WARNING:
Check extension cords before each
use. If damaged replace immediately. Never use
tool with a damaged cord since touching the dam-
aged area could cause electrical shock resulting in
serious injury.
