ELECTRICAL
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 protect
-
ing 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 wiring. 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 technician. For service,
we suggest you return the tool to your nearest authorized
service center for repair. Always use original factory replace
-
ment parts when servicing.
ELECTRICAL CONNECTION
This tool has a precision-built electric motor. It should be
connected to a
power supply that is 120 V, AC only (nor-
mal household current), 60 Hz
. 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 the 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 product will draw. An
undersized cord will cause a drop in line voltage, resulting 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” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

**Used on 12 gauge - 20 amp circuit.
NOTE:
AWG = American Wire Gauge
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on lum
-
ber, 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 tool with a damaged
cord since touching the damaged area could cause
electrical shock resulting in serious injury.
