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.
NOTE: 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 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 nominal 120V/60Hz
AC (typical U.S. household circuit). 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.
GFCI
Ground Fault Circuit Interrupter (GFCI) protection should
be provided on the circuit(s) or outlet(s) to be used for the
snow shovel. Receptacles are available having built-in GFCI
protection and may be used for this measure of safety.
ELECTRICAL
EXTENSION CORDS
See Figure 1.
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 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 tool, use an extension cord
that is designed for outside use. This type of cord is desig-
nated 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.
It is possible to tie the extension cord and power cord in a
knot to prevent them from becoming disconnected during
use. Make the knot as shown in figure 1, then connect the
plug end of the power cord into the receptacle end of the
extension cord. This method can also be used to tie two
extension cords together.

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 lumber,
tools, or other obstructions while you are working with
a power tool. Failure to do so can result in serious per-
sonal 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.
