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 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 product to your near-
est authorized service center for repair. Always use original
factory replacement parts when servicing.

ELECTRICAL CONNECTION
This product 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
product on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If
the product 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
product. Receptacles are available having built-in GFCI
protection and may be used for this measure of safety.
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.
