DOUBLE INSULATION

Double insulation is a concept in safety in electric power tools, that 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.
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 centre for repair. Always
demand that original factory replacement parts be used when servicing.

ELECTRICAL CONNECTION

This product has a precision-built electric motor. It should be connected to a power
supply that is 120 V, AC only (normal household current), 60 Hz. 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 your 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.

GUIDELINES FOR USING EXTENSION CORDS

USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good
condition. When using an extension cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord will cause overheating. The table below
shows the correct size to use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
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.
