DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, which eliminates the need for the
usual threewire 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 center 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 volts, 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.
ELECTRICAL INFORMATION
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.
