ELECTRICAL INFORMATION
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.
NOTICE
：
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. Take the unit to a qualified
service dealer for inspection and possible repair using only identical replacement parts.
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.
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.
