ELECTRICAL INFORMATION

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 protect-
ing 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 bring the product to you
nearest authorized service center for repair. Always use original factory replacement parts when servicing.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed by a
licensed electrician.
WARNING: To avoid electrocution, do not use in wet or damp areas or expose to rain.
GUIDELINES FOR USING EXTENSION CORDS
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 a drop in line voltage resulting
in loss of power and overheating. The table below shows the correct size to be used according to cord length and
nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.
Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord
or have it repaired by a qualified person before using it. Protect your extension cords from sharp objects, excessive
heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected
with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in the OFF
position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a
lower voltage will damage the motor.
