ELECTRICAL INFORMATION
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, where two systems of insulation are pro-
vided. This 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 electric shock resulting
from a break in the tool’s internal insulation. Observe all normal safety precautions to avoid electrical
shock.
1. REPLACEMENT PARTS
When servicing use only identical replacement parts.
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 bringing the product to you near-
est authorized service center for repair. Always use original factory replacement parts when servicing.
2. POLARIZED PLUGS
To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This
plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
3. SERVICE AND REPAIR. To avoid danger, electrical appliances must only be repaired by qualified service tech-
nician using original replacement parts; otherwise this may result in considerable damage to the user.
WARNING:
To avoid electrocution, do not use in wet or damp areas or expose to rain.
GUIDELINES FOR USING EXTENSION CORDS
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.
