ELECTRICAL INFORMATION
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, where two systems of insulation are
provided. 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 insu-
lated tools do not need to be grounded, nor should a means for grounding be added to the product.
IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and
should be done only by a qualified service personnel using identical replacement parts. Always use original factory
replacement parts when servicing.
1. 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 a proper outlet. DO NOT modify the
machine plug or the extension cord in any way.
2. GROUND FAULT CIRCUIT INTERRUPTER PROTECTION (GFCI) should be provided on the circuit or
outlet used for this power tool to reduce the risk of electric shock.
3. SERVICE AND REPAIR. To avoid danger, electrical appliances must only be repaired by qualified service
technician using original replacement parts.
WARNING: To avoid electrocution, DO NOT use in wet or damp areas or expose to rain.
1. Examine extension cord before use. 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.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on
plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge 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. Run-
ning at a lower voltage will damage the motor.
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.
