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 protecting insulation. Double-insulated tools do not need to be grounded.
To reduce the risk of electric shock, double-insulated
tools are equipped with a polarized plug (one blade is
wider than the other). This plug will fit into a polarized
outlet only one way. If the plug does not fit, contact a
qualified electrician to install a polarized outlet. Do not change
the plug in any way.

POWER REQUIREMENTS

This tool has a precision-built electric motor. It should be connected to a power supply that is 120 volts,
60 Hz, AC only (normal household current). 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 the tool does not operate when
plugged into an outlet, double check the power supply.
GUIDELINES FOR EXTENSION CORDS
Use a proper extension cord. Make sure extension cords are in good condition. When using an extension
cord, be sure to use a cord that is heavy enough to carry the drawn current needed by the saw. An
undersized cord will cause a drop in line voltage, resulting in loss of power an overheating.
WARNING!
The double-insulated system is intended to protect the user from shock resulting from
a break in the tool's internal wiring. Observe all normal safety precautions to avoid
electric shock.
WARNING!
Double insulation does not take the place of normal safety precautions when operating
this tool.
CAUTION!
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 centre
for repair. Always use original factory replacement parts when servicing. Do not
use power tools in wet or damp locations or expose them to rain or snow.
The table below shows the correct size to use, depending on the cord length and nameplate amperage rating.
If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Be sure extension cords are properly wired and in good condition. Always replace a damaged extension cord
or have it repaired by a qualified technician before using it. Protect extension cords from sharp objects,
excessive heat, and damp or wet areas.
Use a separate electrical circuit for power tools. This circuit must not be less than #14 wire with a 15 Amp
time-delayed fuse, and should be protected with a time-delayed fuse. Before connecting the tool 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's nameplate. Running at a lower voltage will damage the motor.
Danger! Keep hands away from blade.
WARNING!
Do not permit fingers to touch the terminal or the plug when installing or removing
the plug from an outlet.
WARNING!
To avoid electrical hazards, fire hazards, or damage to the tool, use proper circuit
protection.
WARNING!
Keep the extension cord clear of the working area. Position the cord so that it will not
get caught on lumber, tools, or other obstructions while you are working with a power
tool. Failure to do so can result in serious personal injury.
WARNING!
Do not permit fingers to touch the terminal or the plug when installing or removing
the plug from an outlet.
