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.
W A R N I N G
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 return the product
to your nearest authorized service center for repair. Always use identical factory replacement parts when
servicing.

ELECTRICAL CONNECTION

This product 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 product does not operate when plugged into an outlet, double-check the power supply.
EXTENSION CORDS (See Figure 1)
When using a power tool at a considerable distance from a power source, be sure to use an
extension cord that has the capacity to handle the current the product will draw. An undersized
cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to
determine the minimum wire size required in an extension cord. Only round jacketed cords listed
by Underwriter's Laboratories (UL) should be used.
When working outdoors with a product, use an extension cord that is designed for outside use.
This type of cord is designated with "WA" on the cord's jacket.
Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.
It is possible to tie the extension cord and power cord in a knot to prevent them from becoming
disconnected during use. Make the knot as shown in figure 1, then connect the plug end of the
power cord into the receptacle end of the extension cord. This method can also be used to tie
two extension cords together.
