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.
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 original factory replace -
ment parts when servicing.
This product has a precision-built electric motor. It should
be connected to a power supply that is 120 volts, AC only
(normal household current), 60
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.
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 ex -
posed wires and cut or worn insulation.
A proper extension cord is available at an authorized service
Hz. Do not operate this

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.

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.
Check extension cords before each
use. If damaged replace immediately. Never use the
product with a damaged cord since touching the
damaged area could cause electrical shock resulting
in serious injury.
