DOUBLEINSULATION
Doubleinsulation is a conceptin safetyin electricpower
tools, which eliminatesthe need for the usualthree-
wiregrounded powercord.All exposedmetalpartsare
isolatedfromthe internal m etalmotorcomponents with
protecting insulation. Doubleinsulated tools do not need
to begrounded.

ELECTRICALCONNECTION
Thisproducthasa precision-built electricmotor. I t should
beconnected to a power supply thatis 120volts,
AC only
(normal
household
current},
60 Hz. 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, page L
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
center.
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.

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: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.
