DOUBLE INSULATION
Double insulation is a concept in safety in electric products,
which eliminates the need for the usual three-wire grounded
power cord. All exposed metal parts are isolated from the
internal motor components. Double insulated products do
not need to be grounded.
WARNING:
The double insulated system is intended to protect the
user from shock resulting from a break in the product's
internal wiring. 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 the nearest authorized
service center for repair. Always use original factory replace-
ment parts when servicing.
ELECTRICAL CONNECTION
This is a hybrid product capable of alternating current (AC)
through an extension cord or direct current (DC) through a
cord or battery pack. If the product does not operate when
an extension cord or battery pack is installed, double check
the power supply.
To use alternating current, connect the product to a power
supply that is 120 volts, AC only (normal household
current) 60 Hz.
To use direct current, install a manufacturer's-recom-
mended 20V battery pack only.
NOTE: Do not operate this product on direct current through
an extension cord. Doing so would cause a loss of power
and could cause the product to overheat.
EXTENSION CORDS
When using a product 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 using this product outdoors, use an extension cord that
is designed for outside use. This type of cord is designated
with "WA" or "W" on the cord's jacket.
Before using any extension cord, inspect it for loose or ex-
posed wires and cut or worn insulation.

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 work-
ing with this product. Failure to do so can result in
serious personal injury.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use a product with a
damaged cord since touching the damaged areas could
cause electrical shock resulting in serious injury.
