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.
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 pre-
cautions to avoid electrical shock.
Important: Servicing of a tool with double insulation requires
extreme care and knowledge of the system and should be
performed only by a qualified service technician. For ser-
vice, we suggest you return the tool to your nearest autho-
rized service center for repair. Always use original factory
replacement parts when servicing.
ELECTRICAL CONNECTION
The drill has a precision-built electric motor. It should be con-
nected to a power supply that is 120 volts, 60 Hz, AC only
(normal household current). Do not operate this tool on di-
rect current (DC). A substantial voltage drop will cause a loss
of power and the motor will overheat. If your tool does not
operate when plugged into an outlet, double-check the power
supply.
EXTENSION CORDS
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 tool will draw. An under-
sized cord will cause a drop in line voltage, resulting in over-
heating 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 tool, use an extension cord
that is designed for outside use. This type of cord is desig-
nated 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.

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 re-
sult in serious personal injury.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use tool with a damaged
cord since touching the damaged area could cause
electrical shock resulting in serious injury.
