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.
GROUND FAULT CIRCUIT INTERRUPTER
See Figure 1, page 15.
This unit is equipped with a Ground Fault Circuit Interrupter
(GFCI), which guards against the hazards of ground fault
currents. An example of ground fault current is the current
that would flow through a person who is using an appliance
with faulty insulation and, at the same time, is in contact
with an electrical ground such as a plumbing fixture, wet
floor, or earth.
GFCI receptacles do not protect against short circuits,
overloads, or shocks.
NOTE: To ensure readiness for use, press the reset button
each time you connect the tool to the power supply.
The GFCI receptacles can be tested with the TEST and
RESET buttons.
To test:

Depress the TEST button. This should cause the RESET
button to pop out.
 To restore power, depress the RESET button.
Perform this test monthly to ensure proper operation of the
GFCI.
ELECTRICAL
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 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 near-
est authorized service center for repair. Always use original
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
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” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
