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 pro-
tect 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 replacement
parts when servicing.
ELECTRICAL CONNECTION
This product has a precision-built electric motor.
It should be connected to a power supply that is
nominal 120V/60Hz AC (typical U.S. household
circuit). 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 5.
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 "W-A" or "W"
on the cord's jacket.
ELECTRICAL
FEATURES
Before using any extension cord, inspect it for
loose or exposed wires and cut or worn insulation.
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 5, 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.

NOTE: AWG = American Wire Gauge
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 obstruc-
tions 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.
