DOUBLE INSULATION
Double insulation is a concept in safety in electric
power tools, which eliminates the need for the usual
threewire 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! READ AND UNDERSTAND ALL
INSTRUCTIONS. Failure to follow all instructions listed
below and on the machine may result in electric shock,
fi re, and/or serious personal injury.
NOTE: Servicing of a product with double insulation
requires extreme care and knowledge of the system
and should be performed only by a qualifi ed service
technician. Always use original replacement parts as
listed in the Parts List pages of this manual.
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
See Figure 2.
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
exposed wires and cut or worn insulation.

ELECTRICAL

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
fi gure 2, 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!
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!
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.
PROPOSITION 65
WARNING!
power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paints
• crystalline silica from bricks and cement and other
masonry products
• arsenic and chromium from chemically-treated
lumber
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a
well ventilated area, and work with approved
safety equipment, such as those dust masks that
are specially designed to fi lter out microscopic
particles.
