Figure B
Use only accessories that are recommend-
ed by the manufacturer for your model.
Accessories that may be suitable for one
tool may become hazardous when used
on another tool.
Always attach grounded (3-prong) exten-
sion cords to grounded (3-hole) outlets. If
you must use an extension cord, be sure
that the gauge is large enough to carry
the amount of current necessary for your
power tool. If not, your tool may experi-
ence a loss of power, excessive voltage
drop or overheating. The smaller the gauge
number, the heavier the cord (see table
below).
EXTENSION CORDS
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
1. Tools marked “Double Insulated” do not
require grounding. They have a special double
insulation system which satisfies OSHA re-
quirements and complies with the applicable
standards of Underwriters Laboratories, Inc.,
the Canadian Standard Association, and the
National Electrical Code. (See Figure B.)
2. Double insulated tools may be used in either
of the 120 volt outlets shown in the following
illustration. (See Figure B.)
GROUNDING
WARNING: Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the power cord plug provided with the tool. Never
remove the grounding prong from the plug. Do not use the tool if the power cord or
plug is damaged. If damaged, have it repaired by a service facility before use. If the
plug will not fit the outlet, have a proper outlet installed by a qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1. Tools marked with “Grounding Required”
have a three wire cord and three prong
grounding plug. The plug must be connected
to a properly grounded outlet. If the tool
should electrically malfunction or break down,
grounding provides a low resistance path to
carry electricity away from the user, reducing
the risk of electric shock. (See Figure A.)
2. The grounding prong in the plug is connected
through the green wire inside the cord to the
grounding system in the tool. The green wire
in the cord must be the only wire connected
to the tool’s grounding system and must
never be attached to an electrically “live”
terminal. (See Figure A.)
3. Your tool must be plugged into an ap-
propriate outlet, properly installed and
grounded in accordance with all codes and
ordinances. The plug and outlet should look
like those in the following illustration. (See
Figure A)
