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 appropriate 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.)
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
4. Tools marked “Double Insulated” do not require grounding.
They have a special double insulation system which satisfies
OSHA requirements and complies with the applicable standards
of Underwriters Laboratories, Inc., the Canadian Standard
Association, and the National Electrical Code. (See Figure B.)
5. Double insulated tools may be used in either of the 120 volt
outlets shown in the following illustration. (See Figure B.)
