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, reduc-
ing 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 accor-
dance 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.)
