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, below left.)
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, below left.)
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, below left.)

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, above right.)
5. Double insulated tools may be used in either of the 120 volt outlets shown in the upper
right illustration. (See Figure B, above right.)

GROUNDING
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.
