GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualfified 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 on page 6.)
5. Double insulated tools may be used in either of the 120 volt outlets shown in the
preceding illustration. (See Figure B on page 6.)
