GROUNDED UNITS: HOISTS WITH 3- PRONG PLUGS
1. Units marked with “Grounding Required” have a 3-wire cord and 3-pronggrounding plug. The plug must
be connected to a properly grounded outlet. If the unit were to 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 hoist’s grounding
system and must never be attached to an electrically “live” terminal. (See Figure A.)
3. Your unit 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 UNITS: HOISTS WITH 2-PRONG PLUGS
4. Units marked “Double Insulated” do not require grounding. They have a special double insulation system
which satises 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.)
