resistance path to carry electricity away from the user, reducing the risk of electric
shock. (See 3-Prong Plug and Outlet.)
The grounding prong in the plug is connected through the green wire inside the 2.
cord to the grounding system in the machine. The green wire in the cord must be
the only wire connected to the machine’s grounding system and must never be at-
tached to an electrically “live” terminal. (See 3-Prong Plug and Outlet.)
Your machine must be plugged into an appropriate outlet, properly installed and 3.
grounded in accordance with all codes and ordinances. The plug and outlet should
look like those in the following illustration. (See 3-Prong Plug and Outlet.)

DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
Tools marked “Double Insulated” do not require grounding. They have a special 1.
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 Outlets for 2-Prong Plug.)
Double insulated machines may be used in either of the 120 volt outlets shown in 2.
the preceding illustration. (See Outlets for 2-Prong Plug.)
EXTENSION CORDS
Grounded1. machines require a three wire extension cord. Double Insulated ma-
chines can use either a two or three wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge 2.
extension cord. Using extension cords with inadequately sized wire causes a seri-
ous drop in voltage, resulting in loss of power and possible machine damage.
(See Table A.)
The smaller the gauge number of the wire, the greater the capacity of the cord. For 3.
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Table A.)
When using more than one extension cord to make up the total length, make sure 4.
each cord contains at least the minimum wire size required. (See Table A.)
