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 3‑Prong Plug
and Outlet.)
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 3‑Prong Plug and Outlet.)
3. The 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
preceding illustration.
(See 3‑Prong Plug and Outlet.)
Double Insulated Tools:
Tools with Two Prong Plugs
Outlets for 2‑Prong Plug
1. 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.
2. Double insulated tools may be used in
either of the 120 volt outlets shown in the
preceding illustration.
(See Outlets for 2‑Prong Plug.)
Extension Cords
1. Grounded tools require a three wire
extension cord. Double Insulated
tools can use either a two or three wire
extension cord.
2. As the distance from the supply outlet
increases, you must use a heavier gauge
extension cord. Using extension cords
with inadequately sized wire causes a
serious drop in voltage, resulting in loss
of power and possible tool damage.
(See Table A on page <?>.)
3. If you are using an extension cord
outdoors, make sure it is marked with the
suffix “W-A” (“W” in Canada) to indicate it
is acceptable for outdoor use.
4. Protect the extension cords from sharp
objects, excessive heat, and damp or
wet areas
