of electric shock. (See 3-prong plug
and Outlet.)
2. The grounding prong in the plug is
connected through the green wire in-
side 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
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 Labora-
tories, Inc., the Canadian Standard
Association, and the National Electri-
cal Code. (See Outlets for 2-prong
plug.)
SKU 66672 For technical questions, please call 1-800-444-3353.
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 exten-
sion cords with inadequately sized
wire causes a serious drop in voltage,
resulting in loss of power and pos-
sible tool damage.
(See Table A.)
3. The smaller the gauge number of the
wire, the greater the capacity of the
cord. For example, a 14 gauge cord
can carry a higher current than a 16
gauge cord. (See Table A.)
4. When using more than one exten-
sion cord to make up the total length,
make sure each cord contains at
least the minimum wire size required.
(See Table A.)
5. If you are using one extension cord
for more than one tool, add the
nameplate amperes and use the sum
to determine the required minimum
cord size. (See Table A.)
6. 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.
7. Make sure the extension cord is prop-
erly wired and in good electrical con-
