Grounded tools require a three wire extension
cord. Double insulated tools can use either
a two or three wire extension cord. As the
distance from the supply outlet increases,
you must use a heavier gauge extension cord.

ing in loss of power and possible tool damage.
Refer to the table shown to determine the
required minimum wire size.
Improperly connecting the grounding
wire can result in the risk of electric
shock. Check with a qualiﬁed electri-
cian if you are in doubt as to whether

cord or plug is damaged. If damaged,
have it repaired by a MILWAUKEE ser-

installed by a qualiﬁed electrician.
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. When using
more than one extension cord to make up
the total length, be sure each cord contains
at least the minimum wire size required. 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 wire size.

Tools with Three Prong Plugs
Tools marked “Grounding Required” have a
three wire cord and three prong grounding
plug. The plug must be connected to a prop-
erly grounded outlet (See FigureA). If the tool
should electrically malfunction or break down,
grounding provides a

Be sure your extension cord is prop-

condition. Always replace a damaged
extension cord or have it repaired by a
qualiﬁed person before using it.
7. Cord keeper
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.
8. Saw motor cord
Protect your extension cords from sharp
objects, excessive heat and damp or wet
Your tool must be plugged into an appropri-
ate outlet, properly installed and grounded in
accordance with all codes and ordinances.
The plug and outlet should look like those
in Figure A.

Double Insulated Tools:

Tools marked “Double Insulated” do not
require grounding. They have a special
