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. Us-
ing extension cords with inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool damage. Refer to the
table shown to determine the required minimum wire size.
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.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be sure it is marked with
the suffi x “W-A” (“W” in Canada) to indicate that it is acceptable for
outdoor use.
• Be sure your extension cord is properly wired and in good electrical
condition. Always replace a damaged extension cord or have it repaired
by a qualifi ed person before using it.
• Protect your extension cords from sharp objects, excessive heat and
damp or wet areas.
GROUNDING EXTENSION CORDS
Grounded Tools:
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 properly grounded
outlet (See Figure A). 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.
The grounding prong in the plug is
Improperly connecting the grounding wire can result
in the risk of electric shock. Check with a qualifi ed
electrician if you are in doubt as to whether the outlet
is properly grounded. Do not modify the plug provided
with the tool. Never remove the grounding prong from
the plug. Do not use the tool if the cord or plug is dam-
aged. If damaged, have it repaired by a MILWAUKEE
service facility before use. If the plug will not fi t the
outlet, have a proper outlet installed by a qualifi ed
electrician.

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.
Your 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 Figure A.
Double Insulated Tools:
Tools with Two Prong Plugs
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. Double
Insulated tools may be used in either
of the 120 volt outlets shown in Figures
B and C.
