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 con-
nected to a properly grounded
outlet (See Figure A). If the tool
should electrically
malfunction or break
down, grounding pro-
vides a low resistance
path to carry electricity away from the user,
reducing the risk of electric shock.
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.
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 with Two Prong Plugs
Tools marked “Double Insulated” do not require
grounding. They have a special double insula-
tion system which satisfi es OSHA requirements
and complies with the applicable standards of
Underwriters Laboratories, Inc., the Canadian
Standard Association
and the National Elec-
trical Code. Double
Insulated tools may be
used in either of the 120
volt outlets shown in
Figures B and C.
Fig. B Fig. C
Fig. A
Improperly connecting the grounding
wire can result in the risk of electric
shock. Check with a qualifi ed electri-
cian 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 damaged. If damaged,
have it repaired by a MILWAUKEE ser-
vice facility before use. If the plug will
not fi t the outlet, have a proper outlet
installed by a qualifi ed electrician.

Anti-Vibration System
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.
Using extension cords with inadequately sized
wire causes a serious drop in voltage, result-
ing 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 ex-
ample, 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 out-
doors, 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 prop-
erly 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.
