GROUNDING
WARNING
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 service facility before
use. If the plug will not fi t the outlet,
have a proper outlet installed by a
qualifi ed electrician.
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 prop-
erly 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.
Fig. A
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 con-
nected 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 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.

EXTENSION CORDS
Grounded tools require a three wire exten-
sion 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, 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 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.
READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE.
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.
