WARNING
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
filter out microscopic particles.

EXTENSION CORDS
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, 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 suffix “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 qualified
person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.

GROUNDING
WARNING
Improperly connecting the ground-
ing wire can result in the risk of
electric shock. Check with a qualified electrician
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug pro-
vided 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 fit the outlet, have a
proper outlet installed by a qualified electrician.
Grounded Tools (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 mal
-
function 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 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 appro-
Fig. A
priate 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 (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
Fig. B Fig. C
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.
