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.
Warning
grounding 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 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 fit the outlet,
have a proper outlet installed by a qualified
electrician.
Some models are provided with a 20 amp locking
plug (NEMA L5-20).
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 Figures A and B). 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.
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.

INSTRUCTIONS FOR FUTURE USE.
Improperly connecting the

exTension cords

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 parti-
cles.
grounding
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 at-
tached to an electrically "live"
terminal.
Your tool must be plugged into
an appropriate outlet, properly
installed and grounded in ac-
cordance with all codes and
ordinances. The plug and outlet
should look like those in Figures A and B.
Double Insulated Tools:
Tools with Two Prong Plugs
Tools marked "Double Insulated" do not require
grounding. They have a special double insu-
lation system which satis-
fies OSHA requirements and
complies with the applicable
standards of Underwriters
Laboratories, Inc., the Cana-
dian Standard Association and
the National Electrical Code.
Double Insulated tools may
be used in either of the 120 volt outlets shown in
Figures C and D.
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.
