• Lower guard should be retracted manually
only for special cuts such as "plunge cuts"
and "compound cuts". Raise lower guard
by lower guard lever and as soon as blade
enters the material, the lower guard must be
released. For all other sawing, the lower guard
should operate automatically.
• Always observe that the lower guard is cov-
ering the blade before placing saw down on
bench or fl oor. An unprotected, coasting blade will
cause the saw to walk backwards, cutting whatever
is in its path. Be aware of the time it takes for the
blade to stop after switch is released.
• Do not use abrasive wheels with circular
saws. Dust and grit can cause lower guard to
hang up and not operate properly.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.

• 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 spe-
cially designed to fi lter out microscopic particles.

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 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 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 ap-
propriate 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 satisfi es OSHA requirements and
complies with the applicable standards of Un-
derwriters Laboratories, Inc.,
the Canadian Standard Asso-
ciation and the National Elec-
trical Code. Double Insulated

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 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.
