below may result in electric shock, fire and/or serious
injury.
• Operations such as grinding, sanding, wire
brushing or cutting-off are not recommended to
be performed with this power tool. Operations for
which the power tool was not designed may create
a hazard and cause personal injury.
• Do not use accessories which are not specifically
designed and recommended by the tool manufac-
turer. Just because the accessory can be attached
to your power tool, it does not assure safe operation.
• The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than their
rated speed can break and fly apart.
• The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories can-
not be adequately guarded or controlled.
• Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the ac-
cessory must fit the locating diameter of the
flange. Accessories that do not match the mounting
hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
• Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for loose
or cracked wires. If power tool or accessory is
dropped, inspect for damage or install an undam-
aged accessory. After inspecting and installing
an accessory, position yourself and bystanders
away from the plane of the rotating accessory and
run the power tool at maximum no-load speed
for one minute. Damaged accessories will normally
break apart during this test time.
• Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of
stopping flying debris generated by various opera-
tions. The dust mask or respirator must be capable
of filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing loss.
• Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wear personal protective equipment. Fragments
of workpiece or of a broken accessory may fly away
and cause injury beyond immediate area of operation.
• Hold the power tool by insulated gripping sur-
faces only, when performing an operation where
the cutting tool may contact hidden wiring or its
own cord. Contact with a "live" wire may also make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
• Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning
accessory.
• Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the power
tool out of your control.
• Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into
your body.
• Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the housing
and excessive accumulation of powdered metal may
cause electrical hazards.
• Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
• Do not use accessories that require liquid cool-
ants. Using water or other liquid coolants may result
in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other ac-
cessory. Pinching or snagging causes rapid stalling
of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction
opposite of the accessory's rotation at the point of
the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the surface
of the material causing the wheel to climb out or kick
out. The wheel may either jump toward or away from
the operator, depending on direction of the wheel's
movement at the point of pinching. Abrasive wheels
may also break under these conditions.
Kickback is the result of power tool misuse and/or in-
correct operating procedures or conditions and can be
avoided by taking proper precautions as given below.
• Maintain a firm grip on the power tool and posi-
tion your body and arm to allow you to resist
kickback forces. Always use auxiliary handle, if
provided, for maximum control over kickback or
torque reaction during start-up. The operator can
control torque reactions or kickback forces, if proper
precautions are taken.
• Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
• Do not position your body in the area where
power tool will move if kickback occurs. Kickback
will propel the tool in direction opposite to the wheel's
movement at the point of snagging.
• Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the ac-
cessory. Corners, sharp edges or bouncing have a
tendency to snag the rotating accessory and cause
loss of control or kickback.
• Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickback and loss of control.
Safety Warnings Specific for Polishing Operations:
• Do not allow any loose portion of the polishing
bonnet or its attachment strings to spin freely.
Tuck away or trim any loose attachment strings.
Loose and spinning attachment strings can entangle
your fingers or snag on the workpiece.
Additional Safety Warnings
• Maintain labels and nameplates. These carry im-
portant information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
• Some dust created by power sanding,
WARNING
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.
