wear dust mask, hearing protectors, gloves
and work shop apron capable of stopping
small abrasive or workpiece fragments. The
eye protection must be capable of stopping
fl ying debris generated by various operations.
The dust mask or respirator must be capable of
fi ltrating 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 fl y away and cause injury beyond immediate
area of operation.
•
Hold power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring
or its own cord.
Cutting accessory contacting a
live wire may make exposed metal parts of the
power tool live and shock the operator.
•
Position the cord clear of the spinning acces-
sory.
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 ac-
cessory 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 fl ammable
materials.
Sparks could ignite these materials.
•
Do not use accessories that require liquid
coolants.
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 accessory. 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
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
•
Maintain a fi rm grip on the power tool and
position 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 kick back over your hand.
•
Do not position your body in the area where
power tool will move if kickback occurs.
Kick-
back 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
accessory.
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 fre-
quent kickback and loss of control.
Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations:
•
Use only wheel types that are recommended
for your power tool and the specifi c guard
designed for the selected wheel.
Wheels for
which the power tool was not designed can not
be adequately guarded and are unsafe.
•
The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed to-
wards the operator.
The guard helps to protect
operator from broken wheel fragments and ac-
cidental contact with wheel.
•
Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel.
Abrasive cut-off wheels
are intended for peripheral grinding, side forces ap-
plied to these wheels may cause them to shatter.
•
Always use undamaged wheel fl anges that are
of correct size and shape for your selected
wheel.
Proper wheel fl anges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheel fl anges.
•
Do not use worn down wheels from larger
power tools.
Wheel intended for larger power tool
is not suitable for the higher speed of a smaller
tool and may burst.
Additional Safety Warnings Specifi c for Abra-
sive Cutting-Off Operations:
•
Do not jam the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut.
Overstressing the wheel increases
the loading and susceptibility to twisting or bind-
ing of the wheel in the cut and the possibility of
kickback or wheel breakage.
•
Do not position your body in line with and
behind the rotating wheel.
When the wheel, at
the point of operation, is moving away from your
body, the possible kickback may propel the spin-
ning wheel and the power tool directly at you.
•
When wheel is binding or when interrupting
a cut for any reason, switch off the power
tool and hold the power tool motionless until
the wheel comes to a complete stop. Never
attempt to remove the cut-off wheel from the
cut while the wheel is in motion otherwise kick-
back may occur.
Investigate and take corrective
action to eliminate the cause of wheel binding.
•
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut.
The wheel may bind,
walk up or kickback if the power tool is restarted
in the workpiece.
•
Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back.
Large workpieces tend to sag under their
own weight. Supports must be placed under the
workpiece near the line of cut and near the edge
of the workpiece on both sides of the wheel.
•
Use extra caution when making a “pocketcut”
into existing walls or other blind areas.
The
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.
Safety Warnings Specifi c for Sanding Opera-
tions:
•
Do not use excessively oversized sanding disc
paper. Follow manufacturers recommenda-
tions, when selecting sanding paper.
Larger
sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
Safety Warnings Specifi c for Wire Brushing
Operations:
•
Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
over stress the wires by applying excessive
load to the brush.
The wire bristles can easily
penetrate light clothing and/or skin.
•
If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard.
Wire wheel
or brush may expand in diameter due to workload
and centrifugal forces.
Additional Safety Warnings
•
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.
