SPECIFIC SAFETY RULES

Safety Warnings Common for Grinding, Sand-
ing, Wire Brushing or Abrasive Cutting-Off
Operations:

• This power tool is intended to function as a

grinder, sander, wire brushing or cut-off tool.
Read all safety warnings, instructions, illus-
tr ations and specifi cations provided with this
power tool. Failure to follow all instructions listed
below may result in electric shock, fi re and/or se-
rious injury

• Operations such as polishing are not recom-

mended to be performed with this power tool.
Operations for which the power tool was not de-
signed may create a hazard and cause personal
injury.

• Do not use accessories which are not specifi -

cally designed and recommended by the tool
manufacturer. 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 fl y apart.

• The outside diameter and the thickness of

your accessory must be within the capacity
rating of your power tool. Incorrectly sized ac-
cessories cannot be adequately guarded or con-
trolled.

• Threaded mounting of accessories must

match the grinder spindle thread. For acces-
sories mounted by fl anges, the arbour hole of
the accessory must fi t the locating diameter
of the fl ange. 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, back-
ing 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 undamaged accessory. After in-
specting and installing an accessory, posi-
tion 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. De-

pending on application, use face shield, safe-
ty 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 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 hear-
ing 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 the power tool by insulated gripping

surfaces only, when performing an operation
where the cutting accessory may contact hid-
den wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.

• 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 acces-
sory’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 kick-
back forces, if proper precautions are taken.

• Never place your hand near the rotating ac-

cessory. Accessory may kickback 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 snag-
ging 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 Specifi c 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 cannot
be adequately guarded and are unsafe.

• The grinding surface of centre depressed

wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot
be adequately protected.

• The guard must be securely attached to the

power tool and positioned for maximum safe-
ty, so the least amount of wheel is exposed
towards the operator. The guard helps to pro-
tect operator from broken wheel fragments, ac-
cidental contact with wheel and sparks that could
ignite clothing.

• Wheels must be used only for recommend-

ed applications. For example: do not grind
with the side of cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them
to shatter.

• Always use undamaged wheel fl anges that

are of correct size and shape for your se-
lected wheel. Proper wheel fl anges support
the wheel thus reducing the possibility of wheel
breakage. Flanges for cut-off wheels may be dif-
ferent 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 exces-

sive pressure. Do not attempt to make an ex-
cessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twist-
ing or binding of the wheel in the cut and the pos-
sibility 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
kickback may occur. Investigate and take cor-
rective 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 “pocket

cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kick-
back.

Safety Warnings Specifi c for Sanding Opera-
tions:
• Do not use excessively oversized sanding

disc paper. Follow manufacturers recommen-
dations, when selecting sanding paper. Larg-
er 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
overstress 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
work load 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 sand-

ing, sawing, grinding, drilling, and other construc-
tion 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, depend-

ing 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 fi lter out microscopic
particles.
