small abrasive or workpiece fragments. The
eye protection must be capable of stopping ying
debris generated by various operations. The dust
mask or respirator must be capable of ltrating
particles generated by your operation. Prolonged
exposure to high intensity noise may cause hear-
ing loss.
• Keepbystanders a safe distanceaway from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken accessory
may y away and cause injury beyond immediate
area of operation.
• Hold the power tool by insulated gripping
surfacesonly,whenperforminganoperation
wherethecuttingaccessorymaycontacthid-
den wiring. Contact with a “live” wire will also
make exposed metal parts of the power tool “live”
and could give the operator an electric shock.
• 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.
• Donotrunthepowertoolwhilecarryingitat
yourside.Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
• Regularlycleanthepowertool’sairvents.The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
• Donotoperatethepowertoolnearammable
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.
KickbackandRelatedWarnings
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 rm grip on the power tool and
positionyour body andarm to allowyou to
resist kickback forces.Always use auxiliary
handle,ifprovided,formaximumcontrolover
kickback or torque reaction during start-up.
The operator can control torque reactions or kick-
back forces, if proper precautions are taken.

Safety Warnings Specic for Grinding and
AbrasiveCutting-OffOperations:
• Useonlywheeltypesthatarerecommended
for your power tool and the specic guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot
be adequately guarded and are unsafe.
• Theguardmustbesecurelyattachedtothe
powertoolandpositionedformaximumsafe-
ty,so the least amountofwheel is exposed
towardstheoperator.
• Wheels must be used only for recommend-
ed applications. For example: do not grind
withthesideofcut-offwheel.Abrasive cut-off
wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them
to shatter.
• Always use undamaged wheel anges that
are of correct size and shape for your se-
lected wheel. Proper wheel anges support
the wheel thus reducing the possibility of wheel
breakage. Flanges for cut-off wheels may be dif-
ferent from grinding wheel 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.
AdditionalSafetyWarningsSpecicforAbra-
siveCutting-OffOperations:
• Donot“jam” thecut-offwheelorapplyexces-
sivepressure.Donotattempttomakeanex-
cessivedepthofcut.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
behindtherotatingwheel.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.
• Whenwheelisbindingorwheninterrupting

rective action to eliminate the cause of wheel
binding.
• Do not restart the cutting operation in the
workpiece.Letthewheelreachfullspeedand
carefullyre-enterthecut.The wheel may bind,
walk up or kickback if the power tool is restarted
in the workpiece.
• Supportpanelsoranyoversizedworkpieceto

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.
• Useextracautionwhenmakinga“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.
SafetyWarningsSpecicforSandingOpera-
tions:
• Do not use excessively oversized sanding
discpaper.Followmanufacturersrecommen-
dations,whenselectingsandingpaper.Larger
sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
Safety Warnings Specic for Wire Brushing

AdditionalSafetyWarnings
Your risk from these exposures varies, depend-
ing on how often you do this type of work. To re-
duce 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 lter out microscopic
particles.
• Maintain labels andnameplates. These carry
important information. If unreadable or missing,
contact your authorised MILWAUKEE® (tm)
dealer for a replacement label.
• 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.
The guard helps to
protect the operator from broken wheel fragments,
accidental contact with wheel and sparks that could
ignite clothing.
ADDITIONAL BATTERY SAFETY RULES
Warning To reduct the risk of fire,
personal injury, and product damage due to a
short circuit, never immerse your tool, battery
pack or charger in fluid or allow a fluid to flow
inside them. Corrosive or conductive fluids,

GrindingWheelSelection
Use grinding wheels, and accessories that are:
• correct size as written on tool’s nameplate.
• rated at or above the RPM listed on the tool’s
nameplate.
•
ofGrinding&Cut-OffWheels
Grinding/cut-off wheels should be protected from:
• wetness and extreme humidity
• any type of solvent
• extreme changes in temperature
• dropping and bumping
Grinding and cut-off wheels should be stored:
• in an organized way so wheels can be removed
without disturbing or damaging other wheels
• with their safety information
Grinding and cut-off wheels should NOT be
dropped, rolled or bumped.
Discard wheels that have been dropped, rolled,
bumped, subjected to extreme changes in tem-
perature, or come into contact with solvents or
wetness.
Grinding
When grinding, hold tool at a 5oto 15oangle, using
constant pressure for a uniform nish. Too great an
angle causes concentrated pressure on small areas
which may gouge or burn work surface.

USING WIRE BRUSHES
Wire brushes are useful for removing rust, scale,
burrs, weld slag, etc.
Always install wire cup brushes according to the
accessory manufacterer’s instructions.
Test wheel for balance and loose or damaged wires
by letting it spin for one minute before applying it
to the workpiece. During this time, no one should
stand in front of or in line with it.
Control pressure and surface contact between
wheel and workpiece. Too much pressure causes
over-bending of wires and heat build-up causing
premature wire breaking, rapid dulling and reduced
brush life. Instead of more pressure, try a wire wheel
with more aggressive cutting action (increased wire
size, decreased wire length or different brush type
(knot type vs.crimped wire type).
When using a wire wheel brush, install guard ac-
cording to "Installing/Removing Accessories".

correct accessory, wheel type and grit for the job.
Grinding is the cutting action of thousands of abra-
sive grains on the face of a grinding wheel. When
grinding metals such as steel and iron, choose an
aluminum oxide grinding wheel. Select a silicon
carbide grinding wheel for stone and concrete. Use
cotton reinforced wheels for non-ferrous metals.
Type 27 Reinforced 3.2mm(1/8") thick or less Cut-Off
Wheels are suited for small cut-off and shallow
notching operations only. Always handle wheels
carefully to avoid damage. Before installing any
wheel, always inspect it for cracks. If wheel is
cracked, discard it to prevent others from using it.
Care

AluminumOxide
For fast cutting, general purpose discs for most
metal jobs. Best for cold-rolled steel, stainless
steel or metals requiring tough, fast cutting, long
lasting abrasives.
AluminumZirconiaBi-Cut
Unique grit pattern is arranged in clusters for fast-
er stock removal and cleaning. Ideal for removing
paint from cars, boats, etc. without clogging.
Ceramic
Lasts up to 3 times longer than Aluminum Ox-
ide Discs. For general metal working. Ideal for
tough jobs.
SandingDiscSelection
Use sanding discs and accessories that are:
• correct size as written on tool’s nameplate.
• rated at or above the RPM listed on the tool’s
nameplate.
• correct accessory, wheel type and grit for the job.
Refer to the table below to select the correct type
of sanding disc for your job. Generally, use 24 or
36 grit for heavy stock removal; 50, 60, or 80 grit
for medium stock removal and 120 grit for nishing.
Always begin with a coarse grit, using successively
ner grits to obtain the desired nish.

InstallingBackingPadandSandingDiscs
1. Remove the battery pack.
2. Wipe the accessories, disc nut and spindle to
remove dust and debris. Inspect the parts for
damage. Replace if needed.
3. Slip backing pad onto spindle with at side away

5. To tighten, press the spindle lock button while
turning disc nut clockwise with the spanner
wrench provided.
6. To remove backing pad and sanding disc,
remove the battery pack and reverse the pro-
cedure.
Sanding
Hold tool at 5° to 15° angle to ensure proper sand-
ing pressure and control. Too great an angle will
result in too much pressure and could cause exces-
sive wear to the disc and workpiece. Too small an
angle will reduce control.
Use long, sweeping, side to side strokes, advancing
forward to produce the desired nish.
CrossSanding
When nishing a surface that has been prepared
by a coarse disc or wheel, sand at right angles
to the strokes made by the coarser disc. Finish-
ing marks left from previous sanding are easily
seen and removed for a uniform nish. Failure to
cross sand when changing from a coarse disc to
a nishing disc may result in deep scratches and
circular marks.
RemovingWeldsorHammerMarks
When removing welds or hammer marks, limit
coarse sanding to the immediate area. Use suc-
cessively ner grits to smooth surface.
FinishingMetal
Constantly move across the surface. Work faster on
curved surfaces where contact areas are smaller
and pressure is greater. Flat areas may appear at
the end of the stroke when pressure is too heavy.
Ease up on pressure at end of each stroke and
when reversing strokes.
Troubleshooting
Deep scratches and circular marks can result
from:
• Using too coarse a grit
• Using a partially glazed disc
• Dirt or loose metal on the workpiece
• Failure to sand across the grain when changing
from coarse to nishing discs
• Failure to use closed coated discs to reduce the
problem of grains working loose and scratching
the workpiece
Bluish discoloration of metal surface indicates:
• Excessive heat caused by circular motion in a
small area
• Excessive pressure
• Use of worn out or glazed discs
