GENERAL POWER TOOL SAFETY WARNINGS
WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, fi re and/or
serious injury. Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
ELECTRICAL SAFETY
WORK AREA SAFETY
• Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodifi ed plugs and matching outlets will
reduce risk of electric shock.
• Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
• When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use
of a cord suitable for outdoor use reduces the risk
of electric shock.
• If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the infl uence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
• Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
• Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your fi nger on the switch or energising power tools
that have the switch on invites accidents.
• Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
2
attached to a rotating part of the power tool may
result in personal injury.
• Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
• If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
POWER TOOL USE AND CARE
• Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
• Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
• Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
• Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits
etc., in accordance with these instructions,
taking into account the working conditions and
the work to be performed. Use of the power tool
for operations different from those intended could
result in a hazardous situation.
BA TTER Y T OOL USE AND CARE
• Recharge only with the charger specifi ed by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fi re
when used with another battery pack.
• Use power tools only with specifi cally desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fi re.
• When battery pack is not in use, keep it away
from other metal objects like paper clips,
3
coins, keys, nails, screws, or other small metal
objects that can make a connection from one
terminal to another. Shorting the battery terminals
together may cause burns or a fi re.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact
accidentally occurs, fl ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
SERVICE
• Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
SPECIFIC SAFETY RULES
• This power tool is intended to function as a
grinder, sander, wire brushing or cut-off tool.
Read all safety warnings, instructions, illustr 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 designed 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 accesso-
ries cannot be adequately guarded or controlled.
• The arbour size of wheels, fl anges, backing
pads or any other accessory must properly
fi t the spindle of the power tool. Accessories
with arbour holes 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 undamaged 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. De-
pending 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 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 the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hidden 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.
• 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-
4
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 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 frequent 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 guard must be securely attached to the
power tool and positioned for maximum safety, so the least amount of wheel is exposed
towards the operator. The guard helps to pro-
tect operator from broken wheel fragments and
accidental contact with wheel.
• 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 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 exces-
sive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twisting or binding 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 spinning 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 kickback. 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 kickback.
Safety Warnings Specifi c for Sanding Opera-
tions:
• Do not use excessively oversized sanding
disc paper. Follow manufacturers recommendations, 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
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 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, 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.

WARNING To reduce the risk of injury ,
the operator should be instructed in the use,
care and protection of grinding wheels.
Grinding Wheel Selection
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.
• correct accessory, wheel type and grit for the job.
Grinding is the cutting action of thousands of abrasive 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 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 of Grinding & Cut-Off Wheels
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 temperature, or come into contact with solvents or
wetness.
Grinding
When grinding, hold tool at a 5
constant pressure for a uniform fi nish. Too great an
angle causes concentrated pressure on small areas
which may gouge or burn work surface.

USING WIRE BRUSHES
WARNING Everyone in the area must
wear protective clothing and safety goggles
or face shields. Fatigued wires and residue
will fl y off the brush with considerable force,
causing potential for serious injury.
Wire brushes are useful for removing rust, scale,
burrs, weld slag, etc.
Always install wire cup brushes according to the
accessory manufacterer’s instructions.
Fig. 7
Wire Cup Brush
WARNING Because the wires on wire
wheel brushes are directed towards the operator, a guard must be used to protect the
operator when fatigued wires break.
When using a wire wheel brush, install guard according to "Installing/Removing Accessories".
Fig. 8
Guard
Wire
Wheel
Brush
T est 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).
WARNING Never exceed Maximum
Safe Operating Speed of brush. Do not use
a damaged brush or one that is functioning
improperly (throwing wires, out-of-balance,
etc.). These conditions increase the possibility of further brush failure and possible
injury. Discard and replace damaged brushes
immediately.
USING SANDING DISCS
Sanding Disc Selection
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 fi nishing.
Always begin with a coarse grit, using successively
fi ner grits to obtain the desired fi nish. See your
MILWAUKEE Electric Tool Catalog for a complete
list of sanding discs.
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.
Unique grit pattern is arranged in clusters for faster stock removal and cleaning. Ideal for removing
paint from cars, boats, etc. without clogging.
Lasts up to 3 times longer than Aluminum Oxide Discs. For general metal working. Ideal for
tough jobs.
Installing Backing Pad and Sanding Discs
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.

Sanding
Hold tool at 5° to 15° angle to ensure proper sanding pressure and control. Too great an angle will
result in too much pressure and could cause excessive 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 fi nish.

For best result use only this portion of disc
Cross Sanding
When fi 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. Finishing marks left from previous sanding are easily
seen and removed for a uniform fi nish. Failure to
cross sand when changing from a coarse disc to
a fi nishing disc may result in deep scratches and
circular marks.
Removing Welds or Hammer Marks
When removing welds or hammer marks, limit
coarse sanding to the immediate area. Use successively fi ner grits to smooth surface.
Finishing Metal
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 fi 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
