rotating wheel and run the power tool at maximum no load
speed for one minute. Damaged wheels will normally break
apart during this test time.
j) Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and shop apron capable of stopping
small abrasive or workpiece fragments. The eye protection
must be cap- able 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.
k) 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
wheel may fl y away and cause injury beyond immediate area of
operation.
l) Hold the power tool by insulated gripping surfaces only,
when performing an operation where the cutting accessory
may contact hidden wiring. Cutting accessory contacting a
live wire may make exposed metal parts of the power tool live
and could give the operator an electric shock.
m) Never lay the power tool down until the accessory has
come to a complete stop. The spinning wheel may grab the
surface and pull the power tool out of your control.
n) 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.
o) 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.
p) Do not operate the power tool near fl ammable materials.
Sparks could ignite these materials.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotating
wheel. Pinching or snagging causes rapid stalling of the
rotating wheel which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the wheel’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.
a) 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.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) Do not position your body in line with the rotating wheel.
Kickback will propel the tool in direction opposite to the wheel’s
movement at the point of snagging.
d) 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.
e) Do not attach a saw chain, woodcarving blade, segmented
diamond wheel with a peripheral gap greater than 10 mm
or toothed saw blade. Such blades create frequent kickback
and loss of control.
f) Do not jam the 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
binding of the wheel in the cut and the possibility of kickback or
wheel breakage.
g) 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 wheel from the cut while the
wheel is in motion otherwise kickback may occur.
Investigate and take corrective action to eliminate the cause of
wheel binding.
h) Do not restart the cutting operation in the workpiece. Let
the wheel reach full speed and carefully re-enter the cut.
The wheel may bind, walk up or kickback if the power tool is
restarted in the workpiece.
i) 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.
j) 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.
Additional Safety and Working Instructions
When grinding metal, fl ying sparks are produced. Take care that no
persons are endangered. Because of the danger of fi re, no
combustible materials should be located in the vicinity (spark fl ight
zone). Do not use dust extraction.
Avoid fl ying sparks and sanding dust hit your body.
Never reach into the danger area of the machine when it is
running.
Chips and splinters must not be removed while the machine is
running.
Immediately switch off the machine in case of considerable
vibrations or if other malfunctions occur. Check the machine in
order to fi nd out the cause.
Do not let any metal parts enter the airing slots - danger of short
circuit!
WARNING! Danger of burns! The wheel and workpiece will
become hot during use. Wear gloves when changing discs or
touching workpiece. Keep hands away from the grinding area at all
times.
Do not dispose of used battery packs in the household refuse or by
burning them. Milwaukee Distributors off er to retrieve old batteries
to protect our environment.
Do not store the battery pack together with metal objects (short
circuit risk).
Use only System M18 chargers for charging System M18 battery
packs. Do not use battery packs from other systems.
Never break open battery packs and chargers and store only in dry
rooms. Keep dry at all times.
Battery acid may leak from damaged batteries under extreme load
or extreme temperatures. In case of contact with battery acid wash
it off immediately with soap and water. In case of eye contact rinse
thoroughly for at least 10 minutes and immediately seek medical
attention.
Warning! To reduce the risk of fi re, personal injury, and product
damage due to a short circuit, never immerse your tool, battery
pack or charger in fl uid or allow a fl uid to fl ow inside them.
Corrosive or conductive fl uids, such as seawater, certain industrial
chemicals, and bleach or bleach containing products, etc., can
cause a short circuit.
WARNING This device contains a lithium button/
coin cell battery. A new or used battery can cause
severe internal burns and lead to death in as little as
2 hours if swallowed or enters the body. Always

WARNING
The vibration and noise emission level given in this information sheet has been measured in accordance with a standardized test given in
EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration and noise emission level represents the main applications of the tool. However if the tool is used for diff erent
applications, with diff erent accessories or poorly maintained, the vibration and noise emission may diff er. This may signifi cantly increase the
exposure level over the total working period.
An estimation of the level of exposure to vibration and noise should also take into account the times when the tool is switched off or when it
is running but not actually doing the job. This may signifi cantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the eff ects of vibration and/or noise such as: maintain the tool and the
accessories, keep the hands warm, organization of work patterns.
WARNING Read all safety warnings, instructions,
illustrations and specifi cations provided with this power tool.
Failure to follow all instructions listed below may result in electric
shock, fi re and/or serious injury.
Save all warnings and instructions for future reference.
CUT-OFF MACHINE SAFETY WARNINGS
a) The guard provided with the tool must be securely
attached to the power tool and positioned for maximum
safety, so the least amount of wheel is exposed towards
the operator. Position yourself and bystanders away from
the plane of the rotating wheel. The guard helps to protect
operator from broken wheel fragments and accidental contact
with wheel.
b) Use only bonded reinforced or diamond cut-off wheels for
your power tool. Just because an accessory can be attached
to your power tool, it does not assure safe operation.
c) 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.
d) 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 applied to these wheels may cause them to shatter.
e) Always use undamaged wheel fl anges that are of correct
diameter for your selected wheel. Proper wheel fl anges
support the wheel thus reducing the possibility of wheel
breakage.
f) Do not use worn down reinforced wheels from larger
power tools. Wheels intended for a larger power tool are not
suitable for the higher speed of a smaller tool and may burst.
g) The outside diameter and the thickness of your accessory
must be within the capacity rating of your power tool.
Incorrectly sized accessories cannot be adequately guarded or
controlled.
h) The arbour size of wheels and fl anges must properly fi t the
spindle of the power tool. Wheels and fl anges 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.
i) Do not use damaged wheels. Before each use, inspect the
wheels for chips and cracks. If power tool or wheel is
dropped, inspect for damage or install an undamaged
wheel. After inspecting and installing the wheel, position
yourself and bystanders away from the plane of the
