SAFETY INSTRUCTIONS
Safety Warnings Common for Grinding:
a) This power tool is intended to function as a grinder.
Read all safety warnings, instructions, illustrations and
specifications provided with this power tool. Failure to
follow all instructions listed below may result in electric
shock, fire and/or serious injury.
b) Operations as polishing, sandig, wire brushing or
cutting-off are not recommended to be performed with
this power tool. Operations for which the power tool was
not designed may create a hazard and cause personal
injury.
c) Do not use accessories which are not specifically
designed and recommended by the tool manufacturer.
Just because the accessory can be attached to your power
tool, it does not assure safe operation.
d) 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 fly apart.
e) 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.
f) The arbour size of wheels, flanges, backing pads or
any other accessory must properly fit 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.
g) 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.
h) 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 capable of stopping flying debris
generated by various operations. The dust mask or
respirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
i) 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 fly away and cause injury
beyond immediate area of operation.
j) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the cutting
tool 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.
k) Never lay the power tool down until the accessory
has come to a complete stop. The spinning accessory
WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised 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 emission level represents the main applications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase
the exposure level over the total working period.
An estimation of the level of exposure to vibration 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 significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work patterns.
may grab the surface and pull the power tool out of your
control.
l) 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.
m) 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.
n) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
o) 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.
a) Maintain a firm 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 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.
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 or
toothed saw blade. Such blades create frequent kickback
and loss of control.
Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended for your
power tool and the specific guard designed for the
selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
b) 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.
c) Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the
possibility of wheel breakage. Flanges for cut-off wheels
may be different from grinding wheel flanges.
d) 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.
Always wear goggles when using the machine. It is
recommended to wear gloves, sturdy non slipping shoes
and apron.
After switching off, the machine will not be idle immediately.
(After-running of the work spindle.) Allow the machine to
come to a stop before putting down.
Never reach into the danger area of the plane when it is
running.
Only use tools whose permitted speed is at least as high as
the highest no-load speed of the machine.
Check grinding tools before use. The grinding tool must be
properly mounted and turn freely. Perform a test run for at
least 30 seconds without load. Do not use damaged, out of
round or vibrating grinding tools.
When grinding metal, flying sparks are produced. Take care
that no persons are endangered. Because of the danger of
fire, no combustible materials should be located in the
vicinity (spark flight zone). Do not use dust extraction.
Due care should be taken that no sparks or sanding dust
flying from the workpiece come into contact with you.
The adjusting nut must be tightened before starting to work
with the machine.
Always use and store the grinding disks according to the
manufacturer's instructions.
The workpiece must be fixed if it is not heavy enough to be
steady. Never lead the workpiece to the grinding disk with
your hand.
Secure work. Use clamps or a vice to hold work. It’s safer
than using your hand and it frees both hands to operate tool.
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.
Do not dispose of used battery packs in the household
refuse or by burning them. Milwaukee Distributors offer to
retrieve old batteries to protect our environment.
Do not store the battery pack together with metal objects
(short circuit risk).
Use only System Milwaukee 28 V chargers for charging
System Milwaukee 28 V battery packs. Do not use battery
packs from other systems.
No metal parts must be allowed to enter the battery section
of the charger (short circuit risk).
Never break open battery packs and chargers and store
only in dry rooms. Keep dry at all times.
Remove the battery pack before starting any work on the
machine.
Make sure that the grinding tool is installed in accordance
with the manufacturer‘s instructions.
The size of the grinding tool must be suitable for the grinder.
For dusty operations, the machine‘s ventilation slits must be
kept clear. If necessary, switch off the power to the machine
and remove the dust. Use a non-metallic object for this,
taking care not to damage any of the inner parts.
