Hazards caused by flying parts
■ If a workpiece or accessory or even part of the
machine tool itself breaks, parts can be flung
out at high speeds.
■ Always wear shock-resistant eye protection when
operating the grinding machine for abrasive
media. The degree of necessary protection must
be evaluated separately for each individual
task.
■ You must ensure that the workpiece has been
securely fixed.
■ You must ensure that the abrasive media has
been safely attached to the grinding machine
for abrasive media.
■ You must ensure that the maximum operating
rotational speed of the abrasive media calculated in revolutions per minute is the same as
or higher than the rated spindle speed.
■ Ensure that the protective guard has been fitted,
that it is in good condition and properly fixed,
and that it is regularly checked.
■ It is possible that no protective guard is required
during internal grinding under the condition that
the workpiece encloses the abrasive media.
■ You must ensure that the clamping flange is be-
ing used in accordance with the manufacturer's
instructions and that it is in good condition, i.e.
without cracks and flaws, and that it is flat.
■ You must check to see whether the spindle and
spindle thread have become damaged or worn.
■ You must ensure that any sparks or ashes
produced during operation do not cause any
hazards.
■ Always disconnect the grinding machine from
the power supply before replacing the abrasive
media or servicing it.
Hazards caused by entanglement
■ Suffocation, scalping and/or cut wounds can
occur if loose clothing, jewellery, necklaces, hair
or gloves are not kept away from the machine
and its accessories.
Hazards during operation
■ Avoid contact with the rotating spindle and the
fitted grinding disc in order to avoid cuts to the
hands and other body parts.
■ When using the machine, the operator's hands
can be subject to hazards such as cuts, grazing
and heat. Wear suitable gloves to protect your
hands.
■ The operator and maintenance personnel must
be physically capable of handling the size, mass
and power of the machine.
■ Hold the machine correctly:
Be ready to counteract any normal or suddenly
occurring movements. Keep both hands ready
for use.
■ Ensure that your body is balanced and that you
have a secure standing position.
■ Release the start/stop control if there is a disrup-
tion to the power supply.
■ Use only the recommended lubricants.
■ Safety goggles must be worn; wearing of protec-
tive gloves and safety clothing is recommended.
■ Wear a safety helmet if working above head
height.
■ Do not put the machine down after switching
off until the disc has stopped rotating.
■ When abrasive cutting, the workpiece must be
supported so that the cutting slot has a constant
or increasing width during the entire cutting
process.
■ If the abrasive media jams in the cutting slot, the
grinding machine for abrasive media must be
turned off and the grinding disc must be loosened. Before continuing operation, check that
the abrasive media is still properly fixed and
has not been damaged.

■ Grinding discs and abrasive cutting discs may
not be used for side grinding (exception: grinding discs for side grinding). Grinding machines
for abrasive media may only be operated at a
rotation speed which is less than the abrasive
media maximum speed;
■ ensure that no persons are standing in the im-
mediate vicinity.
■ Personal safety equipment such as suitable
gloves, aprons and protective helmets must be
worn.
■ Sparks caused by grinding can ignite clothing
and cause serious burns. You must ensure that
sparks do not impact clothing. Wear fire-retardant clothing and ensure that there is a bucket of
water in the vicinity.
Risks due to repetitive movements
■ When using a grinding machine for abrasive
media to perform work-related activities, operators may experience uncomfortable sensations
in their hands and arms, as well as in the neck
and shoulders or other parts of the body.
■ When using a grinding machine for abrasive
media, the operator should adopt a comfortable posture whilst ensuring a secure hold
and avoiding awkward postures or positions
in which it is difficult to maintain balance. The
operator should change positions during the
course of long-lasting tasks. This can be helpful
in the prevention of discomfort and fatigue.
■ If the operator notices symptoms such as persis-
tent or recurring illness, discomfort, throbbing,
pain, tingling, burning or stiffness, these indications should not be ignored. In this case, the
operator should inform his/her employer and
consult a suitably qualified physician.
Hazards caused by accessories
■ Disconnect the grinding machine for abrasive
media from the power supply before fitting or
replacing the machine tools or accessories.
■ Use only accessories and supplies of the sizes
and types recommended by the manufacturer
of the grinding machine for abrasive media.
Never use any other types or sizes of accessory
parts and consumables.
■ Ensure that the dimensions of the abrasive me-
dia are compatible with those of the grinding
machine for abrasive media and that the abrasive media fits onto the spindle.
■ Ensure that the thread type and size of the
abrasive media exactly matches the thread type
and size of the spindle thread.
■ Always inspect the abrasive media before use.
Do not use any abrasive media which may
have been dropped or which shows signs of
splintering, cracking or other flaws.
■ Always ensure that the abrasive media has
been properly fixed and tightened firmly
enough before use; the grinding machine for
abrasive media must be operated at idling
speed for at least 1 minute in a safe location;
switch off the machine immediately if you notice
excessive vibration or any other damage; the
cause of these malfunctions must be determined.
■ Ensure that the spindle end does not contact the
bottom of the openings in cut wheels, grinding
cones or whetstones with thread inserts which
are intended for the attachment of machine
spindles, by checking the dimensions and other
important spindle data.
■ In the case of abrasive media which are sup-
plied with reducers or reducing bushings, or
which are intended for use with reducers or
reducing bushings, the operator must ensure
that the reducer or reducing bushing does not
contact the face of the clamping flange and that
the clamping force provides sufficient rotational
drive to prevent slipping of the abrasive media.
■ In cases in which clamping flanges for different
types and sizes of abrasive media have been
provided, always fit the correct clamping flange
for the abrasive media being used.
■ Avoid direct contact before and after use of the
machine tool since it can be hot or have sharp
edges.
■ The abrasive media must be handled and stored
in accordance with the manufacturer's instructions.

Hazards in the workplace
■ Slipping, tripping up and falling are the main
causes of injuries at the workplace. Look out
for surfaces which could have become slippery
through use of the machine, and also any tripping hazards caused by air or hydraulic hoses.
■ Proceed with caution in unknown surroundings.
Hidden hazards caused by power or other
supply lines may be present.
■ The grinding machine for abrasive media is not
intended for use in explosive atmospheres and
is not insulated against contact with electrical
power sources.
■ Ensure that no electrical service lines, gas pipes,
etc., which could cause a hazard if damaged
by use of the machine are present.
Risks due to dust and vapours
■ The dust and vapours produced by using the
grinding machine for abrasive media and polishing can be hazardous to health (e.g. cause
cancer, birth defects, asthma and/or dermatitis); it is essential to carry out a risk assessment
in respect of these risks and to implement corresponding regulatory mechanisms.
■ The risk assessment should include all dust
caused by the use of the machine and any
existing dust that may be whirled up at the
same time.
■ The grinding machine for abrasive media must
be operated and maintained in accordance
with the recommendations contained in this
manual to keep the release of dust and vapours
to a minimum.
■ The exhaust air should be routed so that the
raising of dust in already dusty environments is
kept to a minimum.
■ If dusts or vapours are created, the main priority
must be to control these at the site of their release.
■ All inserts or accessories of the machine in-
tended for collecting, extracting or suppressing
airborne dust or vapours or should be used and
serviced in accordance with the manufacturer’s
instructions.
■ Consumables/machine tools should be se-
lected, maintained and replaced in accordance
with the recommendations in this guide in order
to avoid unnecessary intensification of dust or
vapour production.
■ Use breathing equipment as per the instructions
provided by your employer or as required by
health and safety regulations.
■ Processing certain materials can cause emission
of dust and vapours which, in turn, can result in
the formation of an explosive environment.
Risks due to noise
■ Exposure to high noise levels can result in per-
manent hearing damage, loss of hearing and
other problems such as tinnitus (ringing, rushing,
whistling or buzzing in the ear) if sufficient hearing protection is not being worn.
■ Suitable regulatory mechanisms include meas-
ures such as the use of insulation materials to
avoid pinging occurring on the workpieces.
■ Use hearing protection.
■ The grinding machine for abrasive media is to
be operated and maintained in accordance
with the recommendations contained in this
manual to reduce any unnecessary increase
of the noise levels.
■ If the grinding machine for abrasive media is
equipped with a silencer, always ensure that
this in its place and is operational while the
machine is in operation.
■ Consumables/machine tools should be selected,
maintained and replaced in accordance with
the recommendations in this guide in order to
avoid unnecessary increase of the noise levels.

Risks due to vibrations
■ Vibrations can damage the nerves and cause
problems with the blood circulation in the hands
and arms.
■ When working in a cold environment, wear
warm clothing and keep your hands warm and
dry.
■ If you notice numbness, tingling or pain in your
fingers or hands or notice that the skin of your
fingers or hands has become pale, stop working with the grinding machine for abrasive media, inform your employer and consult a doctor.
■ The grinding machine for abrasive media must
be operated and maintained in accordance
with the recommendations contained in this
manual to reduce any unnecessary increase of
the vibrations.
■ Do not allow the machine tool to rattle against
the workpiece since this would very probably
result in a considerable increase in the vibrations.
■ Consumables/machine tools must be selected,
maintained and replaced in accordance with
the recommendations in this guide in order to
avoid any unnecessary increase in vibration.
■ Always use a stand, a clamp or a compensation
device to support the weight of the machine.
■ Hold the machine securely but not too firmly
while maintaining the necessary hand-reaction
force, as the vibration risk generally increases
the harder the machine is held.
■ Use intermediate layers if these are intended for
the bonded abrasive media.
Additional safety instructions for
pneumatic machines
■ Compressed air can cause serious injuries.
– Ensure that the air supply is switched off,
the hose is not under pressure and that the
machine is disconnected from the air supply
when not in use, and also before exchanging accessories or carrying out repairs.
– Never aim the airflow towards yourself or
any other person.
■ Thrashing hoses can cause serious injury. There-
fore, always check that the hoses and their fixings are not damaged or have not come loose.
■ If universal rotary joints (claw couplings) are
used, locking pins must be used to provide protection; Whipchek
used to provide protection in case of a failure of
the connection of the hose to the machine.
■ Ensure that the maximum permissible pressure
stated on the machine is not exceeded.
■ Never carry compressed air-powered machines
