4.2 Risks associated with items catching/
getting entwined
- Wear suitable clothing. Do not wear loose clothing
or jewellery. Keep hair, clothing and gloves at a
safe distance from the air tool and moving parts.
Loose clothing, jewellery or long hair could catch
in moving parts. There is a risk of injury in this
case.
4.3 Risks during operation
- To avoid cutting your hands or other body parts,
avoid contact with the rotating spindle and
attached grinding wheel.
- When using the air tool, the operator's hands may
be exposed to potential risk of cuts, abrasions and
heat damage. To protect your hands, wear suit-
able gloves.
- The operator and maintenance staff must be
physically capable of handling the size, weight
and power output of the air tool.
- Make sure you hold the air tool correctly: since
you must be prepared to counter any standard or
unexpected movements, keep both hands ready.
- Ensure you stand in a safe position and keep your
balance at all times.
- Avoid accidental operation. If the air supply is
interrupted, switch off the air tool using the On/Off
switch.
- Only use lubricants that have been recommended
by the manufacturer.
- Wear personal protective equipment and always
wear safety glasses. By wearing personal protec-
tive equipment such as gloves, protective
clothing, a dust mask, non-skid safety shoes, a
safety helmet or ear protectors, to suit the type of
device and its use, you reduce the risk of injury.
Wearing this equipment is recommended.
- Remember that the machine starts up when you
press the On/Off switch and also that the moving
mounted tool is dangerous.
- Wear a safety helmet if carrying out work above
your head.
- Machine continues to run: after switching off the
machine, only set it down when the motor has
come to a standstill.
- During the abrasive cutting process, the tool must
be supported so that the cutting slit has the same
or an increasing width.
- If the abrasive gets stuck in a cutting slit, switch off
the grinder for abrasives and loosen the grinding
wheel. Before continuing operation, ensure that
the abrasive is properly secured and undamaged;
- Grinding wheels and parting grinder discs must
not be used for side grinding (except for the
grinding wheel for side grinding). Grinders for
abrasives must not be used at speeds above the
maximum circumferential speed of an abrasive;
- Make sure there is noone in the immediate
vicinity.
- Personal protective equipment such as appro-
priate gloves, apron and safety helmets must be
worn.
- Sparks emitted during the grinding process may
ignite clothing and cause severe burns. You must
therefore ensure that sparks do not come in
contact with clothing. Wear fire-resistant clothing
and make sure a bucket of water is always close
to hand.
4.4 Risks associated with recurring move-
ments
- When working with the air tool, you may experi-
ence an uncomfortable sensation in your hands,
arms, shoulders, neck or other body parts.
- Make sure you are in a comfortable position to
carry out work with the air tool, check that the tool
is held securely, and avoid any awkward positions
that make it difficult, for example, to keep your
balance. If carrying out work over an extended
period, the operator should change position occa-
sionally. This should help to avoid fatigue and any
unpleasant sensation.
- If the operator experiences persistent symptoms
such as feeling unwell, aches, pains or throbbing,
a prickling or burning sensation, loss of hearing, or
joint stiffening, these warning signs must not be
ignored. The operator should advise the employer
of these symptoms and consult a qualified doctor.
4.5 Risks associated with accessory parts
- Disconnect the air tool from the air supply before
the mounted tool or accessory part is secured or
replaced.
- Only use accessories that are designed for this
device and that fulfil the requirements and the
specifications listed in these operating instruc-
tions.
- Only use mounting tools that are in good condi-
tion. If accessories are defective, they may break
and be ejected during operation.
- Ensure that the dimensions of the abrasive match
those of the grinder for abrasives and the abrasive
fits on the spindle.
- Make sure that the thread type and thread size of
the abrasive precisely matches the thread type
and thread size of the spindle thread.
- You must ensure that the abrasive is properly
secured and adequately tightened before use; the
grinder for abrasives must be operated for at least
1 min in a secured position at no-load speed; the
machine must be switched off as soon as signifi-
cant vibration or any damage is identified; the
cause of these problems must be identified.
- By checking the dimensions and other important
data for the spindle, you can prevent the end of the
spindle from hitting the floor of the opening of cup
wheels, grinding cones or mounted points with
threaded inserts (to be fitted on machine spin-
dles);
- For abrasives supplied with reducing adapters or
sockets, or abrasives that are to be used with
reducing adapters or sockets, the user must
ensure that the reducing adapter or reducing
socket in question does not touch the front of the
clamping flange and that the clamping force
delivers sufficient rotational movement to prevent
the abrasive slipping.
- Where clamping flanges for different types and
sizes of the abrasives are provided, always attach
the correct clamping flange for the abrasive used.
- Avoid any direct contact with the mounted tool
both during and after use because it may be hot or
have sharp edges.
