and cause severe burns. Make sure the sparks do not fall onto the clothing.
Wear fi reproof clothing and keep a bucket of water near you.
Hazards connected with repetitive movements
When using a pneumatic tool for work entailing repetitive movements, the
operator is exposed to the discomfort of hands, arms, shoulders, neck or
other parts of the body. When using a pneumatic tool, the operator should
take a comfortable posture to ensure the feet are correctly positioned and
avoid strange or unbalanced postures. The operator should change the
posture over a long period of time to avoid discomfort and fatigue. If the
operator experiences symptoms such as persistent or repeated discomfort,
pain, pulsating pain, tingling, numbness, burning or stiff ness, the operator
is required to report the symptoms to the doctor. The operator should not
ignore them, should tell the employer about it and consult a doctor.
Hazards connected with accessories
Disconnect the tool from the power supply before replacing the inserted tool
or accessory. Use accessories and consumables only in the sizes and types
recommended by the manufacturer. Do not use other types or sizes of acces-
sories. Make sure that the dimensions of the grinding wheel are compatible
with those of the grinder and that the grinding wheel fi ts the spindle of the
grinder. Make sure that the type and size of the grinding wheel thread match-
es the type and size of the spindle thread. Check the grinding wheel before
use. Do not use grinding wheels which have (presumably) been dropped or
are broken, have chipped fragments, are cracked or are otherwise damaged.
Before use, check that the grinding wheel has been correctly mounted and
tightened. Start the unloaded grinder for 1 minute in a safe position. Stop it
immediately if excessive vibration or other faults are observed, then investi-
gate the cause of the fault. Prevent the spindle tip from touching the bottom
of the bowls, cones or pivots with threaded holes intended for attachment
to machine spindles by checking their size and other data. If adapters or
reducing sleeves are supplied with the grinding wheel, the user must ensure
that the adapter or the sleeve does not come into contact with the face of the
fi xing fl ange and that the fi xing forces are suffi cient to prevent the wheel from
slipping during rotation. If the fi xing fl anges are supplied in several types or
sizes, always match the correct fl ange(s) to the grinding wheel used. Avoid
direct contact with the inserted tool during and right after work, as it can be
hot or sharp. Store and handle the grinding wheels with care taken in accord-
ance with the manufacturer’s instructions.
Hazards connected with the workplace
Slips, stumbles and falls are the main causes of injury. Beware of slippery
surfaces caused by using the tool, as well as tripping hazards caused by the
air system. Handle with care in an unfamiliar environment. There may be
hidden hazards, such as electricity or other utility lines. The pneumatic tool
is not intended for use in potentially explosive zones and is not insulated
from contact with electricity. Make sure that there are no electric cables,
gas pipes, etc. which could pose a risk in the case of damage with the tool.
Fumes and dust hazards
Dust and fumes from pneumatic tools can cause ill health (e.g. cancer, con-
genital malformations, asthma and/or dermatitis), it is necessary to: assess
the risks and implement appropriate control measures with regard to these
risks. The risk assessment shall include the impact of the dust generated
by the tool and the possibility of existing dust disruption. The operation and
maintenance of the pneumatic tool must be carried out in accordance with
the instructions in the instructions manual in order to minimise the emission
of fumes and dust. The air outlet shall be so directed as to minimise the dis-
ruption of dust in a dusty environment. Where dust or fumes are generated,
priority should be given to controlling them at the source of the emission. All
integrated functions and accessories for collecting, extracting or reducing
dust or fumes should be properly operated and maintained according to
the manufacturer’s recommendations. Select, maintain and replace tools
to be inserted in accordance with the instructions in order to prevent the
increase of fumes and dust. Use respiratory protection in accordance with
the employer’s instructions and in accordance with hygiene and safety re-
quirements. Working with certain materials generates dust and fumes that
can create a potentially explosive atmosphere.
Noise hazard
Exposure to high levels of noise can cause permanent and irreversible hear-
ing loss and other problems such as tinnitus (ringing, buzzing, whistling or
humming in ears). A risk assessment and the implementation of appropriate
control measures for these hazards are necessary. Appropriate controls to
reduce the risk may include measures such as silencing materials to prevent
the workpiece from “ringing”. Use hearing protection in accordance with the
employer’s instructions and in accordance with hygiene and safety require-
ments. The operation and maintenance of the pneumatic tool must be carried
out in accordance with the instructions in the manual in order to avoid an
unnecessary increase in noise levels. If the pneumatic tool has a silencer,
always make sure that it is installed correctly when using the tool. Select,
maintain and replace worn inserted tools in accordance with the instructions
in the manual. This will help avoid an unnecessary increase in noise.
Vibration hazard
Although the tools were designed to minimise the risks associated with vi-
bration emission, it was not possible to completely eliminate the vibrations
which may be the cause of residual risks. Improper use of the tool may
result in exposure to vibration. The value of the vibrations specifi ed in the
manual may not adequately represent the vibration level of the intended
use. Exposure to vibration can cause permanent damage to the nerves and
blood supply of the hands and arms. Wear warm clothes when working at
low temperatures and keep your hands warm and dry. If numbness, tingling,
pain or bleaching occurs in your fi ngers or hands, stop using the pneumatic
tool, then inform your employer and consult your doctor. The operation and
maintenance of the pneumatic tool must be carried out in accordance with
the instructions in the manual in order to avoid an unnecessary increase in
vibration levels. Select, maintain and replace consumables/inserted tools in
accordance with the instructions in order to prevent unnecessary increase
in vibration levels. Support the weight of the tool with a base, tensioner or
stabiliser, if possible. Hold the tool with a light but secure grip, taking into
account the required reaction forces, as the risk of vibration is usually great-
er when the clamping force is higher. Incorrect installation of the inserted
cutting tool can result in increased vibration levels.
Additional safety instructions for pneumatic tools
Pressurised air can cause serious injury:
- always disconnect the air supply, release the air pressure from the hose
and disconnect the tool from the air supply when not in use, before chang-
ing accessories or carrying out repairs;
- never point the air stream at yourself or anyone else.
Hitting with the hose can cause serious injury. Always check for damaged
or loose hoses and connectors. Whenever universal screwed connections
(dog connections) are used, safety pins and safety connectors must be
