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, congenital 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 disruption 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 requirements. 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 hearing 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 requirements. 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 vibration 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 greater 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 changing 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 used to prevent damage to the
connections between the hoses and between the hose and the
tool. Do not exceed the maximum air pressure specifi ed for the
tool. Never carry the tool holding it by the hose.
Caution! Tool kickback towards the operator
The kickback of the tool towards the operator is caused by a
sudden reaction to a locked or clamped grinding wheel or other
accessory. Locking or clamping causes a rotating accessory to
stop suddenly, which results in the pneumatic tool rotating in
the opposite direction to the accessory rotation. For example, if
the grinding wheel is locked or clamped by the workpiece, the
edge of the grinding wheel which reaches the clamping point
can sink in the surface of the material, causing the grinding
wheel to escape or be ejected. The grinding wheel can also
escape towards or away from the operator, depending on the
direction of the grinding wheel movement at the clamping point.
The grinding wheels may also break in such conditions. The
tool kickback towards the operator is a result of misuse and/
or failure to follow the guidelines in the User Manual. This
occurrence can be avoided by following the instructions below.
Use a fi rm grip on the tool and the correct position of the body
and hands to withstand the forces generated by the kickback.
Always use an additional handle, if supplied with the tool, to
ensure maximum control during the kickback or any unexpected
rotation during the tool start. The operator will be able to control
the tool rotation or the kickback if appropriate precautions are
taken. Keep your hands away from rotating tool parts. The
rotating parts can come into contact with your hands, when
kicked back. Do not stand in the area where the tool may kick
back. The kickback will direct the tool in the opposite direction
to the direction of the grinding wheel rotation, at the clamping
point. Pay special attention when working near corners, sharp
edges, etc. Prevent the grinding wheel from jumping and being
jammed. When working corners or edges, there is an increased
risk of the grinding wheel jam, leading to a loss of control over
the tool or its kickback. Do not use cutting chain blades or
