■
The exhaust air should be extracted so that the
minimum amount of dust is raised in an already
dusty environment .
■
If dusts or vapours are created, the main priority
must be to control these at the site of their re-
lease .
■
All machine components or accessories intend-
ed for collecting, extracting or suppressing air-
borne dust or vapours should be used and ser-
viced in accordance with the manufacturer's
instructions .
■
Consumables/machine tools should be select-
ed, 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 .
Hazards caused by noise
■
Excessive noise levels in conjunction with insuffi-
cient hearing protection may lead to permanent
hearing damage and other problems, such as
tinnitus (ringing, buzzing, whistling or humming
in your ears) . It is essential to carry out a risk
assessment with regard to these hazards and
implement corresponding control mechanisms .
■
Suitable control mechanisms include measures
such as the use of insulating materials to prevent
ringing noise from occurring on the workpieces .
■
Use ear protection equipment as per the instruc-
tions provided by your employer or as required
by health and safety regulations .
■
The non-rotary percussive tool must be operated
and maintained in accordance with the recom-
mendations contained in these instructions in
order to reduce any unnecessary increase of
the noise level .
■
The consumables and the machine tool should
be selected, maintained and replaced in ac-
cordance with the recommendations in these
instructions in order to avoid any unnecessary
increase of the noise level .

Hazards caused by vibrations
■
Vibrations can damage the nerves and cause
malfunctions to the blood circulation in the
hands and arms .
■
Wear warm clothing when working in a cold
environment and keep your hands warm and
dry .
■
If you notice that the skin of your fingers or
hands is becoming numb, tingles, hurts or shows
white discolouration, stop working with the
non-rotary percussive tool, notify your employer
and consult a doctor .
■
The non-rotary percussive tool is to be operated
and maintained in accordance with the recom-
mendations contained in this manual to reduce
any unnecessary increase of the vibrations .
■
Do not use your free hand to hold the machine
tool, as this will increase the impact of the vibra-
tions .
■
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 .
■
If you are using suspended handles, hold them
in the middle and avoid pushing the handles up
to the stops .
■
When working on concrete, use crushers to
knock out small parts to prevent the tool from
seizing .
■
Move the cutting tool of the crushers every few
seconds . Stop the crusher when lifting the tool
to change its position, as strong vibrations may
occur when pulling the machine up by the han-
dles .
■
To prevent injury, all worn, broken or bent parts
of the locking mechanism must be replaced
immediately .
