■
If dusts or vapours are created, the main priority
must be to control these at the site of their release.
■
All machine components or accessories intended
for collecting, extracting or suppressing airborne
dust or vapours should be used and serviced in
accordance with the manufacturer's instructions.
■
Consumables/machine tools should be
selected, maintained and replaced in accord-
ance 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.
Risks due to 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
accordance 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.
■
When working in a cold environment, wear
warm clothing 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
handles.
■
To prevent injury, all worn, broken or bent parts
of the locking mechanism must be replaced
immediately.
