■
Use only the lubricants recommended by the
manufacturer.
■
Avoid direct contact with the machine tool
during and after use as it may be hot.
■
Suitable safety goggles must be worn; wearing
protective gloves and safety clothing is recom-
mended.
Hazards caused by repetitive
movements
■
Users of non-rotary, percussive tools may experi-
ence unpleasant sensations in their hands, arms,
shoulders, neck area or other body parts while
working with the tools.
■
Assume a comfortable position when working
with this non-rotary percussive tool, ensure that
you have a firm footing and avoid unfavourable
positions or positions in which it is difficult to
keep your balance. During work over extended
periods, the operator should change posture to
avoid discomfort and fatigue.
■
If the operator notices symptoms such as persis-
tent discomfort, throbbing, pain, tingling, burning
or stiffness, these warning indications should
not be ignored. The operator should tell his
employer and consult a qualified medical
practitioner.
Hazards caused by accessories
■
Disconnect the non-rotary percussive tool from
the power supply before attaching or replacing
the machine tool or accessory.
■
Use only accessories and consumables of the
sizes and types recommended by the manufac-
turer of the non-rotary percussive tool. Do not
use any other types or sizes of accessories or
consumables.
■
For hammers (if applicable): never use the chis-
els as hand tools. They are specially designed
for use in non-rotary percussive tools and heat-
treated accordingly.
■
For hammers and crushers (if applicable): never
use blunt chisels because they require excessive
pressure and may cause fatigue fractures. Blunt
tools can increase vibrations. Always use sharp
tools.

■
Never cool hot accessories in water when using
hammers (if applicable).
This can lead to brittleness and premature fail-
ure.
■
In the case of hammers (if applicable), misuse
of the tool as a lever may result in chipping,
chisel breakage or damage to the tool. Work in
smaller sections to avoid snagging.
■
Avoid direct contact with the machine tool during
and after use because it may be hot or have
sharp edges.
Hazards in the workplace
■
Slipping, tripping and falling are the main causes
of injuries in the workplace. Look out for surfaces
which could have become slippery through use
of the machine and for any tripping hazards
caused by air or hydraulic hoses.
■
Proceed with caution in unknown surroundings.
There may be concealed hazards in the form of
power cables or other supply lines.
■
The non-rotary percussive tool is not intended
for use in explosive atmospheres nor insulated
against contact with electrical power sources.
■
Ensure that there are no electric cables, gas
pipes, etc. that could cause a hazard if dam-
aged by using the machine.
Hazards caused by dust and vapours
■
The dust and vapours that are produced by
using a non-rotary percussive tool can be haz-
ardous to health (e.g. cause cancer, birth defects,
asthma and/or dermatitis). It is essential to carry
out a risk assessment with regard to these risks
and implement appropriate regulatory mecha-
nisms.
■
The risk assessment should include all dust
caused by the use of the machine and the existing
dust that may be kicked up at the same time.
■
The non-rotary percussive tool must be operated
and maintained in accordance with the recom-
mendations contained in this manual in order
to minimise the release of dust and vapours.
■
The exhaust air should be extracted so that the
minimum amount of dust is raised in an already
dusty environment.
