Exhaust air must be discharged in such a way
that the amount of dust being blown about in a
dusty environment is minimised.
If dust or vapours are generated, the principal
task must be to control them in the area where
they are released.
All machine mounting parts or accessories in-
tended to collect, extract or eliminate airborne
dust or vapours should be used and maintained
according to manufacturer instructions.
Select, maintain and replace consumables and
machine tools as recommended in these instruc-
tions to prevent an unnecessary increase in the
production of dust or vapours.
Use respiratory protection equipment as required
by labour- and health protection regulations.
Noise hazards
With inadequate ear protection the impact of
high noise levels may result in permanent hear-
ing damage, hearing loss and other problems,
e.g. tinnitus (ringing, whistling or buzzing in the
ear). It is imperative to perform a risk assessment
for these hazards and implement the respective
regulatory mechanisms.
Suitable regulatory mechanisms to minimise the
risk include measures such as using insulation
to prevent pinging sounds on work pieces.
Use ear protection as required by
labour- and health regulations.
The non-rotating, percussive machine must be
operated and maintained in accordance with
the recommendations within these instructions
to prevent an unnecessary increase in the noise
levels.
Select, maintain and replace consumables and
machine tools as recommended in these instruc-
tions to prevent an unnecessary increase in the
noise level.
If the non-rotating, percussive machine is equipped
with a silencer, always ensure it is available and
in good working order when using this machine.
Hazard due to vibration
Exposure to vibration may cause damage to
the nerves and disturb blood circulation in hands
and arms.
Wear warm clothing and keep your hands warm
and dry when working in cold environments.
If you notice the skin on your fingers or your
hand becoming numb, tingling, hurting or be-
coming white, stop working with the machine
and consult a physician.
The non-rotating, percussive machine must be
operated and maintained in accordance with the
recommendations within these instructions to pre-
vent an unnecessary increase in the vibration.
Do not hold the machine tool with your free
hand, as this will result in an increase in the
impact of vibration.
Hold the machine firmly, but not too tightly, main-
taining the necessary hand reaction forces, as
the vibration hazard typically increases when
firming the grip.
Hold attached handles at the centre and avoid
sliding the handles all the way in.
Additional safety instructions
for pneumatic machinery
Compressed air can result in serious injuries.
If the machine is not in use, always cut off the
air supply, depressurize the air hose and discon-
nect the machine from before replacing acces-
sories or when performing repairs.
Never direc the air flow at yourself or others.
Hoses flapping about can result in serious inju-
ries. Therefore always inspect hoses and their
fasteners for damage and a secure fit.
Direct cold air away from hands.
Do not use quick-disconnect couplers at the tool
intake. Only use connectors made from hard-
ened steel (or material with comparable impact
resistance) on threaded hose connections.
When using universal swivel couplings, always
use locking pins and use whip-check hose safety
cables for protection in the event the connection
between the hose and the machine or in between
hoses fails.
