8ORIGINAL INSTRUCTIONS
EN
sure, that the object processed is attached securely. Do not work
with a tool without making sure that the limiter of tool inserted has
been installed. To avoid injuries, replace the limiter as soon as it
has been used, broken or deformed. Before the work rmly apply
the tool inserted to processed surface.
The threat associated with operation
A tool while operating may expose operator’s hands to threat
such as: crushing, hitting, cutting o, rubbing or heat. Wear prop-
er gloves to protect your hands. An operator and maintenance
sta should be physically capable to deal with number, weight
and power of the tool. Keep the tool the correct way. Keep bal-
ance and position of foot that guarantee your safety. Release the
pressure applied on start/stop device in case of power failure.
Use only lubricants that are recommended by the manufacturer.
Avoid direct contact with a tool inserted during and after com-
pletion of work, it may be hot. Use protective goggles, it is rec-
ommended to wear well matching gloves and protective clothes.
Threats associated with repeated movements
When using a pneumatic tool for a work consisting in repeated
movements, the operator is exposed to experiencing a discomfort
of palms, arms, neck or other body parts. In case of using a pneu-
matic tool, the operator should adopt comfortable position ensur-
ing proper foot posture and avoid strange posture or postures
not guaranteeing stability. An operator should change his posture
during prolonged work, this will help avoiding discomfort and fa-
tigue. If an operator is experiencing symptoms such as: long-term
or repeated discomfort, pain, pulsating pain, tingling, numbness,
burning or stiness, he should not ignore them, should tell about
that his employer and consult with a physician.
Threats associated with accessories
Disconnect the tool from power source before the replacement
of tool inserted or accessory. Use accessories and consumables
only in sizes and of types recommended by the manufacturer.
When appropriate, never use any chisels as hand tools in case
of hammers. They have been designed and subjected to heat
treatment with regard to use only with non-rotary impact tools.
When appropriate, in case of hammers and crushers, never use
blunt chisels, as they are subjected to big load and may break due
to fatigue of material. Use of blunt tool may increase oscillations
and that is why sharp tools should be used. In case of hammers,
when appropriate, never cool down the hot inserted tools in wa-
ter, this may result in brittleness and premature wear. In case of
hammers, when appropriate, damage or breaking of tool may
result from improper use of tool as a lever, e.g. when leveraging.
It is better to work by removing small fragments which will allow
avoiding jamming. Avoid direct contact with a tool inserted during
and after completion of work, it may be hot or sharp.
Threats associated with work place
Slipping, stumbling and falls are main causes of injuries. Avoid
slippery surfaces caused by using the tool, as well as risk of
stumbling caused by hoses with compressed air. Take care in
an unknown environment. There may exist hidden threats, such
as electricity or other utilities. Pneumatic tools are not designed
for use in areas exposed to explosion and are not isolated from
contact with electric power. Make sure, that there are no electric
conductors, gas pipes etc. that may pose a threat in case of any
damage caused by the tool.
Threats associated with vapours and dusts
Dust and vapours generated by use of pneumatic tool may cause
bad health condition (for example a cancer, birth defects, asth-
ma and/or skin inammation), indispensable are: risk assess-
ment and implementation of proper control measures in relation
to these threats. Risk assessment should include eect of dust
generated by tool and possibility of stirring the existing dust. Air
outow should be directed in such a way as to minimize stirring of
dust in dusty environment. In environment of dust or vapours, the
priority is to control them at the source of emission. All integrated
functionalities and accessories for collecting, extracting or mini-
mizing dust or smoke should be properly utilized and maintained
pursuant to manufacturer’s recommendations. Use respiratory
tract protectors, in accordance with employer’s instructions and in
compliance with hygiene and safety requirements. Operation and
maintenance of pneumatic tool should be carried out in accord-
ance with instructions contained in user manual, this will allow
minimizing the emission of vapours and dust. Select, maintain
and replace tools inserted in accordance with instructions of user
manual, to prevent increase in quantity of vapours and dust.
Threat of noise
Exposure to high level of noise may cause permanent and irre-
versible loss of hearing and other problems, such as noise in ears
(sounding, buzzing, whistling or humming in ears). Risk assess-
ment is indispensable, as well as implementation of appropriate
control measures in relation to these threats. Right controls in
order to minimize the risk may include activities such as: muing
materials that prevent “sounding” of object being processed. Use
ear protectors, in accordance with employer’s instructions and in
compliance with hygiene and safety requirements. Operation and
maintenance of pneumatic tool should be carried out in accord-
ance with instructions contained in user manual, this will avoid
unnecessary increase in noise level. If a pneumatic tool is tted
with a muer, always make sure that it is properly installed when
operating the tool. Select, maintain and replace worn-out inserted
tools used in accordance with instructions of user manual. This
will allow avoiding unnecessary noise increase.
Threats of oscillations
Exposure to oscillations may cause long-term damage of nerves
and blood vessels in hands and arms.
Dress warm clothes when working at low temperatures and keep
your hands warm and dry. In case of numbness, pain or whiten-
ing of skin of ngers and hand, stop using the pneumatic tool,
than inform your employer and consult with physician. Operation
and maintenance of pneumatic tool in accordance with instruc-
tions contained in user manual, will allow avoiding unnecessary
increase in oscillation level. Do not hold the tool inserted with your
free hand, this will increase exposition to oscillations. Grab the
tool lightly but securely, taking into account the required counter
forces, since the threat posed by oscillations is usually higher,
when the gripping force is higher. Hold additional handpieces
from central position and avoid putting pressure to the handpiece
until it stops. In case of crushers, remove smaller blocks of con-
crete to avoid jamming the tool. In case of crushers, move the
tool every few seconds. When displacing stop the tool since oscil-
lations reach high level if the tool inserted does not lean against
material that is being processed.
Additional safety instructions regarding the pneumatic tools
Compressed air may cause serious injuries:
- always cut o air supply, empty the hose from air pressure and
