gloves to protect your hands. The operator and the maintenance personnel should be physically able to cope with the quantity,
weight, and power of the tool. Hold the tool correctly. Keep your feet in balance and in a safe position. The pressure on the start
and stop device should be released in the event of a power failure. Use only the lubricants recommended by the manufacturer.
Avoid direct contact with the tool during and after work, as it can be hot. Protective goggles must be worn, and we recommend
wearing suitable gloves and protective clothing.
Hazards related to repetitive movements
When using a pneumatic tool for work entailing repetitive movements, the operator is exposed to the discomfort of hands, arms,
shoulders, neck, or other parts of the body. When using a pneumatic tool, the operator should take a comfortable posture to en-
sure the feet are correctly positioned and avoid strange or unbalanced postures. The operator should change the posture over a
long time to avoid discomfort and fatigue. If the operator experiences symptoms such as persistent or repeated discomfort, pain,
pulsating pain, tingling, numbness, burning, or stiff ness, they should not ignore them. The operator should inform the employer
and consult a physician.
Hazards connected with accessories
Disconnect the tool from the power supply before replacing the tool to be inserted or accessory. Use accessories and consuma-
bles only in the sizes and types recommended by the manufacturer. In the case of scalers, never use any chisels as hand tools,
where appropriate. They have been specially designed and heat-treated for use with non-rotating impact tools only. In the case of
scalers and crushers, never use dull chisels where appropriate, as they are subject to heavy loads and may break due to wear.
Using a blunt tool can increase vibration and therefore sharpened tools should always be used. In the case of scalers, where
appropriate, never cool hot tools in water, this may result in brittleness and premature wear. In the case of scalers, damage or
breakage of the tool, as appropriate, may result from misuse of the tool as a lever, e.g. when leveraging. It is better to work by
removing smaller pieces to avoid jams. Avoid direct contact with the tool to be inserted during and after work, it can be hot or sharp.
Hazards connected with the workplace
Slips, stumbles, and falls are the main causes of injury. Beware of slippery surfaces caused by using the tool, as well as trip-
ping hazards caused by the air system. Proceed with caution in an unfamiliar environment. Hidden hazards may exist, such as
electricity or other utility lines. The pneumatic tool is not intended for use in potentially explosive zones and is not insulated from
contact with electricity. Make sure that there are no electric cables, gas pipes, etc. which could pose a risk in the case of damage
with the tool.
Fumes and dust hazards
Dust and fumes from pneumatic tools can cause ill health (e.g. cancer, congenital malformations, asthma and/or dermatitis), it
is necessary to: assess the risks and implement appropriate control measures with regard to these risks. The risk assessment
shall include the impact of the dust generated by the tool and the possibility of existing dust disruption. The air outlet shall be so
directed as to minimise the disruption of dust in a dusty environment. Where dust or fumes are generated, priority should be given
to controlling them at the source of the emission. All integrated functions and accessories for collecting, extracting or reducing
dust or fumes should be properly operated and maintained according to the manufacturer's recommendations. Use respiratory
protection in accordance with the employer's instructions and in accordance with hygiene and safety requirements. The operation
and maintenance of the pneumatic tool must be carried out in accordance with the instructions in the instructions manual in order
to minimise the emission of fumes and dust. Select, maintain and replace tools to be inserted in accordance with the instructions
in order to prevent the increase of fumes and dust.
Noise hazard
Exposure to high levels of noise can cause permanent and irreversible hearing loss and other problems such as tinnitus (ringing,
buzzing, whistling or buzzing in ears). A risk assessment and the implementation of appropriate control measures for these haz-
ards are necessary. Appropriate controls to reduce the risk may include measures such as silencing materials to prevent the work-
piece from "ringing". Use hearing protection in accordance with the employer's instructions and in accordance with hygiene and
safety requirements. The operation and maintenance of the pneumatic tool must be carried out in accordance with the instructions
in the instructions manual in order to avoid an unnecessary increase in noise levels. If the pneumatic tool has a silencer, always
make sure that it is installed correctly when using the tool. Select, maintain and replace worn tools to be inserted in accordance
with the instructions in the manual. This will help avoid an unnecessary increase in noise.
Vibration hazard
Although the tools were designed to minimise the risks associated with vibration emission, it was not possible to completely
eliminate the vibrations which remain as residual risks. Improper handling of the tool can cause risks associated with vibration
exposure. The value of the vibrations specifi ed in the manual may not adequately represent the vibration level of the intended use.
Vibration exposure may result in permanent damage to the nerves and blood circulation in the hands and the arms. Wear warm
clothes when working at low temperatures and keep the hands warm and dry. If numbness, tingling, pain or bleaching occurs
in your fi ngers or hands, stop using the pneumatic tool, then inform your employer and consult your doctor. The operation and
maintenance of the pneumatic tool must be carried out in accordance with the instructions in the manual in order to avoid an un-
