a safety helmet when working over the head. Risk to bystanders should also be taken into account. Make sure that the workpiece
is securely clamped. Do not operate the tool without making sure that an inserted tool stop is installed. To avoid injury, replace the
stop when it is worn, cracked, or deformed. Apply the tool securely to the workpiece before starting work.
Hazards connected with work
Using the tool can expose the operator's hands to hazards such as crushing, impact, cutting, abrasion and heat. Wear suitable
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 starter
and stop device shall 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 connected with 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 ensure
the feet are correctly positioned and avoid strange or unbalanced postures. The operator should change the posture over a long
period of 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, the operator is required to report the symptoms to the doctor. The
operator should not ignore them, should tell the employer about it and consult a doctor.
Hazards connected with accessories
Disconnect the tool from the power source before changing the inserted tool or accessory. Use accessories and consumables
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 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 inserted tool 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 tripping
hazards caused by the air installation. Handle with care in an unfamiliar environment. There may be hidden hazards, 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 pollution
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 risks
are necessary. Appropriate controls to reduce the risk may include measures such as silencing materials to prevent the workpiece
from "ringing". Use hearing protectors 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
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 inserted tools 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
