Entanglement Hazards
Entanglement hazard can cause choking, scalping and/or lacerations if loose clothing, jewelry, hair or gloves are not kept away from the tool or accessories.
Work-related hazards
To prevent cutting of hands and other body parts, avoid contact with the rotating spindle and insertion tool. Using the tool can expose the operator's hands to hazards such as crushing, impact, shearing, abrasion, and heat. Appropriate gloves should be worn to protect hands. The operator and maintenance personnel should be physically capable of handling the volume, weight, and power of the tool. Hold the tool correctly. Be prepared to resist normal or unexpected movements and keep both hands available at all times. Maintain balance and a safe footing. Wear safety glasses; close-fitting gloves and protective clothing are recommended. Do not operate the rotary file at speeds exceeding the rated speed. Wear a safety helmet when working overhead. Be careful because the insertion tool continues to rotate for some time after the trigger is released. Depending on the material being processed, consider explosion or fire hazards.
Hazards associated with repetitive movements
When using a pneumatic tool for repetitive work, the operator is likely to experience discomfort in the hands, arms, shoulders, neck, or other parts of the body. When using a pneumatic tool, the operator should adopt a comfortable posture that ensures proper foot positioning and avoid awkward or unbalanced postures. Changing posture during prolonged work will help avoid discomfort and fatigue. If the operator experiences symptoms such as persistent or recurring discomfort, pain, throbbing pain, tingling, numbness, burning, or stiffness, they should not ignore them, they should report them to their employer and consult a doctor.
Dangers associated with accessories
Disconnect the tool from the power source before changing the inserted tool or accessories.
Only use accessories and consumables of sizes and types recommended by the manufacturer. Do not use accessories of other sizes and types. Avoid direct contact with the inserted tool during and after use; it may be hot or sharp.
Verify that the maximum operating speed of the inserted tool is greater than the rated speed of the grinder or polisher. Verify that the maximum operating speed of the inserted tool is greater than the rated speed of the tool. Never mount an abrasive wheel, cutting wheel, or cutter on a grinder. A damaged grinding wheel can cause serious injury or death. Do not use cracked or broken wheels, or wheels that have been dropped. Use only approved inserted tools with the correct shank diameter. Note that the rotational speed of the mounting point must be reduced due to the increased shaft length between the end of the sleeve and the mounting point. Ensure that the minimum length of the shank clamped in the tool holder is at least 10 mm (also consider the recommendations of the insert tool manufacturer). Avoid errors when matching the shank diameter of the inserted tool and the air tool clamp.
Workplace hazards
Slips, trips, and falls are major causes of injury. Beware of slippery surfaces caused by tool use and tripping hazards caused by air lines. Proceed with caution in unfamiliar surroundings. Hidden hazards may exist, such as electricity or other utility lines. The air tool is not intended for use in explosive atmospheres and is not insulated from contact with electricity. Ensure there are no electrical wires, gas pipes, etc., that could cause a hazard if damaged by the tool.

Hazards related to fumes and dust
Dust and fumes generated by using a pneumatic tool can cause ill health (for example, cancer, birth defects, asthma, and/or dermatitis). Risk assessment and implementation of appropriate control measures for these hazards are essential. The risk assessment should include the impact of dust generated by the tool and the potential for stirring up existing dust. Air exhaust should be directed to minimize dust agitation in a dusty environment. Where dust or fumes are generated, priority should be given to controlling them at the source. All integrated features and equipment for collecting, extracting, or reducing dust or fumes should be properly used and maintained in accordance with the manufacturer's recommendations. Respiratory protection should be worn in accordance with the employer's instructions and in accordance with health and safety requirements. The pneumatic tool should be operated and maintained in accordance with the instructions in the user manual to minimize fume and dust emissions. Select, maintain, and replace insertion tools as recommended in the user manual to prevent fume and dust buildup. Processing certain materials can create fumes and dust that can create an explosion hazard.
Noise hazard
Unprotected exposure to high noise levels can cause permanent and irreversible hearing loss and other problems, such as tinnitus (ringing, buzzing, whistling, or humming in the ears). Risk assessment and implementation of appropriate control measures for these hazards are essential. Appropriate controls to reduce risk may include measures such as: using mufflers to prevent workpiece „ringing." Wear hearing protection in accordance with your employer's instructions and in accordance with health and safety requirements. Air tool operation and maintenance should be carried out according to the instructions in the operating manual to avoid unnecessary increases in noise levels. If the air tool has a muffler, always ensure it is properly fitted during use. Select, maintain, and replace worn and inserted tools according to the operating manual's recommendations. This will prevent unnecessary increases in noise levels.
Vibration hazard
Exposure to vibration can cause permanent damage to the nerves and blood supply to the hands and arms. Keep hands away from screwdriver sockets. Dress warmly when working in cold temperatures and keep your hands warm and dry. If you experience numbness, tingling, pain, or skin whitening in your fingers or palms, stop using the pneumatic tool, inform your employer, and consult a doctor. Operating and maintaining the pneumatic tool according to the instructions in the manual will help avoid unnecessary increases in vibration levels. Do not use worn or poorly fitting attachments, as this can significantly increase vibration levels. Select, maintain, and replace worn insertion tools according to the instructions in the manual. This will help avoid unnecessary increases in vibration levels. A shielded mounting should be used where possible. Where possible, support the weight of the tool with a stand, tensioner, or balancer. Hold the tool with a light but firm grip, taking into account the required reaction forces, as the vibration hazard is usually greater when the grip force is higher. An incorrectly mounted or damaged insertion tool may cause increased vibration levels.
Additional safety instructions for air tools
Warning: Pressurized air can cause serious injury.
Caution! Always place the tool in a safe place on a flat surface, turn off the air supply, relieve air pressure from the hose, and disconnect the tool from the air supply when: not in use, before changing accessories, or before making repairs.
Caution! Never direct the air flow at yourself or other people.
Maintain a safe workspace. Do not operate the tool in an area where there is no room to keep your hands safe.
Hose impacts can cause serious injury. Always inspect for damaged or loose hoses and couplings. Direct cold air away from hands. Do not use quick-disconnect couplings on the inlet of impact or air-hydraulic tools. Use threaded couplings made of hardened steel (or a material of equivalent strength). Whenever universal screw connections (claw couplings) are used, locking pins and safety couplers must be used to prevent damage to the connections between hoses and between the hose and the tool. Do not exceed the maximum air pressure specified for the tool. Air pressure is critical to safety and affects performance in torque-controlled systems and continuous-speed tools. In these cases, hose length and diameter requirements should be maintained. Never carry the tool by the hose.
OPERATING CONDITIONS
Ensure that the compressed air source can generate the proper operating pressure and provide the required airflow. If the supply air pressure is too high, a pressure reducer with a safety valve should be used. The pneumatic tool should be supplied through a filter and lubricator system. This ensures both air purity and lubrication with oil. The condition of the filter and lubricator should be checked before each use and, if necessary, cleaned or the lubricator should be refilled. This will ensure proper tool operation and extend its service life. When using additional holders or support stands, ensure that the tool is properly and securely attached.
