Employer or user should contact the manufacturer for replacement of the rating plate each time when it is necessary.
Hazards related to projected parts
Damage of processed object, accessories or even the working tool may project the item at high speed. Always use eye protection measures resistant to impacts. Use protection level in accordance with the task at hand. Make sure the processed object is securely fixed. Make sure that rotational speed of the tool does not exceed the speed specified by the manufacturer. Check on a regular basis. Check the speed without accessories installed, in accordance with the manufacturer’s instructions. Make sure that sparks and debris produced when operating the tool are not dangerous. Disconnect the device from power source before maintenance or changing an accessory. Consider also the risk for bystanders.

Entanglement hazards
Hazard related to entanglement may cause choking, scalping and/or cutting wounds when loose clothes, jewellery, hair or gloves are not kept at a safe distance from the tool or accessories.

Work related hazards
Tool operation may be hazardous to operator’s hands, e.g. by pinching, hitting, cutting, abrasion or burns. Wear appropriate gloves for hand protection. Operator and maintenance personnel must be physically fit to handle the weight and power of the tool. Hold the tool correctly. Be prepared to counter-act against normal or unexpected movements and always have both hands ready. Maintain balance and keep safe position of your feet. Release the pressure on start/stop element in case of power outage. Use only lubricating media recommended by the manufacturer. Use protective glasses, it is also recommended to wear well fitted gloves and protective clothes. Make sure the accessories do not work at speeds that exceed their rated speed. Wear helmet when working above your head. Be careful and watch out for rotating parts even after releasing the start and stop trigger. Make sure the material processing does not cause fire.

Hazards related to repetitive movements
When using a pneumatic tool for operation that involves repetitive moves, the operator is exposed to discomfort of hands, arms, shoulders, neck and other body parts. When using a pneumatic tool, keep comfortable body posture that ensures the right feet position and avoid uneasy or unbalanced body postures. Change your body posture when working for a long time, it helps to avoid discomfort and fatigue. When experiencing constant or recurring discomfort, pain, pulsating pain, tingling, numbness, burning sensation or stiffness, do not ignore the symptoms, inform your employer and consult a doctor.

Hazards related to accessories
Disconnect the tool from power supply before changing the working tool or an accessory. Avoid direct contact with the working tool just after operation, it may be sharp or hot. Use accessories and consumables only in sizes and types recommended by the manufacturer. Do not use accessories of other types or other sizes. Make sure the maximum operating speed of the working tool is higher than the rated speed of the device. Never install grinding wheels, grinding discs or mills on the grinder. Grinding disc cracking may cause serious body injuries or even death. Never use wheels with dents, damages or when dropped. Make sure to use tools with correct mounting diameter. Notice that speed allowed at installation point is lower due to increased shaft length between collet end and the installation point. Make sure that minimum installation length is 10 mm. Bear in mind the risks when the working tool diameter does not match the collet diameter.

Workplace related hazards
Slipping, tripping and falling are the main reasons of injuries. Avoid slippery surfaces when using the tool and tripping hazards caused by compressed air system. Be careful in unknown environment. There may be hidden dangers, such as electricity or other utility systems. The pneumatic tool is not designed for use in explosion hazardous areas and has no electric insulation. Make sure there are no electric wires, gas pipes etc. that may be dangerous when damaged with the tool.

Dusts and fumes related hazards
Dusts and fumes produced with the pneumatic tool may cause bad health condition (e.g. cancer, congenital defects, asthma and/or dermatitis), so the risk assessment is necessary, and implementation of appropriate control measures for the hazards. The risk assessment should include impact of dust produced with the tool and possibility to stir up and lift existing dust. Operate and maintain the pneumatic tool in accordance with the instruction manual, which allows to minimise unnecessary emission of vapours and dusts. Air outlet should be directed in a way to minimise stirring up dust in dusty environment. Wherever dust and fumes are produced, it is a priority to control the emission at the source. All integrated functions and equipment used for collection, extraction and reduction of dust or smoke should be used appropriately and maintained in accordance with the manufacturer’s guidelines. Select, maintain and replace working tools in accordance with the guidelines in the manual to prevent increased vapours and dusts production. Use respiratory tract protection in accordance with the employer instructions, as well as occupational health and safety rules. Processing certain materials produces dusts and fumes, which can form potentially explosive environment.

Noise hazards
Exposure to high noise without any protection may cause permanent and irreversible hearing loss and other problems, such as tinnitus (sensation of ringing, buzzing, whistling or humming in ears). Risk assessment is necessary, and implementation of appropriate control measures related to the hazards. Appropriate control aiming to reduce risks can include measures such as silencing materials to prevent “ringing” of processed piece. Use hearing protection in accordance with the employer instructions, as well as occupational health and safety rules. Operate and maintain the pneumatic tool in accordance with the instruction manual, which allows to prevent unnecessary increase of noise. Select, maintain and replace worn out working tools in accordance with the instruction manual. It will prevent unnecessary increase of noise. When the pneumatic tool is equipped with a muffler, always make sure it is installed properly when operating the tool.

Vibration hazards
Exposition to vibrations may cause permanent injuries of nervous and vascular systems in hands and arms. Wear warm clothes when working in low temperatures and keep your hands warm and dry. In case of numbness, tingling, pain or whiteness of skin on fingers or hands, stop using the pneumatic tool, inform your employer and consult a doctor. Operation and maintenance of the pneumatic tool in accordance with instruction manual allows to avoid unnecessary increase of vibrations. Select, maintain and replace consumables and working tools in accordance with the guidelines in the manual to prevent hazardous increase of vibrations. Support the tool weight with a stand, tensioner or with a balancer. Vibration hazards are usually higher with stronger hand grip, therefore hold the tool with light but firm grip, while considering reaction forces that may appear.

Incorrect installation of cutting tool may cause increase of vibration level.
Additional safety instructions regarding pneumatic tools Pressurised air may cause serious injuries:

  • always cut off air supply, release air pressure from the hose and disconnect the tool from air supply at all times, when the tool is not in use, before changing accessories or before repairs;
  • never direct air stream at yourself or another person.
    Hitting with a hose may cause serious injuries. Always inspect the equipment for damaged or loose hose and connectors. Make sure to direct cold air away from hands. Each time when universal rotation joints are used (claw couplings), use securing pins and securing fasteners that protect from damages between hoses and between a hose and the tool. Do not exceed maximum air pressure specified for the tool. Never carry the tool when holding by its hose.

USE
Before each use, check the tool for any signs of damage. The tool should be kept clean. Check that none of the pneumatic system components is damaged. If any damage is observed, replace it immediately with new undamaged system components. Before each use of the pneumatic system, dry the condensed moisture inside the tool, compressor and pipes.

Before installing, removing, replacing accessories, and before performing any maintenance, turn off the power source, drain the air from the hose, and disconnect the device from the hose.

The best results are provided by frequent but not excessive lubrication of the device. oil introduced into the place of compressed air connection, lubricates the internal parts of the device. It is recommended to use an automatic oiler in the network, although oiling can also be done manually, before starting work and after each hour of continuous operation. Only a few drops of oil are given at a time. Excess oil could accumulate in the device and be blown out with the exhaust air. USE ONLY THE OIL INTENDED FOR PNEUMATIC EQUIPMENT. Do not use oil with detergents or other additives, as this could cause accelerated wear of the sealing elements used in the device. dirt and water in the air being supplied are the main causes of wear on the pneumatic device. The use of an oiler and an air supply filter ensures better operation and longer life of the pneumatic device. The filter capacity should be adapted to the airflow demand specific to the device. Avoid direct contact with the tool inserted during and after work, it may be hot or sharp. Use accessories and consumables only in sizes and types that are recommended by the manufacturer. Do not use accessories of a different type or size. Check that the maximum insert tool speed is greater than the rated speed of the device.

Avoid sticking to the cutting blade or excessive pressure.
Do not make excessively deep cuts. Overloading the cutting blade increases its load and its tendency to stick or get stuck and thus the possibility of kickback or breakage of the blade.

Avoid the area in front of and behind the rotating cutting blade. Moving the cutting disc in the workpiece away from one another may cause that in the event of kickback, the power tool will spring back together with the rotating disc directly towards the user.

If the cutting blade is jammed or the work is interrupted, switch off the machine and wait until the blade stops completely. Never try to pull the still moving blade out of the cut as this may cause kickback. Detect and remove the cause of the jam.

Do not switch the device on again while it is in the material. Before cutting, the cutting disc should reach its full speed. Otherwise, the wheel may get caught, jump off the workpiece, or cause kickback.

Boards or large objects must be supported before processing to reduce the risk of kickback caused by a stuck blade. Large items may bend under their own weight. The workpiece should be supported on both sides, both near the cutting line and at the edge.

Use extreme caution when cutting holes in walls or operating in other invisible areas. A cutting disc that penetrates into the material can cause the tool to kick back when it comes across gas, water, electricity, or other lines.

Do not use too large sheets of sandpaper. When choosing the size of sandpaper, follow the manufacturer’s instructions. The sanding paper sticking out from the sanding pad can cause injury, as well as blocking or tearing the paper or kickback.

It should be taken into account that even with normal use, there are pieces of wire lost by the brush. Do not overload the wires by applying too much pressure. Airborne pieces of wire can easily break through thin clothing and / or skin. If the use of a guard is recommended, prevent brush contact with the guard. The diameter of the brushes for plates and pots can be increased by pressure and centrifugal forces.

ASSEMBLING AND ADJUSTING THE BLADE GUARD
The blade guard protects the operator against debris, accidental contact with the tool working or sparks. It should always be mounted with additional attention to that the covering part is facing the operator.

DISC INSTALLATION
For grinding or cutting wheels:

  • Lock the spindle with the key provided
  • Insert the special key (included) in the outer flange holes.
  • Turn the key – loosen and remove the outer flange.
  • Apply the blade so that it is pressed against the surface of the inner flange.
  • Screw on the outer flange and tighten slightly with a special wrench. Disassembly of the discs takes place in the reverse order to assembly. When mounting, the shield should be pressed against the surface of the inner flange and centrally mounted on its rolling.

INSTALLATION OF WORKING TOOLS WITH A THREADED HOLE Lock the spindle with the key provided
Remove the previously mounted working tool – if fitted.

Before mounting, remove both flanges – inner flange and outer flange. Screw the threaded part of the working tool onto the spindle and tighten slightly.
Dismantling of working tools with a threaded hole is in the reverse order to assembly.

MAINTENANCE
The most effective grinder operation is possible when the air supply line is equipped with an air oiler. When the grinder is supplied without an oiler, proceed with the following maintenance instructions.
Disconnect the grinder from the flexible hose. Introduce few drops of oil for pneumatic tools into the grinder inlet before each use of the tool and after each hour of continuous operation. Put few drops of oil into the grinder switch button mechanism. Press the button few times to distribute oil on cooperating surfaces.
Do not use oil with detergent or other additives, this may cause faster wearing of sealings in the grinder.
