The operator should tell the employer and consult a qualifi ed health professional. Accessory hazards Disconnect the sander or polisher from the energy supply before fi tting or changing the inserted tool or accessory. Avoid direct contact with the inserted tool during and after use, as it can be hot or sharp. Use only sizes and types of accessories and consumables that are recommended by the manufacturer of sanders or polishers; do not use other types or sizes of accessories or consumables. Grinding wheels and cutting-off tools shall not be used. Check that the maximum operating speed of the inserted tool (fl ap wheels, abrasive belts, fi bre discs, backing pads, etc.), is higher than the rated speed of the sander or polisher. Self-fi xing sander discs shall be placed concentrically on the supporting pad. Workplace hazards Slips, trips and falls are major causes of workplace injury. Be aware of slippery surfaces caused by use of the tool and also of trip hazards caused by the air line or hydraulic hose. The sander or polisher is not intended for use in potentially explosive atmos- pheres and is not insulated against contact with electric power. Ensure that there are no electrical cables, gas pipes, etc., which can cause a hazard if damaged by use of the tool. Dust and fume hazards Dust and fumes generated when using sanders and polishers can cause ill health (for example cancer, birth defects, asthma and/or dermatitis); risk assessment and implementation of appropriate controls for these hazards are es- sential. Risk assessment should include dust created by the use of the tool and the potential for disturbing existing dust. Oper- ate and maintain the sander or polisher as recommended in these instructions, to minimize dust or fume emissions. Direct the exhaust so as to minimize disturbance of dust in a dust-fi lled environment. Where dust or fumes are created, the priority shall be to control them at the point of emission. All integral features or accessories for the collection, extraction or suppression of airborne dust or fumes should be correctly used and maintained in accordance with the manufacturer’s instructions. Select, maintain and replace the consumable/inserted tool as recommended in the instruction handbook, to prevent an unnecessary increase in dust or fumes. Use respiratory protection in accordance with employer’s instructions and as required by occupational health and safety regulations. Noise hazards Exposure to high noise levels can cause permanent, disabling hearing loss and other problems, such as tinnitus (ringing, buzz- ing, whistling or humming in the ears). Therefore, risk assessment and implementation of appropriate controls for these hazards are essential. Appropriate controls to reduce the risk can include actions such as damping materials to prevent workpieces from “ringing”. Use hearing protection in accordance with employer’s instructions and as required by occupational health and safety regulations. Operate and maintain the sander or polisher as recommended in the instruction handbook, to prevent an unneces- sary increase in the noise level. Select, maintain and replace the consumable/inserted tool as recommended in the instruction handbook, to prevent an unnecessary increase in noise. If the sander or polisher has a silencer, always ensure it is in place and in good working order when the tool is being operated. Vibration hazards Exposure to vibration can cause disabling damage to the nerves and blood supply of the hands and arms. Wear warm clothing when working in cold conditions and keep your hands warm and dry. If you experience numbness, tingling, pain or whitening of the skin in your fi ngers or hands, stop using the sander or polisher, tell your employer and consult a physician. Operate and maintain the sander or polisher as recommended in the instruction handbook, to prevent an unnecessary increase in vibration levels. Hold the tool with a light but safe grip, taking account of the required hand reaction forces, because the risk from vibration is generally greater when the grip force is higher. Additional safety instructions for pneumatic power tools Air under pressure can cause severe injury:14 ORIGINAL INSTRUCTIONS

- always shut off air supply, drain hose of air pressure and disconnect tool from air supply when not in use, before changing accessories or when making repairs; - never direct air at yourself or anyone else. Whipping hoses can cause severe injury. Always check for damaged or loose hoses and fi ttings. Whenever universal twist cou- plings (claw couplings) are used, lock pins shall be installed and whipcheck safety cables shall be used to safeguard against possible hose-to-tool or hose-to-hose connection failure. Do not exceed the maximum air pressure stated on the tool. Never carry an air tool by the hose.

Make sure the source of compressed air permits to generate adequate operating pressure and guarantees the required airfl ow. In case of an excessive air pressure, it is required to use a reducer with a safety valve. The pneumatic tool must be powered through the fi lter and lubricator system. This will guarantee that the air will be clean and lubricated with oil. The conditions of the fi lter and the lubricator must be revised before each use. If necessary the fi lter must be cleaned and the lubricator fi lled with oil. This will guarantee a proper operation of the tool and prolong its life. Do not use grinding belts whose dimensions are diff erent from those indicated in the technical specifi cation. Before using the tool check the endless band. If any damage or wear is detected, use a new band. Make sure the arrow on the band coincides with the arrow on the grinder. Place the band parallel to the rollers of the grinder, so that it does not fall from the rollers during operation. During work wear protective goggles and anti-dust masks. It is also recommended to wear gloves and protective clothes. While processing certain materials toxic or infl ammable powder or vapours may be generated. Work must be realised in well- ventilated rooms and it is required to use individual protective means.

Before each use of the tool make sure no element of the pneumatic system is damaged. In case any damage is observed replace immediately the damaged elements of the system. Before each use of the pneumatic system, dry the humidity condensed inside the tool, the compressor and the conduits. Connecting the tool to the pneumatic system The drawing indicated the recommended manner of connecting the tool to the pneumatic system. The indicated connection will ensure the most eff ective operation of the tool, and prolong its life. Place a couple of drops of an SAE 10 oil in the air inlet. Connect safely and tightly to the air inlet thread an adequate tip, which permits to connect an air supply hose. (II) Place the grinder in a position which ensures the safest and most ergonomic operation, in accordance with the procedure de- scribed below. Place the band on the rollers in accordance with the procedure described below. Connect the tool to the pneumatic system, using a hose whose internal diameter is 10 mm / 3/8”. Make sure the minimum resist- ance of the hose is 1.38MPa. (III) Start the tool for a couple of seconds, and make sure it does not emit any suspicious sounds or vibrations. Positioning the grinder in the working position (IV) Loosen the rotation lock bolt and then turn the power transmission section of the grinder, so that safe and effi cient operation is ensured. Tighten the locking bolt so that it does not turn during operation. During operation check whether the bolt is tight from time to time. Attention! Make sure the set position does not imply any contact between the rotating parts with the body or the clothes of the operator. Installation of the grinding band Make sure the arrow on the band coincides with the arrow on the grinder. (V) Press the tightening roller until the lock is activated. (VI) Install the band starting at the power transmission roller and passing to the tightening roller. (VII) Release the lock of the tightening roller, which will permit to tighten the band. (VIII) Turn the band several times, and make sure it rotates freely and does not tend to fall from the rollers during operation. If necessary repeat the tasks until the band is properly installed. Work with the grinder Start the grinder and wait until the band has reached the full rotational speed. It is only allowed to place a rotating band at the processed material. Exert only such pressure on the tool which is required to process the material. Do not press the tightening roller too long and at15 ORIGINAL INSTRUCTIONS

the same time move it perpendicularly to the direction of rotation. This might cause the band to fall from the z rollers of the grinder, which in turn implies a risk of serious injuries. MAINTENANCE Do not ever use gasoline, solvents or any other infl ammable liquids to clean the tool. Vapours may ignite causing explosion of the tool and serious injuries. Solvents used to use the handle and the body of the tool may soften the sealing. Dry the tool thoroughly before work com- mences. In case any irregularities in the functioning of the tool are detected, the tool must be immediately disconnected from the pneumatic system. All the elements of the pneumatic system must be protected from dirt. Dirt inside the pneumatic system may damage the tool and other elements of the pneumatic system. Maintenance of the tool before each use Disconnect the tool from the pneumatic system. Before each use place a small quantity of maintenance liquid (eg. WD-40) into the air inlet. Connect the tool to the pneumatic system and start it for about 30 seconds. This will permit to distribute the maintenance liquid inside the tool and clean it. Disconnect the tool from the pneumatic system. Place a small quantity of a SAE 10 oil inside the tool through the air inlet and holes provided for this purpose. It is recommended to use a SAE 10 oil for maintenance of pneumatic tools. Connect the tool and start it for a while. Attention! A WD-40 oil must not be used as the proper lubricant. Wipe off the excess of oil which comes out of the outlets. Remaining oil might damage the sealing of the tool. Other maintenance tasks Before each use of the tool make sure there is no visible damage of the tool. Drivers, fi xtures and spindles must be kept clean. Every six months, or after 100 hours of operation, have the tool revised by qualifi ed personnel in a service workshop. If the tool was used without the recommended air supply system, the frequency of inspections must be increased. Trouble shooting Stop using the tool immediately, if any damage is detected. Working with a non-operational tool may cause injuries. Any repairs and replacement of the elements of the tool must be realised by qualifi ed personnel in a service workshop. Failure Possible solution The rotation of the tool is too low or the tool does not start Place a small quantity of a WD-40 grease in the air inlet. Start the tool for a couple of seconds. The blades might have stuck to the rotor. Start the tool for about 30 seconds. Lubricate the tool with a small quantity of oil. Attention! Excess of oil may cause a reduction of the power of the tool. In such cases the power transmission system must be cleaned. The tool starts and then slows down The compressor does not ensure a suffi cient air supply. The tool starts thanks to the air accumulated in the compressor tank. When the tank is being emptied, the compressor does not follow up. Connect the device to a more effi cient compressor. Insuffi cient power Make sure the internal diameter of the hoses is at least the once indicated in the technical specifi cation. Check whether pressure is set to the maximum value. Make sure the tool is properly cleaned and lubricated. If there are no results have the tool repaired. Spare parts Information regarding spare parts for pneumatic tools may be obtained from the manufacturer or their agent. Once work has been concluded, the casing, the ventilation orifi ces, the switches, the additional handle and the guards must be cleaned, e.g. with air jet (whose pressure must not exceed 0.3 MPa), with a brush or with a dry cloth, without using any chemicals or cleaning liquids. The tool and the handles should be cleaned with a dry and clean cloth. Old tools are recyclable – they must not be disposed of with household garbage, since they contain substances which are danger- ous for people and the environment! We ask for active assistance in effi cient management of natural resources and protection of the environment. Send the device to an adequate collection point. In order to reduce the amount of waste, it is necessary to reuse, recycle or recover it.16 ORIGINALANLEITUNG
