Check whether the maximum speed of the inserted tool is greater than the rated speed of the tool. You should never mount a grinding wheel, cutting wheel or milling cutter on the tool grinding machine. The grinding wheel, which has been done damaged can cause very serious injury or death. Do not use cracked or broken wheels or wheels that have been dropped. Use only the allowed inserted tools of an appropriate diameter of the mandrel. Please pay attention, that the rotational speed of the installation point must be reduced due to the increase in the lshaft ength between the end of the sleeve, and the installation point. Make sure, that the minimum length of the mandrel which is clamped in the tool holder is at least 10 mm (you should also take into account the recommendations of the manufacturer of inserted tool). Beware of errors by adjusting the diameter of the mandrel of inserted tools and clamping of the pneumatic tool. Risks associated with the workplace Slips, trips and falls are the main causes of injuries. Beware of slippery surfaces caused by the use of tools, and threats of tripping caused by the pneumatic system. Proceed with caution in an unknown environment. There may be hidden threats, such as electricity or other utility lines. Pneumatic tool is not intended for use in potentially explosive atmospheres and is not isolated from contact with electricity. Make sure, that there are no electric wires, gas pipes, etc., that can cause a threat in the event of their damage by using the tool. Hazards arising from vapors and dust Dust and fumes caused by using a pneumatic tool can cause bad health condition (such as cancer, birth defects, asthma and/or infl ammation of the skin). There are necessary: a risk assessment and implementation of appropriate control measures in relation to those risks. The risk assessment should include the eff ect of dust created by using tools and the possibility of excitation of the existing dust. The air outlet must be aimed to minimize generating dust in a dusty environment. Where dust or fumes are created, priority should be to control them at the source of their emission. All integrated functions and equipment for collection, extraction or reduction of dust or fume should be properly operated and maintained in accordance with manufacturer’s recommendations. Wear suitable respiratory protective equipment, in accordance with the instructions of an employer and in accordance with the requirements of hygiene and safety. Service and maintenance of the pneumatic tool should be carried out according to the recom mendations of the manual, this will minimize the emission of fumes and dust. You should select, maintain and exchange inserted tools according to the manual, to prevent increase of and dust. Treatment of certain materials can cause fumes and dust, that produce a risk of explosion. Noise hazard Exposure, without any protection, for high noise levels can cause permanent and irreversible hearing loss and other problems, such as tinnitus (ringing, buzz, whistling or humming in the ears). It is necessary to perform the risk assessment and implement appropriate control measures in relation to those risks. The appropriate checks, performed in order to reduce the risk, may include activities such as: application of insulation materials to prevent the “ringing” of the workpiece. Use hearing protection in accordance with the instructions13

An improperly mounted or damaged inserted tool can cause an increase in vibration. Additional safety instructions for pneumatic tools Air under pressure can cause serious injury: - always shut off the air supply, drain hose of air pressure and detach tool from air supply, when it is not in use, before changing accessories or performing repairs; - never direct the air stream at yourself or anyone else. Hose hitting can cause serious injury. You should always check for damaged or loose hoses and fi ttings. Cold air should be directed away from the hands Every time when there are used universal screwed connection (claw couplings), you should apply the protecting pins and connectors against the possibility of damage to the connections between the hoses and between the hose and tool. Do not exceed the maximum air pressure specifi ed for the tool. Never carry the tool, by holding it by the hose. OPERATING CONDITIONS You should make sure that that the source of compressed air allows you to create the proper working pressure and that it provides the required air fl ow. In the case of a too high air pressure, a reducer should be used together with a safety valve. The pneumatic tool must be powered by the system of a fi lter and lubricator. This will ensure, at the same time, the air, which is pure and moistured by oil. The state of the fi lter and lubricator should be checked before each use, and possibly clean the fi lter or refi ll shortage of oil in the lubricator. This will ensure proper operation of the tool and will extend its service life. If you use any additional handles or supporting racks, you should make sure, that the tool is mounted correctly and securely. You should adopt an appropriate posture to counteract the normal or unexpected movement of the tool, caused by its torque. Be careful of your work surroundings, the grinder machine can easily cut through something. Do not use any grinding wheels and tools designed for grinding the their surface side, for cutting. Do not use any cutting wheels or wheels for milling. Self-mounting grinding wheels should be concentric located on the grinder pad. When you turn off the grinder, your should wait with its stacking, until a complete stop to the rotating tool. Before the installation of additional equipment, your should make sure the maximum speed of the equipment is higher than the speed of the grinder. Do not use any equipment with handles of other dimensions than those specifi ed in the instructions. Insert tool must be fi rmly and securely mounted in the tool holder. Do not use reduction rings and sleeves, in order to match the diameter of the tool spindle and grinding wheel. Abrasive element of the getting wheel should be stored and used in accordance with its manufacturer’s instructions. Do not use damaged equipment. Equipment with any faults must be replaced immediately to new and effi cient. Check the status of the spindle and tool holders for wear or damage. Do not operate the grinder in a place with a high risk of explosion. The sparks, which are produced during operation, can cause a fi re. After mounting the grinding wheel you should run it for about 30 seconds in a safe position. Immediately stop the device, if you observe a large vibration or other defects in the grinder behavior. Any irregularities must be removed before the next launch of the grinder. You should make sure that the grinding speed is not greater than the speed which is specifi ed on the rating plate. During processing of certain materials, poisonous or combustible dusts and fumes can be created. Work in well ventilated areas and use personal protective equipment. When you are selecting safeguard measures you should take into account the type of workpiece. You should make sure, that sparks and debris created during operation do not cause any hazards.14

ORIGINAL INSTRUCTIONS Use personal protective equipment such as gloves, apron, helmet. In the case of dropped tools with a mounted grinding wheel, before subsequent switching it on, you should carefully check the condition of the grinding wheel.

OPERATING OF THE TOOL

Before each use, you should check that none of the components of the product is damaged. If you notice any damage, you should replace the element immediately with new one, undamaged system component. Before each use of the the pneumatic system, you should dry the moisture condensed inside the tool, compressor and pipes. Connecting the tool to pneumatic system The fi gure shows the recommended connection of tool to the pneumatic system. Presented method will ensure the most effi cient use of tool, and also it will extend the service life of the tool. Let a few drops of oil with viscosity SAE 10 to the air intake. To the thread of air inlet you should tightly and fi rmly screw the appropriate tip allowing for the connection of air supply hose. (II) On the tool driver you should mount an appropriate tipl. When you work with pneumatic tools you should use only equipment designed to work with the impact tools. Set the desired direction of rotation. The letter F means, that the rotation is clockwise, letter R that the rotation is counter-clockwise. Where it is possible you can adjust the pressure (torque). Connect the tool to an air system by using the hose with an inner diameter of 10 mm / 3/8 “. Make sure, that the strength of the hose is at least 1.38 MPa. (III) Start the tool for a few seconds, making sure that it does not issue any suspicious sounds or vibrations. Starting and stopping the tool Caution! Before starting the pneumatic tool, make sure that the mounted inserted tool does not come into contact with any object or any body part. The tool is operated by means of a lever which opens the air valve and thus ensures the supply of compressed air to the tool drive. If the lever is equipped with a lock that pre- vents the lever from being accidentally pressed. Turn the lock, so that it is parallel to the lever, and then pull the lever towards the tool housing. This will start the tool. Allow the tool to reach its rated speed and only then start working. The tool stops when the pressure on the lever is released. The lever automatically returns to the rest position and the lock secures the lever. Please note that the inserted tool can still move for some time after. Do not put the tool away until the inserted tool has come to a complete standstill. Installation and replacement of equipment (IV) Make sure that the maximum speed of the equipment is higher than the speed of the grinder. You should follow the recommendations of manufacturers of grinding wheels in relation to their speed and the mandrel length, which should be mounted in the spindle. Grab the spindle and unscrew the mounting nut until the handle will allow for mounting of the equipment. Mount a piece of equipment, so at least 10 mm of the mandrel is located inside the spindle. By using keys, tightly and fi rmly screw the nut which is locking the spindle. Operation of the sander Choose the appropriate tool for a given operation mode. Before starting work, you must allow for grinding wheel to reach its full speed. Only the rotating grinding wheel should be applied to a workpiece. You should apply only such pressure to the tool, which is required for the material processing. Too much pressure can damage the grinding wheels and increase the risk of injuries. During work the sparks can occur and workpiece fragments of the workpiece can tear off . You should ensure that sparks and tear-off fragments would not create risks in the workplace. MAINTENANCE Never use gasoline, solvent, or any other fl ammable liquid to clean the tool. The vapors can be ignited, causing the tool explosion and serious injury.Solvents, which are used to clean the tool holder and the body, can cause seals softening. Thoroughly the tool before starting your work. In case of fi nding any irregularities in the tool operation, the tool you should be immediately disconnect from the pneumatic system. All the elements of the pneumatic system must be protected against contamination. Contamination, which entered the pneumatic system can damage the tool and other air system components.15

ORIGINAL INSTRUCTIONS Maintenance the tool before each use Disconnect the tool from the pneumatic system. Before each use, let a small amount of liquid preservative (e.g.. WD-40) through the air intake. Connect the tool to pneumatic system and run for about 30 seconds. This will distribute the liquid preservative inside the tool interior and will clean it. Again, disconnect the tool from the pneumatic system. Let small amount of oil SAE 10 to the inside of the tool, through the air inlet and the holes intended for this purpose. It is recommended to use oil SAE 10 intended for maintenance of pneumatic tools. Connect the tool and run it for a short time. Attention! WD-40 may not be used as an appropriate lubricating oil. Remove excess of oil, that spill out through the holes. Left oil may damage the tool seals. Other maintenance operations Before each use, you should check whether the tool shows any traces of damages. Drivers, tool holders and the spindles must be kept clean. Every 6 months or after 100 hours of operation, you must pass the tool for inspection by the qualifi ed personnel in the repair shop. If the tool was used without the application of recommended air supply system, you should increase the frequency of the tool inspections. Troubleshooting You should stop using the tool immediately after the disguardy of any fault. Work with a defective tool can cause injury. Any repair or replacement of tool components must be carried out by qualifi ed personnel in authorized repair facility. Failure Possible solution The tool has too slow rotations or it does not start Let a small amount of WD-40 through the air inlet. Run the tool for a few seconds. The blades may stick to the rotor. Run the tool for about 30 seconds. Lubricate the tool with small amount of oil. Attention! The excess of oil can cause a decrease in power of tool. In this case, you should clean the drive. The tool starts and then slows down The compressor does not provide proper air supply. The tool starts by the air collected in the tank of compressor. As the tank is emptying, the compressor has not kept pace with the refi lling of air shortages. Connect the device to a more effi cient compressor. Insuffi cient power Make sure that your hoses have an internal diameter of at least such as specifi ed in the table in point 3. Check the set point of pressure, whether it is set to the maximum value. Make sure that the tool is properly cleaned and lubricated. In the absence of results, submit the tool for repair. Worn tools are secondary raw materials - it is forbidden to dispose of them together wigh household waste, because they contain substances harmful to human health and the environment! Please actively support the cost-eff ective management of natural resources and environmental protection by passing the used equipment to the point of storage for worn out devices. To reduce the amount of disposed waste it is necessary to re-use them, recycle or recover in another form.16
