Additional safety instructions for pneumatic power tools
The following additional warnings (or equivalent) shall be given with all pneumatic assembly power tools for threaded fasteners. Air under pressure can cause severe injury:

• 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. Cold air shall be directed away from the hands. Do not use quick-disconnect couplings at tool inlet for impact and air-hydraulic impulse wrenches. Use hardened steel (or material with comparable shock resistance) threaded hose fi ttings.
• Whenever universal twist couplings (claw couplings) are used, lock pins shall be installed and whipcheck safety cables shall be used to safeguard against possible hose-to-tool and hose-and-hose connection failure.
• Do not exceed the maximum air pressure stated on the tool. For torque-control and continuous-rotation tools, the air pressure has a safety critical eff ect on performance. Therefore, requirements for length and diameter of the hose shall be specifi ed. Never carry an air tool by the hose.

CONDITIONS OF OPERATION
Make sure the source of compressed air may create appropriate working pressure and guarantee the required fl ow of the air. If the pressure of the air is too high, use a reduced with a safety valve. The pneumatic tool must be powered through a fi lter and a greaser. It will guarantee simultaneously cleanliness and lubrication of the air with oil. The state of the fi lter and the greaser must be checked before each use and, if necessary, the fi lter must be cleaned or the oil supplied in the greaser. It will guarantee proper operation of the tool and will prolong its durability. It is necessary to correctly adapt the reaction stick to a given task. In the case additional holders or supporting stands are used; make sure the tool has been correctly fi xed. Adopt a correct position that will allow you to react to normal or unexpected movements of the tool that may be caused by the turning moment. Do not keep hands or other parts of the body within the range of the reaction stick – it may lead to serious injuries. Wrenches and other inserted tools must be adapted to work with pneumatic tools. The inserted tools must be in good working order and must be cleaned and not damaged. Their size must fi t the dimensions of the collector. It is prohibited to modify the sockets of the wrenches or the collector.
OPERATION OF THE TOOL
Before each use of the tool, make sure that no element of the pneumatic system is damaged. If there are any damaged elements, they should be immediately replaced with new, faultless elements of the system. Before each use of the pneumatic system, dry the humidity that condensates inside the tool, the compressor and the clouds of dust.

Connection of the tool to the pneumatic system
The drawing shows the recommended manner of connection of the tool to the pneumatic system. The presented connection guarantees the most effective operation of the tool and will prolong its durability. Place a couple of drops of oil (of viscosity SAE 10) to the air inlet. Into the thread of the air inlet, turn strongly an appropriate terminal that makes it possible to connect an air supply hose. Install an appropriate terminal on the collector of the tool. During work with pneumatic tools, use solely the equipment approved for work with percussive tools. Adjust the correct direction of rotation. „F” indicates clockwise rotation, „R” – anticlockwise rotation. Where it is possible, adjust the pressure (turning moment). Connect the tool to the pneumatic system using a hose of internal diameter 3/8”. Make sure the resistance of the hose is at least 1.38MPa. Work with thimble percussive wrenches Before screwing with a wrench starts, place the screw or the nut on the thread manually (at least two turns). Make sure the size of the wrench is correct for the screwed element. A wrong size may be a cause of damage to the wrench, the screw or the nut. Unscrewing and tightening Adjust the pressure in the pneumatic system so as it does not exceed the maximum value for the given tool. Set up the appropriate direction of rotation for the tool (F – tightening, R – unscrewing), and the appropriate turning moment. Install an appropriate thimble wrench on the collector of the tool.

MAINTENANCE

Never use gasoline, solvents or another inflammable liquid to clean the tool. The fumes may ignite causing an explosion of the tool and serious injuries. Solvents used to clean the tool holder and the body of the tool may soften the tightening of the machine. Dry thoroughly the tool before you start working with it. If any irregularities in the functioning of the tool are detected, it must be immediately disconnected from the pneumatic system. All elements of the pneumatic system must be protected from dirt. Dirt in the pneumatic system may damage the tool and other elements of the pneumatic system. Maintenance of the tool before every use Disconnect the tool from the pneumatic system. Before each use of the tool, place a small amount of maintenance liquid (e.g. WD-40) through the air inlet. Connect the tool to the pneumatic system and start it for approximately 30 seconds. It will allow the spreading of the maintenance liquid inside the tool and cleaning it. Disconnect the tool from the pneumatic system again. Place a small amount of SAE 10 oil inside the tool through the air inlet and other appropriate holes. It is recommended to use SAE 10 oil whose purpose is the maintenance of pneumatic tools. Connect the tool and start it for a while. Attention! WD-40 cannot be used as appropriate lubricating oil. Wipe out the excess of oil that comes out through the outlets. If the oil is left, it may damage the tightening of the tool. Other maintenance actions Before each use of the tool, make sure there are no signs of damage on the tool. Collectors, tool holders, and spindles must be kept clean. Every six months, or every 100 hours of operation, send the tool for revision which must be realized by qualify ed personnel in the repair shop. If the tool was used without the recommended air supply system, increase the frequency of overhauls of the tool. Defects Stop the operation of the tool immediately if any defect in its functioning has been detected. Working with a damaged tool may be a cause of injuries. All repair and replacement of the elements of the tool must be performed by qualifi ed personnel in an authorized repair shop. Connect the key to the pneumatic system. Place the key with the thimble installed on the element to be unscrewed or tightened. Gradually release the trigger of the tool. Once the work has been concluded, dismantle the pneumatic system and perform appropriate maintenance of the tool.

Introduce a small amount of WD-40 through the air inlet. Start the tool for a couple of seconds. It is possible that the blades adhere to the rotor. Start the tool for approximately 30 seconds. Lubricate to tool with a small amount of oil. Attention! Excessive amounts of oil may cause a drop in the power of the tool. In such a case, clean the power transmission.
The tool starts but then slows down| The compressor does not provide an appropriate flow of air. The tool starts with the air collected in the tank of the compressor. While the tank is being emptied, the compressor cannot follow up by refilling the tank. Connect the tool to a more efficient compressor.

Insufficient power

| Make sure the inside diameter of the installed hoses is not lower than 3/8”. Check the regulator of pressure – pressure must be set at the maximum value. Make sure the tool is properly cleaned and lubricated. If there are no results, send the tool for repair.

Once the functioning has been concluded, the casing, ventilation slots, switches, additional handles, and protections must be cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances or cleaning liquids. Tools and handles must be cleansed with a clean cloth. Worn tools are recyclable waste – it is prohibited to dispose of them throwing them away along with domestic waste, since the tools contain substances that are harmful for people and the environment! We ask for your active assistance in the economic management of natural resources and protection of the natural environment by sending the tools to a worn tools disposal point. In order to reduce the quantity of waste that is disposed if, it is necessary to recycle them.
