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. (V)
Install an appropriate thimble wrench on the collector of the tool. (IV)
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.
MAINTENANCE
Never use gasoline, solvents or another infl ammable 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 spreading 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 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 quali-
fi 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 operation of the tool immediately if any defect in its functioning has been detected. Work 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.
