Unscrewing and screwing down
Adjust the pressure in the pneumatic system so that it does not exceed the maximum value for the tool. Set
the correct direction of rotation of the tool and the correct torque. Mount a suitable socket wrench on the tool
carrier. Connect the wrench to the pneumatic system. Insert the wrench with the socket on the element to be
unscrewed or screwed on. Gradually pull the tool trigger. After the work is fi nished, dismantle the pneumatic
system and carry out the tool maintenance.
Wrench settings
The wrench allows the carrier head (VI) and the handle (VII) to be rotated. allowing you to adjust the position
while working to make the grip as ergonomic as possible.
MAINTENANCE
Never use petrol, solvent, or any other fl ammable liquid to clean the tool. Vapours may ignite, causing the
explosion of the tool and serious injury.
The solvents used to clean the tool chuck and the body may soften the seals. Thoroughly dry the tool before
starting work.
If you notice any malfunction of the tool, immediately disconnect the tool from the pneumatic system.
All components of the pneumatic system shall be protected against dirt. Dirt entering the pneumatic system
can damage the tool and other components of the pneumatic system.
Tool maintenance before each use
Disconnect the tool from the pneumatic system.
Before each use, introduce a small amount of storage fl uid (e.g. WD-40) through the air inlet.
Connect the tool to the pneumatic system and run it for approx. 30 seconds. This will allow you to spread the
preservative fl uid through the inside of the tool and clean it.
Disconnect the tool from the compressed air system again.
Insert a small amount of SAE 10 lubricant into the tool via the air inlet opening and the openings designed for
that purpose. The use of SAE 10 lubricant is recommended for the maintenance of pneumatic tools. Connect
the tool and run it for a few seconds.
Caution! WD-40 cannot be used as a proper lubricating oil.
Wipe off any excess oil which may have escaped through the outlet openings. The oil left can damage the
tool seals.
Other maintenance activities
Before each use of the tool, make sure that there are no signs of damage to the tool. Keep drivers, tool chucks
and spindles clean.
Have the tool inspected by a qualifi ed workshop personnel every 6 months or after 100 operating hours. If the
tool has been used without the recommended air supply, increase the inspection intervals of the tool.
Removing defects
Stop using the tool as soon as you detect any defect. Use of a defective tool may result in injury. Any repairs or
replacements to the tool components must be carried out by qualifi ed personnel at an authorised repair shop.
