Displayed emission values are comparative and are to be
employed for a provisional assessment of the operator's risk
exposure during the work period. Appropriate evaluation of work
period must also include tool's idle and stop periods. These
emission values represent the tool's main applications. If the
tool is used for other applications, with other accessories, or if
it does not undergo regular maintenance, emission values can
significantly increase during operations.

STARTING UP
Before starting-up the tool, ensure that:
- the packaging is complete and does not show signs of having
been damaged during storage or transport;
- the available compressed air production and distribution plant
is capable of satisfying the requirements reported on the tool's
identification plate.
ASSEMBLING THE TOOL
Assemble the compressed air connection (not supplied) by
screwing it into its seat (5).
Ensure that, when compressed air is connected, the
pneumatic tool activation switch (2) is disconnected.
For the compressed air supply a compressor complying with
the technical characteristics listed in the tool data label must be
used.
All instruments, connection hoses and pipes must be suitable for
the corresponding pressure and quantity of air necessary.
COMPRESSED AIR CONNECTION
(NOT SUPPLIED)
The tool is supplied without the compressed air connection;
the user can use either a quick release coupling or hose type
connection according to his needs, as long as they have an hole
of air passing mm. 8.
In the latter case the air line must be fixed to the nozzle by a
hose clip.
STARTING AND STOPPING
- Starting: push the control lever (2) forward towards the body of
the tool and keep it pressed;
- stopping: release the control lever.
