instructions and warnings on the following pages.
Periodic maintenance and correct use are essential factors to guarantee the full efficiency and safety of the
machine.
The maintenance interventions and the prescribed operations help prevent problems due to deterioration of
the safety measures or resulting from machine downtime.
This way information on any extraordinary operations that may be necessary can be provided.
DANGER: The following operations must out be carried only by qualified and specifically trained
technicians. The Manufacturer declines all responsibility for operations carried out without respecting
the safety regulations, by unqualified operators and without compliance with the specifications of this
manual.
DANGER: Before carrying out any maintenance or cleaning operations described in this paragraph, it is
necessary to section the PARTLY-COMPLETED MACHINE from the electric power supply by acting on the
general disconnecting switch located on the panel that closes the electrical equipment. The
disconnector must be locked in the open position with a padlock.

During the interventions only authorised personnel may access the work area.
x
Disassemble only the parts of the machine that are actually required to perform the specific
maintenance operation.
x
Moreover, before returning the machine to the operators, it is necessary to verify its integrity and
functionality.
x
Operate, as far as possible, on the partly-completed machine and on the pipes only after
having emptied them and before proceeding with restart, ensure thorough cleaning of the
system.
