for safety reasons, all the maintenance operations reported in this chapter must only be conducted by
qualified technicians that are specifically trained.
The responsible technicians must also have all the tools and IDP necessary to operate safely.
to always guarantee operators full efficiency and safety of the machine and prevent problems linked to
deterioration of the safety measures or machine stoppages which can be taxing, it is necessary to
implement efficient preventive maintenance, by planning interventions with planned intervals, with the
purpose of renewing or replacing the normal wear parts and audit the general status of the mechanical
and electrical components composing the machine (and its auxiliary equipment), thereby providing the
instructions on possible extraordinary operations which may become necessary.
the manufacturer declines all responsibility for any damage to property and/or persons deriving from
improper interventions conducted by unqualified, untrained, inadequately equipped or unauthorised staff.
