6. Maintenance section
6.1. General information
Attention
The product present in the tank or internally to
the machine must NEVER come into contact
with water or other liquids: this may lead to
the formation of moulds and bacterial loads.
Attention
If a bacterial presence is found on the product
derived from the processing carried out with
this machine model it will be necessary to
stop production immediately and contact the
manufacturer for the disinfection procedures.
Before carrying out maintenance or cleaning
procedures on the machine, cover the tank with the
supplied lid.
Never clean or lubricate components in motion.
Warning
Extraordinary maintenance on the machine is
exclusively carried out by the technicians
approved by the manufacturer.
The training course carried out only gives the
client the base instructions for ordinary
maintenance. The manufacturer suggests
carrying out a full service every two years to
guarantee the safety conditions.
Note
The maintenance technician must note on an
appropriate logbook all the interventions
carried out on the machine.
This section describes the ordinary checking
and maintenance procedures needed to
guarantee the correct functioning of the
machine.
Any other intervention that may be necessary to
eliminate anomalies or faults must be expressly
authorized by the manufacturer.
For major repairs it is recommended to turn to the
manufacturer
whose specialized personnel,
possessing the technical expertise acquired from the
original manufacturing in the factory, are always
reachable and able to intervene quickly.
For maintenance or replacement of commercial
components installed on the machine keep to the
instructions provided directly by the manufacturers.
Such instructions are normally attached to the
components or obtainable via catalogues or
manuals provided by the manufacturers.
Environment
The components replaced during maintenance
operations must be disposed of according to
the laws in force concerning waste materials.
If necessary, they can be sent to the
manufacturer, who will dispose of them in the
most appropriate manner.

shoes, etc.).
5) Make sure that the maintenance technician
has carefully read the instructions contained
in this manual and has excellent knowledge
