7.3 Unscheduled maintenance
CAUTION!
Unscheduled machine maintenance and repairs shall only be carried out by qualified, trained and authorised
technicians, employed by the Manufacturer or by the authorised service centre.
These interventions require thorough and specialised knowledge of the machine, of the operations required, of the
risks involved and of the correct procedures to work safely.
If exceptional events occur, which require unscheduled maintenance work to be carried out, the user’s routine maintenance
technicians must follow these procedures:
• check the condition of the damaged or out-of-phase units;
• perform the operations described in this section;
• if the operations to be carried out are not indicated in this manual, send the report of what occurred, the result of the inspection
and any observations to the Manufacturer.
The Manufacturer or the authorised service centre will evaluate the situation case by case. Then the type of work to be carried
out will be agreed with the routine maintenance technicians, and the most suitable solution will be chosen from the list below:
• the Manufacturer will send an authorised, trained and qualified technician to carry out the necessary work;
• or the Manufacturer will authorise the user’s routine maintenance technicians to carry out the work and send any
additional instructions.
CAUTION!
Replacement spare parts must be ordered from ARS S.r.l.
If the customer does not use spare parts that are original or authorised in writing by the Manufacturer, the latter
shall be deemed free from any liability concerning machine operation and operator safety. Authorisation and/or
instructions must always be provided in writing. In the absence of written authorisation, it is forbidden to operate
and the Manufacturer disclaims all liability.
CAUTION!
Maintenance operations must be carried out only by qualified and authorised personnel.
CAUTION!
Disconnect the power supply before taking the cover off.
CAUTION!
Disconnect the power and air supply before starting any maintenance operations.
