Ordinary and extraordinary maintenance must be carried out solely by the operator assigned to perform maintenance
(mechanical and electrical maintenance staff) according to the regulations in force in the country of use and respecting
the laws regarding systems and work safety. Remember that, by operator assigned to perform maintenance is meant
the person who can work on the machine to perform ordinary and extraordinary maintenance, repairs and fine tuning.
This person must be an expert operator, properly instructed and trained, given the risks involved in such operations.

ARNING
Before performing any ordinary and extraordinary maintenance, the machine must always be stopped (by disconnecting
from the mains) and the EMERGENCY button engaged. The switch must have a key that must be removed and held by
the operator who will perform the operations until the end of the maintenance itself.

It is absolutely prohibited to remove any protections from moving parts and unit protection devices with the machine
connected to the mains or operational. Adjustments made with safety devices disengaged must be performed by a sin-
gle person, expert and authorised, and during this activity it is necessary to prevent access to the area of the machine
by other people. Upon completing the adjustments with safety devices disengaged, the protections must be re-engaged
as soon as possible.
