Safety precautions for maintenance
Ordinary and extraordinary maintenance must be carried out solely by the operator assigned
to perform maintenance (mechanical and electrical maintenance sta) according to the
regulations in force in the country of use and complying with the laws regarding systems and
work safety. Remember that, by operator assigned to perform maintenance is meant the person
who can work on the unit to perform ordinary and extraordinary maintenance, repairs and ne
tuning. This person must be an expert operator, properly instructed and trained, given the risks
involved in such operations.
Before performing any ordinary and extraordinary maintenance, the unit 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 unit connected to the mains or operational. Adjustments made
with safety devices disengaged must be performed by a single person, expert and authorised,
and during this activity it is necessary to prevent access to the area of the unit by other people.
Upon completing the adjustments with safety devices disengaged, the protections must be re-
engaged as soon as possible.
During maintenance the operational space surrounding the unit must be free of obstacles, clean
and well lit. It is prohibited for unqualied people to pass through or remain in this space.
Use personal protective clothing (safety shoes, safety glasses, gloves, etc.) compliant with regulations.
Before carrying out repairs or other work on the unit, always declare out loud your intentions
to other operators who are located in the unit area and make sure that they have heard and
understood the warning.
