6.0 MAINTENANCE AND FAULTS
Activities for specialised maintenance technicians
Specialised maintenance technicians must know all of the procedures and correct methods for operating on the equipment (the Safety Manager
must ensure that the person is suitable and has all of the necessary requisites to carry out the work). The following operations are purely
indicative and of a general nature. Each piece of equipment must be assessed within the context of the system in which it is inserted, for the
duration of its use and for the environmental conditions in which it operates.
The Manufacturer is limited to indicating the operations to be carried out and the recommended frequency. Specialised maintenance technicians
must have the necessary skills to work in conditions of maximum safety.
