One of conditions of proper protection against electric shock is that the machine’s electrical installations must be periodically
inspected by entities authorised thereto to. Pay special attention while you repair or adjust your machine, as most of its ele-

you operate or adjust it. In the event its pressure system is unsealed when in operation, you can undergo severe burns from
high-temperature steam. Persons who perform maintenance/ adjustments at this machine should hold relative permits and
logbooks that allow them to carry out maintenance/ adjustments on thermal pressure equipment (Group G2 energy licence)
and electrical equipment (Group G1 energy licence).
