The following points are of particular importance:

servicing work is carried out. Measures to be taken to
ensure that the unit cannot be switched on accidentally!

to avoid risk of burns!

instructions to be strictly adhered to in this case!

pressure removed before dismounting pressurised parts.
Scrupulous standards of cleanliness to be maintained
during servicing work; parts and exposed openings to be
covered with a clean cloth, paper or masking tape.

etc. to be protected from ingress of moisture, e.g. when

close proximity to the oil system; oil tank to be fully
discharged and cleaned before such work.
No tools, loose parts or rags to be left in or on the unit.

equipment and cut-out devices to be checked for perfect
working order before unit is released for operation after
servicing work.
Doors on unit to be closed before switching on the unit
(including for test run)!
