Personnel
The work for rectification of faults described here can be carried
out by the operator, unless marked otherwise.
Some works must be carried out only by specially trained skilled
personnel or exclusively by the manufacturer. Information on
this can be found in the description of the individual faults.
Work on the electrical system must, in principle, be carried out
only by electricians.
