health, they must also be decontaminated.
For shipping, the parts must be packed in tear-
proof plastic bags of sufficient size in such a
manner that they are tightly sealed and leak-
proof. Furthermore, the packaging must protect
the lifting unit from damage during transporta-

In order to prevent damage or serious injury when
repairing malfunctions on the lifting unit, the
following points must always be observed:

are available for this work, i.e. the individual tasks
must be carried out by trained specialists. For
example, electrical work must be performed by an
electrician.
• Always secure the lifting unit to prevent it re-
starting inadvertently, by disconnecting it from
the electrical mains. Take appropriate precau -
tions.
