Telescoping The position of the telescopic sections, i.e. which telescopic section is
extended to what extent, is referred to as telescoping.

sequence
The telescopic sections can only be telescoped individually, one after the
other.
When extending, the telescopic section (1) to (6) with the highest number
must always be extended first, then the telescopic section with the next
lower number and so on (e.g.
IV, III, II, I).
The telescopic sections are always retracted in the reverse order of
extending.
