Locking points for the telescopic sections
The telescopic section must not be set down for locking or unlocking it.
The cutout ( 1 ) must be clear. That is why you have to extend the telescoping
cylinder about 25 mm further than for a return run.
The following table shows the extended length for locking and unlocking
the telescopic sections.
