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 further than with a return run.
The following table shows the extended length for locking and unlocking
the telescopic sections.
