In the Operating manual supplied, it is noted that special care must be taken when
telescoping in the emergency programe (1), as no automatic monitoring takes
place.
If you move the telescoping cylinder without a telescopic section (return run),
please also note all the information in these additional pages.
(A) – These specifications apply to the outermost
telescopic section (3) – on all fixed lengths.
•Always stop extending the telescopic cylin-
der (1) once the locking point (2) on the
outermost telescopic section (3) has been
reached.
There is no automatic shutdown.
(B) – If you move too far past the locking point (2),
the cylinder tube (4) will hit the main boom
head (5) at the front.
This can lead to damage which makes telescop-
ing the main boom no longer possible.
