14.5.2 Telescoping emergency program
In the event of a malfunction in the telescoping mechanism, you can retract
the main boom with the
Telescoping emergency program.
The emergency program is not intended for crane operation and is there-
fore restricted to a certain amount of time.

p. 14 - 47.
– When a swing-away lattice is folded to the side then you must perform the
steps in the following section before telescoping.
When the
Telescoping emergency program is switched on, the swing-away
lattice is not automatically pivoted before and after telescoping.
• Always check that all prerequisites are
fulfilled before telescoping via an
emergency program.
(A) – Telescoping position
When the swing-away lattice is in the tele-
scoping position, you can telescope the main
boom.
(B) – Rigging position
When the swing-away lattice is in the rigging
position then you must first pivot it into the tel-
escoping position (A) before telescoping.

Risk of accidents due to the swing-away lattice falling!
Before telescoping, always check the emergency programme to ensure that
the swing-away lattice is in the telescoping position.
This way you will prevent telescoping parts from colliding with the swing-
away lattice, brackets from coming off and the swing-away lattice from
falling down.
