4. Unlock the other side of the telescopic section using the
same procedure.
Once the pins are retracted, use your external means
(second crane, forklift, etc.) to retract that section and then
remove the bolts to pin that section in a retracted state. Move
to the next section to be retracted (as necessary).
Locking Telescopic Sections
1. Retract the telescopic section until the locking pin (1,
Figure 4-193) is in the middle of the opening.
2. Remove the screw from the bore hole (4).
The locking pin (1) is then pushed out of the opening due to
spring tension.
3. Install the grease fitting into the bore hole.
4. Retract the telescopic section until the recesses (2) have
been set down on the telescopic section (3) above it.

CAUTION
Risk of damage in the event of a mechanically
released lock!
Under no circumstances may you operate the telescoping
cylinder as long as the lock is mechanically released.
Therefore unscrew all screws out of the bore holes
immediately after finishing the repair work.
In this way, you prevent the telescoping cylinder from
hitting the locking system and consequently damaging it.
Do not unlock a section and then boom up until it slides in.
Damage to equipment will result.
WARNING
Never leave the crane with a load suspended. Should it
become necessary to leave the crane, lower the load to
the ground and stop the engine before leaving the
operator’s station.
