Unlocking the Telescopic Section
Refer to Figure 3-169.
Move the right control lever for telescoping.
• If necessary, the telescope cylinder locking pins (3) will
extend first.
• The section locking pins will (2) retract:
Yellow: Intermediate position,
Red: Unlocked.
In the unlocked position, the symbol (1) is yellow.
If the control lever is moved, the telescopic section is
telescoped immediately.
If the symbol (1) (Figure 3-170) is still flashing after
approximately 10 seconds, this means that the section
locking pins are under load.
Let go of the control lever.
To relieve the load, carefully retract and extend the boom a
little.
NOTE: If removing the load does not cause unlocking, you
must lock the telescopic section again and restart
the unlocking process, refer to Lock Telescope
Cylinder, page 3-142.
CAUTION
Boom Damage Hazard!
Repeated attempts to extend and retract may cause
damage to the boom system.
