GRT9165 OPERATOR MANUAL OPERATING PROCEDURES
Each telescopic section is equipped with two section locking
pins (7) which are extended by spring force.
The section locking pins (7) are pushed into the cutouts (4) of
the telescopic section at the locking points – the telescopic
section is locked.
The telescoping cylinder is attached to the base section (9)
with the piston rod (8). The telescoping cylinder has two
cylinder locking pins (5) at the bottom and a mechanism at
the top (10).
When the telescoping cylinder is positioned at a locking
point:
• The locking pins (5) can be extended into the cutouts (6)
– the telescoping cylinder is locked.
• The mechanism (10) engages into the locking pins (7)
and can retract them – the telescopic section is
unlocked.
Telescoping Process
The state shown in Figure 4-10 should be the starting point
for a telescoping process. The telescoping processes
consist of 4 steps:
1. Unlocking the telescoping cylinder
The locking pins (5, Figure 4-10) retract – the
telescoping cylinder is unlocked.
