ARRANGEMENT FOR THE INSTALLATION OF THE CLAMSHELL BUCKET
6.9.1.2 VERSION WITH SERVO CONTROLS
(if installed)
If the machine is equipped with backhoe servo controls, the
swinging movements of the clamshell bucket are operated
through the push buttons (2) and (3) positioned on the left joy-
stick lever.
The movements of the main equipment (boom, arm and boom
swing) remain unchanged.
The circuit used for opening and folding the standard bucket is
used also for opening and closing the clamshell bucket, exclud-
ing the control cylinder.
See “3.3.5.2 MACHINE CONTROLS (Version with servo con-
trols)” pos. 15-16 and “6.9.2 INSTALLING THE CLAMSHELL
BUCKET”.
The swing movements of the bucket are controlled as follows:
1 - when the push button (2) is pressed, the bucket swings clock-
wise;
2 - when the push button (3) is pressed, the bucket swings anti-
clockwise.

All the movements of the boom, the arm and the equip-
ment are inhibited when the control safety device is

servo controls)” pos. 26.
