5.1.1.3. Widening or narrowing the tracks (optional)
Once the operations in paragraph 5.1.1 have been carried out, to
achieve Widening or narrowing movement of the roadway, perform
the following operations in sequence:
Press “dead-man” button A on the control panel. The green led ZB
will light up steady;
Within 2 seconds act on the switch U in position:
- 1 - To reduce the track width by retracting the outriggers;
- 2 - To increase the track width by retracting the outriggers.
It is necessary to keep enabled switch
U until the tracks are at their
mechanical stop (completely extracted or fully retracted).
If the movement is stopped, you can resume it by repeating the
sequence described above within 10 seconds.

WARNING!!
The operator on the cage is not allowed to carry out widening or narrowing operations of the tracks. For these
operations the operator has to get on the ground and control the machine at a safety distance.
The widening and narrowing operations of the tracks is active only if:
- The machine is in a stationary position (no other controls are under way);
- The green warning light ZC is lit (the turret is in the central position);
- The boom is fully lowered.
- The machine is placed on a flat surface resting on the tracks, or resting on the outriggers (there is no
inclination alarm - see light ZE).
WARNING!!
A spirit level on the boom or on the chassis allows the operator to control the machine levelling while
stabilizing. However, the machine is equipped with a chassis inclination control system disabling lifting
operations in case of unstable positioning. Work is possible only after placing the machine in a steady
position. If the audible alarm and red warning light ZE on the control panel turn on, the machine is not
correctly positioned; stabilization is necessary to operate the machine again.
With a second boom not completely resting on the fixed structure, the outriggers and tracks control is
inhibited.
An automatic system checks the position of the rotating turret. When green warning light ZC is lit steady, the
turret is correctly positioned and the widening and narrowing operations of the tracks is allowed. If the green
light ZC turns off, the turret position is not correct and the control is inhibited.
