5.1.1.2.1. Manual stabilization control
To lift/lower the outriggers it is necessary to operate one or more of the four control levers I, L, M, N.
If you set levers I, L, M, N downwards, the levelling pads extract; vice versa, if you set the levers upwards, they retract.
The location of the control levers I, L, M, N and relevant warning lights ZA corresponds to the arrangement of the outriggers:

Lever N ; Warning light A = Front left outrigger;
 Lever I ; Warning light B = Front right outrigger;

Lever M ; Warning light C = Rear left outrigger;
 Lever L ; Warning light D = Rear right outrigger;
For a correct manual stabilization:
 control all the outriggers simultaneously until the support pads are close to the ground;
 set the support pads near the ground by controlling a pair of outriggers at a time until the tracks raise slightly from the
ground;

correct stabilization by controlling one or two outriggers at a time until the machine is levelled and displayed by the spirit
level.
5.1.1.2.2. Automatic stabilization control (OPTIONAL)
Alternatively, the machine can be supplied with an automatic stabilization system. The system has two operating modes:
 manual mode (see previous paragraph)
 automatic mode.
For AUTOMATIC STABILIZATION, set control lever D down. The control system will independently control the outriggers until the
machine is levelled.
Levelling is correct when:

all four warning lights ZA are on;

inclination alarm warning light ZE is off (if an alarm condition due to instability before the levelling control is present);

enabled control station green warning light ZB from steady to flashing.
For a quick automatic stabilization:

control all outriggers simultaneously with the manual controls (levers I, L, M, N ) until support pads are close to the ground;

activate automatic stabilization control lever D .
For AUTOMATIC RETRACTION of all pads, set the control lever D upwards. The control system will retract all pads up to the
upper stop.
During automatic levelling, the system aims to level the machine within an allowance of 0.4° both
longitudinally and transversally. The system continues the pad control until levelling within this tolerance is
reached. If the automatic system is unable to obtain levelling within the expected allowance, yet the four pads
are firmly resting on the ground and the machine is within the stability limits controlled by the inclinometer,
lifting can be still carried out.
Excessive longitudinal and/or transversal inclinations may prevent the automatic levelling from being
reached.
