5.1.1.2. Stabilization
Once the operations in paragraph 5.1.1 have been carried out, to
achieve the stabilization movement, 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 operate proportional levers I, L, M, N to control
the outriggers individually or use switch D (optional) for automatic
stabilization.

WARNING!!
The operator on the cage is not allowed to carry out translation and stabilization operations. For these
operations the operator has to get on the ground and control the machine at a safety distance.
Always check the firmness of the ground before lifting the platform. Place strong wooden boards under the
outriggers pads so as to spread the load on a wider surface.
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.
While using the outriggers, an automatic system stops platform lifting in the event that one of the pads does
not rest perfectly on the ground. The levelling outrigger pads are resting on the ground when all warning
lights ZA are ON.
When the platform is lifted if one of the feet looses contact with the ground, the corresponding warning light
ZA turns off, danger red light ZE turns on and all lifting movements are inhibited. Cage lowering on the ground
is still possible (lowering and turret rotation in both directions) at automatically reduced speed.
Specially provided microswitches located on the levelling outriggers control their position. With one or more
pads resting on the ground (one or more ZA warning lights are ON) drive is inhibited. To carry out drive
movement,it is necessary to lift the pads from the ground. When warning lights ZA turn off, pads are lifted.
To avoid improper use, a special microswitch checks the position of the lifting boom. 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 stabilization control is allowed. If the green light ZC turns off, the turret
position is not correct and stabilization is inhibited.
