It consists of an electrical panel in which there are:
• the SK key: through it, it is possible to turn on
the electric system and start the endothermic

• the red light 3 which monitors coolant lev-
el;

bles the basket control station, at right the ra-

• the platform consent light 7: if lighted on, it
allows the maneuvers of the aerial part only
with stabilization correctly performed.
• the stabilization consent light 8: if lighted
on, it allows the movement of the outriggers

locked by turning it clockwise to reacti-
vate the normal machine working.
