Aerial manoeuvres enabling
Its function is to allow the aerial platform to be moved only when the machine has been stabilised.
There is a micro switch on the foot of each stabiliser, located below the stabiliser carter, that detects
if the stabiliser is resting on the ground. There are another two micro-switches on the vehicle’s rear
springs which detect minimum stabilisation. When the machine is being stabilised, indicator lights
1, 2, 3 and 4 next to the stabilisation controls will light up only when all the feet are resting on the
ground and the minimum stabilisation has been reached (see Fig. 4.3), and it will then be possible
to raise the boom.
