• go to the platform board in the centre of the working platform, check the voltage LED is on (pos. 2 fig. 4.3.3)
• check that the outriggers LED is off: If this is not the case, it means that there is a malfunction in the stabilisers end runs (pos. 4 fig. 4.3.3).
Stabilise the machine correctly, proceeding as follows:
• make the outriggers descend by alternately activating the levers (pos. 1-2-3-4 fig. 4.3.4)
• moving the levers downwards extracts the stabilisers, moving the levers upwards retracts them
• fully extract the stabilisers to lift the tracks
• observe the spirit level (pos. 5 fig. 4.3.4) situated at the side of the stabilisers controls and correctly level the platform, by appropriately activating the stabilisers levers: the machine is levelled correctly when the air bubble inside the indicator, is positioned in the central section (0°)
• check that the LED has switched on (pos. 4 fig. 4.3.3) that indicate the consent for boom ascent.
