11.5.3.Emergency descent in the case where the stabilisers are accidentally re‐
tracted
While it is recommended to follow the instructions provided in the paragraph on
stabilising the machine, for various reasons one of the stabilisers may lose contact
with the ground, thus changing the angle of the machine or causing a foot plate
to lift from the ground. If this occurs when the machine is at a height, movements
are stopped and disabled immediately. To restore operation of the platform (close
the aerial part and then stabilise the machine again) the electrical emergency de‐
scent function can be used, which involves only the return of the aerial part. If this
is not possible due to the presence of objects that interfere with the operation, per‐
sonnel on the ground can allow the operator in the basket to close the machine.
The operators on the ground can bypass the machineʹs safety devices and allow
the operator in the basket to close the machine or allow the manual operations as
described in the previous paragraphs, in order to bring the operator back to the
ground.
Read the instructions provided below before performing the opera‐
tion as it is potentially dangerous for the operator in the basket.
Proceed as follows:
