b)
On the valve-block on the undercarriage,
singularly
move the levers that control the arms,
until the operator is on the ground.
NOTE: in the model 1470, when you are using the emergency descend, the jib cylinder cannot be
activated, then when the arm is completely down, the basket is at about 1,8 m height. In this case, in
order to help the operator, you have to use an external tool (for example a ladder).
2.4.3 Emergency descend from the ground through the manual pump in case of failure of all the
systems conveying energy.
This emergency descend is to be used only in case of:
-
failure of the electric system of the machine, when it is not possible to make any emergency
manoeuvres from the basket;
The only reason to allow the use of the emergency descend from the ground is to compensate a
failure in the system and bring back the basket on the ground; any other use is forbidden.
The emergency descend from the ground can be made using the hydraulic manual pump.
