6.5.4 E
MERGENCY DESCENT CONTROLLED FROM THE GROUND IN THE EVENT OF SUDDEN OPERATOR
ILLNESS
,
WITH THE MOTOR RUNNING AND ELECTRICAL SYSTEM FAULT
This emergency descent function is used only if the operator feels ill while the motor is run‑
ning and the electrical system has broken down or if it is not possible to perform the pre‑
vious emergency operations.
Any movement of the arms must be performed AT THE MINIMUM SPEED POSSIBLE.
‑ Remove the cap from the solenoid valve (the external lead seal
breaks automatically when the cap is unscrewed and removed)
and close it manually by pressing and turning the underlying
knob: the internal wire sealed with lead breaks automatically and
closes the solenoid valve.
‑ Enable the aerial part by screwing completely the special flywheel
(see photo), located under the distributor protection casing on the
carriage.
‑ Act on the switch thus enabling the emergency distributor from
the ground.
‑ Use the distributor levers to enable the desired movement fol‑
lowing the instructions to be found on the label attached near the
controls.
The sequence of movements is the following:
‑ retract extension arm
‑ fold jib arm
‑ fold first‑second arm
‑ fold third arm.
The sole purpose of the emergency descent from the ground is to bring the basket to the
ground in order to assist the operator, all other uses are prohibited.
During this procedure it is prohibited to perform any operations other than those described
above, for example to extend the telescopic arm or the jib arm, to move the stabilisers and
generally to perform operations that may cause the machine to lose stability.
