JLG X17J Operator Manual - Manual (Page 100)

To perform the emergency descent in the conditions described
above, proceed as follows:
‑ 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.
‑ move the deviator located on the hand pump to the position corre‑
sponding to movement of the aerial part;
‑ Act on the switch thus enabling the emergency distributor from the
ground.
‑ Act on the distributor levers to enable the desired movement fol‑
lowing the instructions to be found on the label attached near the
controls and at the same time use the hand pump to power the
movement.
The sequence of movements is the following:
‑ retract extension arm
‑ fold jib arm
‑ fold first‑second arm
‑ fold third arm.
‑ Once the emergency operation has been completed, return the knob to its original posi‑
tion, taking care to put back the protection cap and have the double lead‑sealing resto‑
red by JLG qualified personnel.
Unscrew completely the flywheel that enables the aerial part.
