Oshkosh X17J, Operation Safety & Maintenance Manual

Page: 96 / 172

From this position the automatic device for preventing collisions between the first arm and
the engine cannot be activated, so be sure to avoid any contact between the two parts. Negli‑
gent use may cause serious damage to the structure and injury to operators both in the
basket and on the ground.
6.5.3 E
MERGENCY DESCENT IN THE CASE WHERE THE STABILISERS ARE ACCIDENTALLY RETRACTED
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 descent 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, person‑
nel on the ground can allow the operator in the basket to close the machine.
The operators on the ground can bypass the machine’s safety devices and allow the operator
in the basket to close the machine or allow the manual operations as described in the pre‑
vious paragraphs, in order to bring the operator back to the ground.
Read the instructions provided below before performing the operation as it is potentially
dangerous for the operator in the basket.
Proceed as follows:
‑ Open the electrical components compartment.
‑ Position the emergency key on the electrical components compartment, removing it from
the side where this is lead‑sealed (see photo).
