2.5.9 LOCKING PIN SCREWS AND NUTS
All the pins used in the platform have been treated against wear and are provided with wel‑
ded flanges (1) to prevent them from rotating inside their seat.
Some pins are provided with rotation locking screws (2) while others are provided with a
retaining block that is welded on the machine body (3).
The pins located in the most delicate positions have threaded ends and are provided with
self‑locking nuts (4) or self‑locking threaded ring nuts (4) to prevent the structure from colla‑
psing.
The correct tightening of all the pin locking devices must be checked carefully and regularly,
according to the intervals indicated by the machine manufacturer.
Never loosen the pin blocks and check regularly their proper tightening. Even If a pin comes
partially out of its seat, this could cause sudden and uncontrollable movements and also the
lost of stability of the machine and/or the falling of the control car.
2.5.10 FOOTSWITCH
To allow the aerial, undercarriage and stabilization movement
of the machine the footswitch device inside the basket must be
pushed.
2.6 EMERGENCY DEVICES
The emergency instructions reported below regarding the emergency devices are supplied to
the user so that they can understand the behaviour of the machine and the possible working
sequences; it will also be easier to identify them clearer and thus act quickly in case of emer‑
gency.
Before starting any operations, it is important that the operator checks the perfect working
order of the emergency devices.
