5.1.2.5. QUICK UP/QUICK DOWN (optional)
This lever controls the quick lifting/lowering of the platform, while simultaneously controlling the following manoeuvres:
▪ Pantograph lifting/lowering
▪ Upper boom lifting/lowering
▪ Jib lifting/lowering
▪ Telescopic boom extension/retraction
To carry out the QUICK UP/QUICK DOWN manoeuvre, use the proportional lever F.
Set the proportional lever F forward for quick lifting or backward for lowering.
5.1.2.6. Turret orientation (rotation)
To carry out the turret orientation (rotation), use the proportional lever G.
Set the proportional lever G to the right for right rotation or to the left for left rotation.
Before carrying out this manoeuvre make sure that the mechanical lock device of the turret - if any - be
deactivated (see chapter 6 “Handling and carrying”).
With platform lowered (booms down, telescopic boom in, jib at a height between +10° and –70°) simultaneous
steering-drive-turret rotation is possible to facilitate the machine positioning in narrow spaces.
5.1.2.7. Jib rotation (optional)
To rotate the jib, use the proportional lever H.
Set the proportional lever H to the right for right rotation or to the left for left rotation.
5.1.2.8. Platform rotation
To rotate the platform, use the switch l.
Set the switch I to the right for right rotation, or to the left for left rotation.
5.1.2.9. Platform levelling
The platform is automatically levelled. Should it be necessary to reset the correct level, use switch L.
Set switch L to the left for backward levelling, or to the right for forward levelling.
Warning!! This operation can be carried out only when booms are completely lowered. No result is achieved if
these operations are carried out when the platform is lifted.
This manoeuvre cannot be carried out when other operations are taking place.
