5.1.2.4. Telescopic boom extension/retraction
To extend/retract the telescopic boom, use the proportional lever
E .
Set the proportional lever E forward for extension or backward for retraction.
On machines with simultaneous controls (OPTIONAL) this movement cannot be executed together with
the turret orientation.
5.1.2.5. 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”).
On machines with simultaneous movements (OPTIONAL) this movement cannot be executed together
with the telescopic boom extraction/retraction.
In standard machines the drive and steering controls can be executed simultaneously but they are
interlocked with the platform movement controls (lifting/lowering/rotations) except four wheel drive Diesel
machines (D-4WD) where with platform lowered (booms down, telescopic boom retracted, jib at height
from +10° to – 70°) only simultaneous drive-steering- turret orientation is allowed to help machine
positioning in narrow places.
In machines with simultaneous controls (OPTIONAL) the drive and steering controls can be executed
simultaneously but they are interlocked with the platform movement controls (lifting/lowering/rotations)
as previously; on the other hand the simultaneous drive-steering-orientation with platform lowered
(booms down, telescopic boom retracted, jib at a height from +10° and -70°) is allowed in all three
versions (electric “E”, electro - diesel “ED” and four wheel drive diesel RTD).
5.1.2.6. 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.
5.1.2.7. 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.
Both on standard machines and machines with simultaneous controls (OPTIONAL), this operation cannot
be executed together with any other ones.
