3.5.5 SEAT
3.5.5.1 SEAT (STANDARD)
The seat is really comfortable, in fact it features five different
adjustment options:
a - longitudinal position;
b - back inclination;
c - degree of suspension, in order to dampen the inevitable
vibrations and jumps as much as possible;
d - height and cushion inclination;
e - rotation for works with the backhoe.
The operator can choose the driving position that is most suit-
able for his physical structure and according to the angular ad-
justment of the steering wheel.
The longitudinal adjustment of the seat can be carried out by
means of the lever (1), making the seat slide on the apposite
guides; once the desired position has been found, release the
lever and make small movements with the seat to make sure
that the retainer pin is correctly engaged in its seat.
The back can be adjusted by operating the levers (2) and at
the same time exerting pressure with the back; the back will
automatically adapt to the physical structure of the operator.
The adjustment of the suspension is carried out with the snap
lever (3) and can be controlled by observing the position of the
indicator (4).
The operator must carry out this adjustment while seated; the
right suspension degree is reached when the indicator is posi-
tioned in correspondence with the seat frame.
If the indicator protrudes from the frame, it is necessary to op-
erate the lever (3) with the (+) mark on the grip towards the op-
erator; if the indicator is positioned inward with respect to the
frame, the lever (3) must be operated with the (–) mark on the
grip towards the operator.
The seat cushion inclination and height can be adjusted by
means of the lever (5); three height positions and five different
inclination options are available.
The rotation of the seat for works with the backhoe is obtained
by operating the release lever (6); the locking is automatically
carried out every 180°.
CAUTION
q
The seat is equipped with a safety system that sends
out an acoustic alarm if the reversing gear control lever
is operated while the seat isn’t in the correct frontal po-
sition.
