GUARDS AND DRIVER’S SEAT
3.5.6 SEAT
The seat is extremely comfortable, offering several adjustment
options:
a - longitudinal adjustment;
b - back inclination adjustment;
c - adjustment of the suspension, aimed at dampening the inev-
itable vibrations and jerks as much as possible;
d - seat cushion inclination adjustment;
e - headrest adjustment.
The seat is assembled on a unit that slides longitudinally and can
be moved forward or backward together with the control levers,
the dashboard and the cutout boxes. The operator can thus
choose the driving position that is most suitable for his physique.
The longitudinal adjustment of the seat is obtained by operating
the lever (1) and making the seat slide on the guides; once the
desired position has been found, release the lever and carry out
slight movements, in order to make sure that the lock pin is en-
gaged in its seat.
The back adjustment is achieved by operating the lever (2) while
pushing with the back; the back will automatically adapt itself to
the operator’s body.
The adjustment of the degree of damping is carried out with the
handwheel (3) and can be checked in the transparent band of the
handhweel; optimal adjustment is obtained when the weight indi-
cated in the handwheel corresponds to the operator’s weight.
The suspension can be stiffened or lightened according to the op-
erator’s needs; adjust the seat suspension by rotating the hand-
wheel (3) clockwise (+) to stiffen the suspension or anticlockwise
to lighten it.
The inclination of the seat cushion is obtained by operating the le-
ver (4) and positioning the front part of the cushion at the same
time; it is possible to select 4 different positions.
The headrest height can be adjusted and the whole headrest can
be inclined according to the needs of the operator.
The seat is fixed to the sliding control unit and the whole can be
shifted forward or backward for 80 mm and can be locked in 6 dif-
ferent positions.
The longitudinal shift of the whole control-seat unit is obtained by
operating the lever (5) and making the unit slide on the guides;
once the desired position has been found, release the lever and
carry out slight movements, in order to make sure that the lock pin
is engaged in its seat.
