GUARDS AND DRIVER’S SEAT
3.5.4 VENTILATION AND HEATING
3.5.5 SEAT
The ventilation and heating of the cab serve to reduce the oper-
ator’s stress either in the summer and in the winter; these func-
tions also serve to eliminate the condensate from the front
window, thus ensuring visibility during both work and travel.
Ventilation and air change are achieved by means of a 2-speed
fan assembled inside the cab, under the right control case.
Air distribution is achieved by means of a fixed revolving outlet
(1) with adjustable capacity, installed in front of the fan.
A radiator having the function to heat the air conveyed into the
cab is installed beside the fan; it is used in the cold season and
receives the hot water necessary for the heat exchange directly
from the engine cooling circuit.
The water supply flow is divided or excluded by means of a tap
(2) positioned inside the engine compartment, on the left side.

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.
To reach the inside of the seat support, operate the lever (2) and
rotate the seat forward until engaging it with the safety coupling.
Use the lever (3) to release the safety device and bring the seat
to the correct position.
