3.10.1 - Air conditioning system
IMPORTANT: When the air conditioning system is in
use, the cab doors and windows should be closed. Do
not use the air conditioning system when the tempera-
ture falls below 20° C (68° F). Switch off the system
before starting up the engine. Ensure the cab air filter is
clean (see chapter 5).
NOTE: If the air conditioning has not been used for
some time, unlock the compressor before starting the
engine, by rotating the pulley nut with a wrench.
IMPORTANT: To prevent seizure of the compressor and
keep the cooling system in good condition, operate the
air conditioning for a few minutes at least once a week
even in winter.
ONCE A YEAR HAVE THE CIRCUIT CHECKED BY YOUR
DEALER.
WARNING: Do not attempt to disassemble
any part of the air conditioning system.

3.10.3.2 - General characteristics
The temperature inside the cab is controlled automatically
by the air conditioning system that controls the tempera-
ture at the air vents, the fan speed, recycling and the com-
pressor operation.
The required temperature can vary by 0.5°C (1°F) between
20-24°C (68-76°F) and by 1°C (2°F) outside this tempera-
ture range.
Scale of Celcius and Farenheit temperatures:
°C - LO/18/19/20/20.5/21/21.5/22/22.5/23 23.5/24/25/26/
27/28/HI
°F - LO/64/66/68/69/70/71/72/73/74/75/76/78/80/82/84/HI
