Recirculated air/fresh air (A)
MIN = 100% recirculated air - 0% fresh air.
MAX = 0% recirculated air - 100% fresh air.
N = Normal setting approx. 80% recircu-
lated air - 20% fresh air.

Blower (B)
MIN = Minimum blower output.
MAX = Maximum blower output.
0 = Fan off.
Depending on the selector position, the blower
output can be increased steplessly.
CAUTION:
When using the tractor for spraying
operations (e.g. weed or pest
control), fit filter cartridge
(aerosols). Use only fan speed 1.
After each spraying operation,
replace the filter cartridge with a
normal cartridge. Follow the
instructions given with the filter. Cab

The air flow is controlled by and directed through
nozzles (in cab roof cladding).
MIN = Minimum blower output, cooling
power.
MAX = Maximum blower output, cooling
power.
0 = Blower / air conditioning OFF.
Depending on the selector position, the blower
output and cooling power can be increased ste-
plessly.
NOTE:
For health reasons it is advisable not to allow
the air inside the cab to drop by more than ap-
prox. 5 - 8 °C below the outside temperature.
Do not expose yourself directly to cold
draughts - danger of catching cold! For
energy economy and greater efficiency, we
recommend using the recriculated air mode.
WARNING:
All repair and maintenance work
must be carried out by qualified
personnel only.
Avoid all contact with liquid coolant.
If accidentally splashed in the eyes,
seek medical advice immediately.
No welding should be carried out on
or near any parts of the air
conditioning systems! Risk of
poisoning!
Maximum ambient temperature for
coolant 80 °C.
Check the V-belt only while the
engine is stopped. Attach the
protective grille again.
