USE OF THE AIR CONDITIONING SYSTEM

To lower the temperature and, at the same time, the
humidity of the air inside the cab, turn knob (2, fig. 9)
counter--clockwise until the desired temperature is
obtained.
Warning -- Before starting the engine, check that the
air conditioning knob (2 fig. 9) is in the "off" position.

crease the pressure inside the cab to prevent dust
entering, it is advisable to close the recirculation
vents.

lowering the air temperature, turn knob (2, fig. 9)
clockwise to obtain the desired temperature.
After prolonged operation in hot sunshine, to bring
the air inside the cab back to the optimum tempera-
ture, without the tractor moving switch on the air con-
ditioner and open the rear window or hatch to dis-
charge the hot air.
SWITCHING OFF THE AIR CONDITIONING SYS-
TEM

conditioner by turning knob (2, fig. 9), then turn the
fan control knob (1, fig. 9) to the "off " position.
