GETTING TO KNOW THE TRACTOR
E123 E124
FAST COOLING OF THE CABIN
SPACE
1. Turn the heating valve control (A) to
the left.
2. Set the air circulation in the cabin
control (D) to inner recirculation.
3. Select the desired speed of the fans
(position 1, 2, 3) using the fan control
(B).
4. Switch of the A/C system using the
button (C).
5. Adjust angles of the air outlets to pre-
vent direct blowing of persons in the
cabin (risk of an disease due to in-
tensive cooling of body parts).
OPERATION OF HEATING OF AIR-
CONDITIONING WITH WORK OF THE
TRACTOR
In case that inner recirculation is activa-
ted, fresh air supply is closed and all the
air in the cabin becomes breathed up.
This situation may cause a feeling of fa-
tigue.
Note: When working with the tractor, set
the control (D) to fit your individual requi-
rements for temperature, i.e. between
positions (a) and (b) so that the fan will
suck outdoor air through the filters.
When spraying pesticides and
using the heating filter with active
carbon, the re-circulation control-
ler should be in position “air is
drawn into from the outside” and
the fan controller should be in the
position “fan maximum work” to
create overpressure in the cabin.
