*Air filter with active carbon
Air-conditioning maintenance
Filters with active carbon are installed instead of the
standard dust filter and they are replaced in the same way
as the normal filters. The filter must be inserted with the
white side towards the grill. The installation instructions
are found on the next page.
The filter is only used during spraying of pesticides; then it
must be replaced with a paper filter again as flying dust
would clog the carbon filter in a very short time.
During its use the recirculation control must be in the
position of 'air suctioned from the outside'.
The fan control must be in the 'maximum' position.
WARNING: The filter does not provide complete
protection from toxic substances
- When handling the filter wear protective gloves
- Do not clean or blow the filter with compressed air
DANGER: Replace the active carbon filter every
200 hours or 36 months (the production date is
printed on the filter). If you feel the smell of pesticides
in the cab, replace the filter immediately and have the
cab sealing checked. Used filters must be disposed of
in specialized collection centres.

The most important element of maintenance of
the air-conditioning system is cleaning the AC
condenser (it is installed in front of the engine cooler).
If the AC condenser is clogged, it does not only
reduce the cooling efficiency of the AC system but
also the efficiency of the engine cooling.
Remove the front side plate of the hood, release and slide
the cooler towards the side and clean the condenser with
pressurized air or pressurized water (against the driving
direction of the tractor). Then, slide the cooler back and fix
it properly. Be careful about the proper routing of hoses to
the oil cooler.
F_02_120
When the air-conditioning functions properly, water
condenses in the roof space of the cab and the
condensate is drained through hoses in the cab pillars and
runs out at the bottom side of the pillar. This is why you
must make sure that the condensate drain hoses will not
be blocked.
