CLEANING OF HEATING SYSTEM
FILTERS
Carry out regeneration of filters, installed
under covering grilles above front glass
outside the cabin, as necessary accord-
ing to the degree of clogging:

by dusting,

by purging using compressed air.
Carry out checks of clogging every day.
Replace strongly clogged filters.
The safety cabin of the tractor is
not equipped with any special fil-
ters of air sucked into the cabin.
The filters do not protect the
driver against effects of aerosols
and other harmful substances!
*AIR FILTER WITH ACTIVE CARBON
Filters with active carbon are installed instead of the standard dust filter and re-
placement is carried out in the same way as in the common filters. The filter should
be located with the white surface on the grid.
The filter is used only when spraying pesticides, after the work the paper filter should
be reinstalled, because the carbon filter would be choked with dust after a short pe-
riod of time. Upon work the re-circulation controller should be in the position “air is
drawn into from the outside”.
The fan controller should be in the position “fan maximum work”.

WARNING: The filter does not provide full protection against toxic
substances.

When handling the filter, wear protective gloves.

Don’t clean the filter; don’t flush it with compressed air.
DANGER: The filter with active carbon should be replaced after every 200
hours or 36 months (manufacture date is stated on the filter). If you can smell
pesticides in the cabin, replace the filter immediately and check the cabin
sealing. Used filters should be disposed in special disposal centres.
