Action 11. Cleaning the filter of the cab
heating and ventilation system
• Lift the cab roof (1).
• Unscrew the two fastening bolts and
remove the filter cover (2) together
with two filtering elements (3).
• Slightly shake up the elements to re-
move free dust particles from the filter.
Be careful not to damage the filter.
• Clean the filters with compressed air
under the pressure of not more than 2
kgf/cm
2
pressure. Keep the hose injec-
tor at the distance of minimum 300 mm
from the filter so that not to damage
basis filtering element. Direct the air
flow through the filter against the nor-
mal air flow shown by the arrows on
the filter.
• Fit the filter by performing the actions
in the reverse order.
NOTE: Under humid conditions, e.g.
early morning, do not switch the fan on
before servicing the filter, since mois-
ture particles got into the filter are diffi-
cult to remove.
NOTE: When operating the tractor un-
der high dustiness conditions, clean the
filer at shorter intervals.
Action 12. Greasing the clutch shifter
bearing
Remove the plug (1) from the left side of
the clutch casing.
Insert the injector of the lever-plunger
pressure gun into the opening and make
4-6 injections of the grease “Litol-24”
through the oil feeder screwed into the
shifter body to lubricate the release
bearing.
NOTE: Do not inject excess grease,
since it will be accumulated inside the
clutch casing and can get on the friction
surfaces of the driven disk friction fac-
ings.
