H. Periodic maintenance
and Adjustments” on page 85).
H 6.8. Change air filter and safety
filter (32)
69---82
The main air filter has to be changed no later than 1000
hours together with the safety filter if it has not been
cleaned already 5 times and changed earlier. The safety
filter protects the engine if the main filter should become
damaged. The safety filter must not be cleaned, it should
always be changed.
CAUTION: Never run the tractor without the safety
filter.
Take great care when removing the safety filter so that no
dirt enters the inlet pipe.
--- Take out the main filter
--- Remove the safety filter

Filters fitting
--- Check that, the seals are in good condition
--- Check that, the sealing surfaces are clean
--- Fit a new safety filter and make sure that it is correctly
positioned in the housing. Tighten the nut (1) carefully.
--- Fit the main filter carefully. Tighten the nut (2), on the
filter until the filter has come into contact with the end of
the housing.
Do not tighten the nut (3) on the cover of the air cleaner
housing too tight (approx 1---1.5 turns after the flange seal
has come into contact with the surface of the housing).
The cover of the housing (also in cyclone cleaner models)
must be mounted so that the outlet pipe (4) is in the lower
position.
H 6.9. Lubricate front wheel bearings (33)
(2WD)
3565---117,1
Use Valtra Universal Grease.
In dusty and muddy conditions, it is necessary for
lubrication to be carried out much more often. When
injecting new greese, ensure that enough is injected so
that it pushes the dirt out of the hub.
Check also the bearings tightness and if necessary have
them adjusted at an authorized workshop.
