Main oil filter and lubricating oil filter,
replacing
Replace the filters every 1000 hours in connection with
changing oil. The filters are of the disposable type, i.e. they
cannot be cleaned but must be replaced.
NOTE! Always replace both filters at the same time.
Removing
Let down the guard plates to access to the filters. The main oil filter
is located on the left side and the lubricating oil filter is on the right
side of the transmission.
1 Use a suitable tool to remove the filters.
Installing
2 Fill the filters with oil.
3 Coat the gasket with oil.
4 Then screw on the filters until the gasket just touches the
sealing surface.
5 Then tighten the filters a further ½ turn.
After installing

not, remove the filter and check the sealing surface.
NOTE! Usually it does not help to tighten harder.
