The next and final step for threading the upper twine depends on whether the bale channel
is empty or filled.
If bale channel is empty:
Knot the upper and lower twine in the middle of the bale chamber.
Or
Guide the upper twine under the crossbeam of the knotting table and knot it on the
crossbeam of the upper baling flap.
In order to tension the tensioning arm (11), pull back the upper twine in front of the twine
guide eye (8).
If the bale channel is filled:
Read the actual bale length on the terminal.
If the difference between actual bale length and target bale length is > 50 cm:
Let the loose twine end of the upper twine hang down approx. 50 cm in the bale channel.
The tensioning arm (11) is tensioned when the upper twine is caught in the crop while during
subsequent baling.
If the difference between actual bale length and target bale length is < 50 cm:
Guide the upper twine under the crossbeam of the knotter table and knot it on the
crossbeam of the upper baling flap.
In order to tension the tensioning arm (11), pull back the upper twine in front of the eye (10).
