1. Insert the number of the read off scale lines for the individual
fertiliser levels (I, II, III, IV) into the relevant (I, II, III, IV) in the
upper line (Fig. 8/1) of the calculation scheme to determine the
spreading vane setting positions.
2. Calculate the values A, B, C, D, E, F and G according to the
prescribed procedure in the relevant calculation scheme one by
one.
3. Add the values "F" and "E" to calculate the spreading vane set-
ting positions for the short spreading vane.
4. Add the values "G" and "E" to calculate the spreading vane set-
ting positions for the long spreading vane.
5. Correction of the spreading vane positions by the calculated
spreading vane adjusting positions.
5.1 Negative value: Swivel backwards the vanes by the value
on the scale.
5.2 Positive value: Swivel forward the vanes by the value on
the scale.
6. Repeat the working width check with the new spreading vane
setting positions.
