Figure 5. Feed adjustment hand-wheel
The hand-wheel is locked with a plastic lever on which is also marked the main feed
scale, 0-10. The interval between numbers equals a single rotation of the hand-wheel.
The outside of the hand-wheel is marked with 10 locking doors, labeled 0-9. Using
these allows 100 different adjustment positions to be generated. With small seed
transmission (pin position II, see Fig. 7) 100 feeding adjustment positions can be
generated in the same way from the smaller rotation number area. The main scale
value is read from the inner edge of the hand-wheel.
Rotating the hand-wheel counter-clockwise increases the feed. When the desired seed
sowing amount is known from the sowing chart located inside the machine cover (or
from this manual, see Fig. 10), the instructed feeding adjustment position can then be
seen. Note the right position of the pin in shafts, see Figs. 6 and 7.
The hand-wheel should always be adjusted so that the desired adjustment position is
always approached from a greater adjustment position. If the original adjustment
position is smaller than desired, the hand-wheel should be rotated counter-clockwise
1/2-1 times beyond the intended adjustment, and then rotated backwards to the desired
adjustment position.
After this, the adjustment locking lever is inserted into a notch on the hand-wheel, which
then locks both the wheel and lever.
Note that the adjustment position given in the sowing chart is for reference only - the
actual feed amount will change between different seed batches. In order to determine
actual feed amounts and obtain an objective value, you should always perform a
calibration or field test, see Section 4.4 below.
