3.4.2 FEELER ADJUSTMENT
The feeler adjustment lever (Fig. 11) is positioned on the left side
of the machine and works according to a graduated scale that runs
from 0 - 9 settings. The lever must be set to the number indicated
by the sowing table on the basis of the type of seed to be sown.
If the feelers (B Fig. 12) are correctly positioned, they assure a
fl uid and constant distribution of the seeds.
ATTENTION
The lever positioned beyond the maximum opening, causes
the discharge of the seeds from the hopper.
For best seeding results, periodically check the position of the feeler
pins (B): the lever (Fig. 11) in position "0", adjust the distance
between the feeler and the distributor roller (A) by means of the
nut (D) to 0,5 ÷ 1 mm (Fig. 12).
3.4.3 DISTRIBOTOR ROLLER ADJUSTMENT
The most appropriate type of seed distributor roller must be selected
prior to sowing on the basis of the type of seed being drilled (A
Fig. 12). The machine is fi tted with rollers for small, medium and
large seeds. Select the type of distributing roller according to the
information given in Table 3 (page 46). Which is selected by in-
serting the key supplied (Fig. 13) into the slot on the left side of the
roller and push the drag retainer all the way out. Perform the a.m.
operation in inverse order to retum the roller to its initial position.
3.4.4 BLADE ADJUSTMENT
The sliding doors (C Fig. 12) for the discharging of the seeds from
the hopper, have three adjustment positions (Fig. 14):
1) Position 0: when the blade is completely lowered it closes the
seed discharge slot completely and shuts out the distributor
roller to which seeds no longer fl ow.
2) Position 1: by raising the sliding doors to the fi rst setting,
the medium aperture position indicated in the enclosed table
forsmall seeds is obtained because the discharge slot comes
to be only partially opened.
3) Position 2: this is the position of maximum aperture that is
indicated for medium and large-sized seeds.
