FIG. 9. Feeder adjustment with handwheel. FIG.10. Hand wheel for adjustment.
The feed rate adjustment takes place by adjusting the feed roller laterally in relation to the plenum
chamber. Adjustments are made by the hand wheel at the left end of the machine (Fig. 10). The
handwheel is locked with plastic lever, in which is disposed the feed main scale of 0-10, where
the numbers correspond to one hand wheel turn. Adjustment is read from the inner surface of
the handwheel. A handwheel has for each revolution 10 locking position, marked 0-9. This gives
a total of 100 different control positions. With the small seed exchange (cassette position II) can
be respectively gained 100 output control positions of a smaller field.
NOTE:
To adjust the feed, the plastic latch must be pressed towards the end wall of the machine
to the arrow direction and at the same time rotated 90 degrees, resulting in the release of the
handwheel.
Rotating the handwheel counter-clockwise will increase the feed. When the desired amount of
seed sown is known, inside the cover a Sowing Chart will give an indicative output position of the
control.
Please notice the position of the cartridge. Adjustment should be made in such a way that the
adjustable target position is always approached from the larger adjustment position. If the initial
setting position is less than desired, the handwheel is turned anti-clockwise 1/2-1 turns over the
intended adjustment, after which the wheel is rotated back toward the desired control position.
After the adjustment, the lock lever arm is turned into the gap, the wheel and the lever will lock
into place. It should be noted that the adjusting position given by sowing table is indicative and
the actual feed rate varies between different seed lots. It is recommended that the feed rate is
verified by calibration test.
If the feeder accumulates dirt, the feed rollers may become clogged. This can contribute
significantly to the feed rate. We recommend cleaning it from time to time. The rollers can be
cleaned by adjusting the feed rate to zero and then back to the desired adjustment value. In this
case must be kept in mind the above-mentioned adjustment instruction, first turn 1/2-1 above the
desired adjustment value.
