Adjustment of aspiration cleaner
1. First close air slide (A) completely.
2. Adjust the guiding plates by means of the hand-
le (B), to ensure that the crop layer is equally
high in both sides of the cleaner. This may be
checked through the inspection windows on the
sides.
3. Adjust the spring loaded device (C) of the "grain
shutter" so that the shutter will not open until
there is grain throughout the width of the shutter.
4. Adjust the air slot in the aspiration cleaner using
the handle (D), to avoid extraction of too many
whole grains.
This may be checked as follows:
4.1 If there are many whole grains in the
screenings they will produce noise in fan
and pipeline.
4.2 Collect the screenings after the dust
cyclone and check that there are not too
many whole grains.
4.3 The screenings can also be inspected
through the window on the back of the
aspiration cleaner.
5. In handling light crops too many whole grains
may be extracted although the aspiration
cleaner is set to minimum extraction. In sush
cases open the air slide (A) a little.
