6.4.6 Setting of the feeding apparatus

The feeding amount can be increased or decreased by controlling the
frequency converter of the gear motor. If you wish to find out the exact
circulation speed, the easiest way to do this is to empty the unit with the
feeding apparatus and measuring the time.

6.4.7 Setting of the pre-cleaner aspirator

The aspirator setting should be carried out while monitoring the cleaning result. The flap is opened
when you hear the sound of grain rustling in the pre-cleaner. The flap is moved slightly towards
closed position and left in that position. The cleaning result needs to be checked in order to
minimise the quantity of kernels in the debris.
Adjustment of the levelling plate of the pre-cleaner.
The function of the levelling plate is to spread the grain as widely as possible to the intake of the
pre-cleaner in order for the pre-cleaning to be as efficient as possible. If the levelling plate is
adjusted correctly, it swings slightly during the filling and drying process. If the levelling plate is
too heavy, the pre-cleaner can get clogged. If the levelling plate, on the other hand, is too light, it
does not level the grain reducing cleaning efficiency.
