Ø
Whenever performing assembly work on the motor mount it with the bore fa-
cing down to prevent water from entering the housing.
Towards the bottom the metering unit is completed by the fall sluice. In the fall
sluice the seed is picked up by the air flow.
During calibration the seed is taken out of the metering unit through the opening in
the fall sluice.
The covering must subsequently be closed again tightly.
10.1 Rotors
A large number of rotors is available for the different seed types with numerous
geometrical shapes and grain sizes, as well as fertilisers in form of powders or gran-
ulates.
There are also rotors with special properties available for fertiliser, fine and coarse
seeds.
