Remove the circlip and plain washer.
Pull out the drive shaft and insert it into the
new roller.
Axial play of the drive shaft in the roller is neces-
sary for self-cleaning the roller when installed in
the metering unit housing.
The base of the metering unit is shut off from
the Venturi pipe. In the Venturi pipe, the seed

When calibrating, the seed is removed from

The cover must then be firmly closed and sealed
once again.
