2. Adjust the tension of the chain if necessary.
a. The tension can be adjusted with the two tension nuts mounted on each
side of the elevator housing.
b. Adjust the nuts (A) on each side of the elevator housing to the same
tension.
The tension of the chain must not be too tight.

2. When the soil is poorly distributed:
a. Loosen soil directing plate (A).
b. Move the soil directing plate forwards or backwards.
