Threshing concave
Basic concave setting
NOTE!
When engaging the threshing mechanism after
an extended standstill period, the electronic unit
moves the concave to the closest and the
widest position.
After this, it moves the concave back to the pre-
selected position.
1. Bleeding the hydraulic cylinder:
Let the engine run during the bleeding process.
Turn the rotary switch to position (D3).
– Move the concave to the widest position by
actuating pushbutton (C7).
Once the concave is closed, leave your finger on
the key (C7) for a further 15 – 20 sec.
Important! Check that the concave adjustment
hydraulic cylinders (H) are fully extended.
– Then move the concave to the closest position by
actuating pushbutton (C6).
Once the concave is closed, leave your finger on
the key (C6) for a further 15 – 20 sec.
Important! Check that the concave adjustment
hydraulic cylinders (H) are fully retracted.
The bleeding process is complete.
(Fig. 39, 40, 41, 42, 43)
2. Checking the basic concave settings:
Measure the basic setting. To do this bleed the
hydraulic cylinders and move the concave to the
narrowest position.
The lengths of the turnbuckles, hydraulic cylinders
and potentiometer linkage must be set according
to the specified dimensions.
