CONCAVE FILLER PLATES (Fig. L24)
Remove the Barbs
The threshing effect of the concave can be improved by
¿ tting ¿ ller plates A under the ¿ rst concave beaters. Pass
the ¿ ller plates through the holes at both ends of the con-
cave where the springs keep them ¿ xed. A maximum of
four ¿ ller plates can be ¿ tted.
The best way to ¿ t them is through the bottom when the
grain pan cassettes have been ¿ rst removed.
The same ¿ ller plates ¿ t the main concave and the pre-
concave on the TS model.
STRAW WALKER Bottoms Can Be Adjusted
Cassette Bottom Straw Walkers (Fig. L25a)
The bottom cassettes of the straw walkers can be re-
moved for cleaning by releasing clamps A and pulling the
cassettes out through the rear door to the chaff hood.
Closed Bottom Straw Walkers (Fig. L25b)
At the back of the straw walkers there are separately
adjustable extensions A. They can be used to adjust the
separating ef
¿ ciency depending on the conditions. The
extensions can be removed for cleaning.
Chaff Alarm
The switch on top of the chaff hood lights an alarm lamp
on the instrument panel if an excessive accumulation of
straw causes a blockage.
Immediately disengage the threshing mechanism, clear
the blockage and
¿ nd the cause for the trouble before
going on working.
