CUTTING KNIFE Must Be Kept in Good
Condition!
Actual knife adjustments cannot be made during thresh-
ing. The knife must be in perfect condition to produce
good threshing results. For more precise service and
adjustment instructions, see under Maintenance. A spare
knife is stored in the case at the top of the table.
TABLE AUGER Height and Finger Positions
Are Adjustable
Adjust the height of the table auger and the feed ¿ n-
ger angle to suit the amount of straw in the crop being
threshed. When threshing e.g. heavy rye or turnip rape,
adjust clearance X between the auger and cutting table
wider, approx. 30…40 mm. The adjustment is made in
the following way:
7DEOHZLGWKXSWRP¿J/D
Loosen screws A at both ends of the cutting table. Now
the table auger can be lifted or lowered as required.
Clearance X between the table auger and the bottom
must be equal at both ends of the table. Average clear-
ance is approx. 15 mm. After moving the table auger,
check the feed
¿ nger adjustment and drive belt tension.
Loosen screw E to adjust the feed ¿ nger position using
lever B at the right hand end of the cutting table. A mini-
mum clearance of 10 mm is required between the feed
¿ ngers and the table bottom. The ¿ ngers must recede
into the auger suf ¿ ciently early to allow the crop to be
transported forward.
7DEOHZLGWKVPDQGZLGHU¿J/E
Loosen screws A at both ends of the cutting table. Now
the table auger can be lifted or lowered as required.
Clearance X between the table auger and the bottom
must be equal at both ends of the table. Average clear-
ance is approx. 15 mm. After moving the table auger,
check the feed
¿ nger adjustment and drive belt tension.
Loosen screw D to adjust the feed ¿ nger position using
lever C at the right hand end of the cutting table. A mini-
mum clearance of 10 mm is required between the feed
¿ ngers and the table bottom. The ¿ ngers must recede
into the auger suf ¿ ciently early to allow the crop to be
transported forward.
Correct Height and Tension of the CROP EL-
EVATOR CHAIN (Fig. L9)
The elevator has a ¿ xed top roller and a À oating bottom
roller to enable the elevator to À uctuate according to the
À ow of crop on it. Adjust the clearance between the bot-
tom roller and the bottom of the elevator housing using
screws C. Correctly adjusted, there should be a clear-
ance of 20 mm between the lowest slats and the housing
at middle of bottom roller.
The tension of the crop elevator chain is adjusted with
screws D. To check the tension, open the inspection door
at the top of the elevator housing. The tension is correct
when the de
À ection midway between the top and bottom
rollers is approx. 65-70 mm. If the chain is assembled too
tight, it wears out quickly and in some cases it may even
break.
