C CONDITIONER ADJUSTMENTS
C.1Moving the conditioning rotor
If the conditioner tends to get frequently clogged when
working in long crops it is advisable to move the rotor to the
rear as follows:
- Open the V belt housing to relieve V belt tension.
- Remove the tension from the V-belts.
- Dismount the threaded end of the tensioning device by
removing the bolt A (fig. C-1).
- Dismount the top bolt B (fig. C-2) of the bearing blocks
(left and right side).
- Losen the lower bolt of the bearing blocks.
- Move the conditioner rotor to the rear, from the position

to the position  (or the other way round). Then tighten
both bolts.
- Mount the threaded end of the tensioning device.
- Tighten the V-belts. Adjust belt tension in such a way that,
if a 70 N (7 kg) force is exerted on the middle, the V-belt is
pushed in 10 mm (fig. C-1).
- Close and lock the V belt housing.
C.2Rotor speed
The machine can be supplied together with an additional
drive pulley (option) for the conditioner rotor. By exchanging
this pulley with the standard part, a different rotor speed can
be adjusted.
- Open the V belt housing.
- Remove the tension from the V-belts and remove them.
- Remove the two allen headed bolts B (fig. C-1) from the
pulley and place one of the t wo bolts in the central one of
the three holes in the pulley.
- Tighten the allen headed bolt until the pulley is detached
from its clamping bush.
- Remove the clamping bush and pulley.
- Fit the other pulley (align it with the top pulley) and tighten
the allen headed bolts with a torque of 50 Nm (5 kgm).
Then hit the pulley with a hammer and tighten the allen
headed bolts once again at the same torque (50 Nm/5 kgm).
Do not use any oil or grease when fitting the pulley.
