6.8. Adjustment of the pressure between the rollers
The factory setting of the pressure between rollers should be adequate. If it appeared that it is too loose
or too tight it can be corrected through changing the tautness of the spring S (Pict 23) by turning
the nut N. Change in pressure should be done on both sides of the roller by the same measure (number
or turns of the nut).

6.9. Maintenance
6.9.1. Checking the blades and blade holders
All blades should be of equal length and have the same weight. If necessary, blades should be replaced
with new sets of matching length and weight. The blade holder shafts can not be worn to a greater
degree than what is shown on Pict 24. Excessively worn shaft should be replaced.
Pict 24. Acceptable wear of the disc blade holder.
WARNING:
The loss of a blade can cause vibrations which can lead to damage of the cutting
bar. In such cases warranty claims will be rejected. In the event of blade damage
the whole set (2 pcs) should be immediately replaced.
