For proper conditioning, the rolls must be
properly timed and aligned with each steel bar
on one roll centered between two bars of the
other roll as shown. The factory setting should
be suitable for most crop conditions.

steel bar on one roll should be centered
between two bars of the other roll so that
distance ‘X’ is 0.5 in. (12 mm).
NOTE
If the distance ‘X’ varies more than
1/16 in. (1.6 mm) from one end to the
other, the rolls should be re-aligned.
Refer to next Section 6.17.11.2.2 Roll
