even a pet could engage the drive.
a. Lower header fully, stop engine, and remove
key.
I. ROLL GAP
a. Check roll gap is mark 1 on the decal (A).
b. If required, adjust the stop (B).
NOTE
When adjusting roll gap, be sure that the
decal reading is the same on both sides of
the conditioner roll to achieve consistent

access port (E) at each end of conditioner.

each end of the rolls (E). Each steel bar on one
roll should be centered between two bars of the
other roll, so that distance ‘X’ is 1/2 in. (12 mm).
c. If required, adjust the roll timing as follows:
1. Loosen four bolts (F) in slots of yoke plate
on lower roll universal shaft.
2. Turn rolls to achieve best timing.
3. When roll timing is satisfactory, tighten bolts
(F) to secure the position.
