does
NOT
provide consistent roll gap measurements.

3.
Loosen jam nut (A) on both sides of the conditioner.
4.
Turn lower nut (B) counterclockwise until the upper roll
rests on the lower roll. Ensure the rolls intermesh.
5.
Turn lower nut (B) two and a half full turns clockwise to
raise the upper roll and achieve a 6 mm (1/4 in.) roll gap.
6.
Hold nut (B) and tighten jam nut (A) on both sides of the
conditioner.
IMPORTANT:
Make sure the roll gap adjustment nuts are adjusted
equally on both sides to achieve a consistent gap across
the rolls.
7.
If further adjustment to roll gap is required:
•
Turn lower nut (B) clockwise to increase the roll gap.
•
Turn lower nut (B) counterclockwise to decrease the
roll gap.
NOTE:
Make further adjustments to the roll gap based on cutting
performance and crop conditions.
