Adjusting Roll Gap
–
Steel Rolls
The length of thread extending above the jam nut on the adjustment rods can be used as an approximation of roll gap but
does
NOT
provide consistent roll gap measurements. To ensure the roll gap is at the factory setting, follow the
procedure below:

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.

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 roll gap.
•
Turn lower nut (B) counterclockwise to decrease
roll gap.
NOTE:
Make further adjustments to roll gap based on
performance and crop conditions.
