3. Loosen and back off upper jam nut (A) on both sides
of conditioner.
4. Turn stop nut (B) counterclockwise until upper roll rests
on lower roll. Ensure both rolls intermesh.
5. Turn stop nut (B) one full turn clockwise to raise the
upper roll and achieve a 1/8 in. (3 mm) roll gap.
NOTE:
the amount of thread (C) protruding through the jam
nut is equal to the roll gap.
NOTE:
When adjusting roll gap, be sure the same amount of
thread is protruding on both sides of the conditioner
roll to achieve a consistent gap across the rolls.
6. Tighten jam nuts (A) on both sides.
7. Rotate the rolls manually and use a feeler gauge at the
ends of the rolls to check that the actual gap is no less
than 5/64 in. (2 mm) and no more than 5/32 in. (4 mm).
3.15.7 Roll Tension
Roll tension (the pressure holding the rolls together) is factory-set to maximum and is adjustable.
Heavy crops or tough forage can cause the rolls to separate; therefore, maximum roll tension is required to ensure
that materials are sufficiently crimped.
To prevent over-conditioning of light alfalfa and short grasses, apply less roll tension.
Adjusting Roll Tension
Roll tension is factory-set to maximum and can be adjusted as follows:
