2. Loosen jam nut (A) on both sides of conditioner.
3. Turn the spring drawbolt (B) clockwise to tighten
spring (C) and
increase
roll tension.
4. Turn the spring drawbolt (B) counterclockwise to
loosen spring (C) and
decrease
roll tension.
5. Measure the amount of exposed thread on the spring
drawbolt (B) at each end of the conditioner.
The
measurement (D) should be 1/2–9/16 in. (12–15 mm)
for both poly and steel roll conditioners.
IMPORTANT:
Turn each bolt equal amounts. Each turn of the
bolt changes the roll tension by approximately
7.2 lbf (32 N).
6. Tighten jam nuts (A) on both sides.

Roll Timing
IMPORTANT:
Roll timing on is critical when the roll gap is decreased because conditioning is affected, and the bars may
contact each other.
For proper conditioning, the rolls must be properly timed
with the bar on one roll centered between two bars on the
other roll. The factory setting should be suitable for most
crop conditions.
