The resistance felt against the traction control levers
can be adjusted to make the feel less or more
sensitive.
1. To adjust tension loosen nuts on the eye bolts
holding the springs to mounting plate (Fig. 46).
2. To reduce tension thread nuts off eye bolts
(Fig. 46). Tighten nuts to hold new set position.
3. To increase tension thread nuts onto eye bolts
(Fig. 46). Tighten nuts to hold new set position.
Note: Adjust springs to the same length so
tension will be the same on both
motion control levers.
4. If greater tension is desired, the front hook of the
springs can be moved to the outer hole in the
control assemblies (Fig. 46).
