Loosen the nuts holding the tine engagement cable to the tiller
body. Move the cable away from the drive pulley to tighten belt
tension or toward the drive pulley to decrease belt tension,
re-tighten the nuts.
To increase belt tension:
1. Turn jam nut clockwise in 1/8 in. (3 mm) increments.
2. Test the travel distance of the engagement lever again to see
if travel before full engagement is less than 5/8 of an inch.
If it is still more than 5/8 readjust the cable. Note, if there is
no more cable adjustment left the belt has become stretched
and will need replaced.
