REVERSE LEVER
3. Squeeze the forward lever against the handlebar and re-
measure the length of the coils. The belt tension is correct
if this second measurement between 1/6 in. to 3/16 in.
(2-5 mm) longer than the first measurement.
4. If the spring is too short (less than 1/16 in. [2 mm]), the
tension is too loose. If the spring is too long (more than
3/16 in. [5 mm]), the tension is too tight.
5. To adjust the length of the spring.
1. Release the forward lever.
2. Un-thread the hex nut halfway up the adjustment
screw.
3. Unhook the top of the spring from the lever.
4. Use pliers to prevent the adjuster from turning and turn
the slotted screw located inside the spring clockwise
(viewed from operator’s position) to increase tension
on the spring. Turn the screw counter-clockwise to
decrease tension. Once adjusted, reattach the spring
to the lever.
5. Repeat Steps 2 and 3 to re-measure the length of the
spring. When the second measurement is between
1/16 in. to 3/16 in. (2 to 5 mm) longer than the first
measurement, re-tighten the hex nut against the top of
the adjuster.

belt Tension Adjustment
Proper belt tension is critical to good performance. After 1/2
hour of operation, all cables may have to be adjusted due to
initial stretch. Thereafter, check tension after every 2 hours of
operation.
To increase belt tension:
1. Turn jam nut clockwise in 1/8 in. (3 mm) increments.
2. Check adjustment.
To decrease belt tension:
1. Turn jam nut counter-clockwise in 1/8 in. (3 mm)
increments.
2. Check adjustment.
3. This procedure can be repeated until conduit adjustment
bolts are fully adjusted. If no more adjustment can be
made, belt may have to be replaced.
