handlebar.
To check:
1. With engine off, select a slow speed.
2. Slowly pull unit backwards.
3. Slowly squeeze wheel drive control until
wheels stop.
4. Measure the distance between the wheel
drive control and handlebar at the
handlebar indentation.
To adjust:
1. If the measurement is more than 2-3/4"
(7 cm), loosen the lower cable nut and
then tighten the upper cable nut against
the adjuster bracket.
2. If the measurement is less than 2-1/4"
(5.7 cm), loosen the upper cable nut and
then tighten the lower nut against the
adjuster bracket.
3. Recheck measurement with the slowest
and fastest speeds selected.
4. Repeat adjustment until wheel drive
control is properly adjusted.
IMPORTANT: If there is not enough thread
length for proper adjustment, contact your
Dealer for repairs before operating unit.
