WHEEL DRIVE CONTROL ADJUSTMENT (self-propelled
models)
See Figure14.
The wheel drive must start to engage when
wheel drive control is between 2-1/4" and
2-3/4" (5.7 and 7 cm) away from the
handlebar.
To check:
1.With engine off, select a slow speed.
2.Slowly pull unit backwards.
3.Slowly sque eze wheel drive control until
wheels stop.
4.Measur e 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"
(7cm), loosen t he lower cable nut and
then tighten the upper cable nut against
the adjuster bracket.
2.If the measurement is less than 2-1/4"
(5.7cm), loosen the upper cable nut and
then tighten the lower nut against the
adjuster bracket.
3.Recheck measurem ent 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.
SPEED CONTROL BELL CRANK (self-propelled models)
The speed control bell crank holds the speed
control rod in position after a speed has been
set. The spring washers may become loose
with normal wear. If the speed control rod
does not stay firmly in position, adjust the
speed control bell crank. See Figure 15.
To adjust:
1. Remove cover, fully compress the
helical spring lock washers with lock
nut and then back lock nut off, one
quarter turn.
2. If the speed control rod is still too
loose, tighten lock nut by small
increments until it holds its position.
Tightening the lock nut too much will
not allow the speed control rod to
move at all.
3. Align notch in left hand side of cover
with bolt and secure with knob.
