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 18.
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.
