Set Maximum Forward Travel Speed (Stop) -

Step 3
1. Position the FSC lever to the most FORWARD
position.
2. Turn the steering lever adjustment nut(s) until
2 or 3 threads are showing past the end of the
nut.
3. Loosen the jam nut at the other end of the
control rod (where it connects to the transmis-
sion control arm).
4. For each steering lever, use a wrench on the
adjustment nut, turn the control rod counter-
clockwise (CCW) until the steering lever be-
gins to move backward, then make two addi-
tional turns. Next, reverse and turn the control
rod clockwise (CW) until the steering lever
stops moving forward and then make one
additional turn. Tighten the jam nut.
NOTE: Failure to make at least one extra
turn on the control rod can place excessive
loads on the transmission internal control
stops and cause internal wear and damage to
the transmission. Making additional turns
beyond one turn reduces the maximum for-
ward travel speed.
