CAUTION
Before testing the FSC Neutral Switch,
disconnect the spark plug wire from the
engine and engage the parking brake to
prevent accidental starting and inadver-
tent machine movement.
2. Check operation of the FSC Neutral Switch by
placing the FSC lever in the full FORWARD po-
sition. While holding the ignition switch in the
START position, slowly move the FSC lever to-
ward the NEUTRAL-PARK position and stop
when the starter motor engages. Note the posi-
tion of the FSC lever where it passes through
the slot in the body. The FSC lever should be
within 1/8 in. (3 mm) of the NEUTRAL-PARK
position. If this distance is greater than 1/8 in.
(3 mm), turn the adjustment bolt down slightly
and recheck switch operation. When nished
adjusting, tighten the jam nut and reconnect the
spark plug wire.
Step 7 - Forward Speed Control Friction Adjustment
FSC Friction Adjustment Test
1. Place the FSC lever in the full FORWARD
position, and pull both steering levers fully back;
the FSC lever should not move. If the FSC lever
moves back the friction needs to be increased.
2. With the steering levers held back, move the
FSC lever back from the FORWARD position.
With a proper amount of friction adjusted, the
FSC le ver should move back with a slight
amount of re sistance (friction). If the FSC lever
movement is “stiff”, the friction needs to be
decreased.
3. The FSC friction is increased or decreased by
tightening or loosening the friction adjust-
ment nut. Loosen or tighten the nut and check
the control function until the conditions of both
steps 1 and 2 (above) are met.
