Step 6 - FSC Neutral Switch Adjustment
1. Place the FSC in NEUTRAL-PARK position.
Loosen mounting screws and adjust switch up or
down accordingly.

IMPORTANT: Disconnect spark plug wires to
prevent the engine from starting when testing
operation of the FSC Neutral Switch.
2. Check operation of the FSC Neutral Switch by
placing the FSC lever fully forward, then holding
the ignition switch in the START position. Slow-
ly move the FSC lever back towards the NEU-
TRAL-PARK position until the starter motor en-
gages and note the position of the FSC lever.
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) the FSC
Neutral Switch needs to be adjusted downward
for quicker activation.
Step 7 - Forward Speed Control Friction Adjustment
FSC Position with Levers
1. Place the FSC in the full FORWARD position
and pull both steering levers 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 move-
ment is “stiff”, the friction needs to be de-
creased.
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.
