CAUTION
Before testing the FSC Neutral Switch,
disconnect the spark plug wires from the
engine and engage the parking brake to
prevent accidental starting and inadvert-
ent 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
back towards the
NEUTRAL-PARK
position
until 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), the FSC Neutral Switch needs to be
adjusted downward for quicker activation.

FSC Friction Adjustment Test
(Checking Friction Lock)
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 in-
creased.
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.
