CAUTION
Before testing the FSC Neutral Switch, dis-
connect the spark plug wires from the en-
gine and engage the parking brake to pre-
vent accidental starting and inadvertent
machine movement.
2. Check operation of the FSC Neutral Switch by
placing the FSC lever in the full
FORWARD
position. 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 position 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
NEU-
TRAL-PARK
position. If this distance is great-
er 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 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 ad-
justment nut.
Loosen or tighten the nut and
check the control function until the conditions
of both steps 1 and 2 (above) are met.
