Maintenance Instructions ADJUSTMENTS
5. If the forward travel is straight throughout the
speed range, except at maximum speed place
the FSC in full FORWARD, turn the set screw in
the Transmission Control Arm, of the faster
side, in until it contacts the limit stud. (Turning
the set screw in slows the wheel.) Turn the set
screw in an additional 1/8 turn. Recheck for
equal full for ward speed. Adjust this set screw
until equal full forward speed is achieved. Tight
en the jam nut.
Step 6 - FSC Neutral Switch Adjustment
1. Place the FSC lever in the NEUTRAL-PARK
position. Loosen mounting screws and adjust
the neutral switch up or down accordingly.

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. Stop moving
the lever and 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 NEUTRAL-PARK position. If this dis
tance 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 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.
