ADJUSTMENTS
4. With the body lowered and the FSC in
NEU-
TRAL-PARK,
start the engine. With the engine
at normal operating speed, check for movement
of the drive wheels.
5. Lift the body to access the steering adjustment
components.
NOTE:
It may be necessary to tighten the FSC
friction adjustment if the transmissions are
moved out of neutral when the body is raised.
Refer to
Step 7 -
Forward Speed Control Friction
Adjustment
later in this section for location of
the FSC friction adjustment nut.
6. Using a wrench on one tracking adjustment nut,
rotate the control rod
clockwise
just until the
wheel on that side begins
to move
forward.
Then, counting the turns required, rotate the
control rod
counterclockwise
just until the
wheel stops and then begins
to move in re-
verse.
Rotate the control rod back clockwise
half the number of turns required to make the
wheel go from moving forward to reverse. The
transmission is now centered in the neutral win
dow. Tighten the jam nut on the ball joint and
repeat the same procedure on the other trans
mission.
7. Turn off the engine, and then lower the drive
tires onto the ground.
Step 4 -
Full Forward Speed Adjustment
1. Move the FSC to the full
FORWARD
speed
position.
2. Raise the body. The maximum speed tracking
adjustment set screw in both transmission
control arms should not be contacting the limit
stud on the transaxle. If they are, back the set
screws out until they do not touch.

Step 5 -
Straight Tracking Adjustment
1. Sit in the seat, start the engine, set throttle at full
speed, and with the FSC in the
NEUTRAL-
PARK
position check for movement of either
drive wheel (if either wheel moves backward or
for ward, refer to
Step 3 -
Neutral Function
Adjustment
and readjust).
2. Check for straight ground tracking on a level
surface (with hands off the steering levers). Set
the FSC at several different speeds and ob
serve if the machine moves in a straight line
(use cement joint or other line on ground for
reference).
3.
If travel is not straight, shorten the control rod
on the slow side by turning the tracking adjust
ment nut clockwise. If straight tracking and
neutral cannot be achieved, turn the tracking
adjustment nut counterclockwise until neutral is
restored.
4. Lengthen the control rod of the faster side by
turning the tracking adjustment nut counter
clockwise to match the slower side while main
taining the neutral position.
IMPORTANT:
After tracking adjustments are
complete, confirm that there is at least one (1)
thread visible on both control rods past the
tracking adjustment nuts.
5. If the machine is tracking straight throughout
the speed range except at maximum speed,
use the following adjustment procedure:
a. With the engine off, place the FSC in full
FORWARD.
On the faster transmission,
loosen the jam nut and turn the maximum
speed tracking adjustment set screw in un
til it just contacts the limit stud, and then
turn it in an additional 1/8 turn (turning the
set screw in slows the drive wheel).
b. Recheck maximum speed tracking, and if
necessary continue adjusting the set screw
in small increments until straight travel is
achieved.
c. Tighten the jam nut.
Step 6 -
FSC Neutral Switch Adjustment
1. Place the FSC lever in the
NEUTRAL-PARK
position. Loosen the FSC neutral switch mount
ing screws and adjust the neutral switch up or
down accordingly. Refer to
FSC Neutral Switch
Adjustment
illustration.
