ADJUSTMENTS
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
po sition check for movement of either
drive wheel (if either wheel moves backward or
forward, re
fer to

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 refer-
ence).
3. If tracking is not straight, shorten the control rod
on the faster side by turning the tracking adjust-
ment nut clockwise. If straight tracking and
neutral are both achieved, proceed to the next
step. If straight tracking and neutral cannot
both be achieved, turn the tracking adjustment
nut on the faster side counterclockwise until
neutral is restored.
4. Lengthen the control rod on the slower side by
turning the tracking adjustment nut counter-
clockwise until straight tracking and neutral are
both achieved.
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 until
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. Raise the body and adjust the switch
adjustment bolt up until it just makes contact
with the FSC switch plunger, and then turn the
switch adjustment bolt up an additional two (2)
turns and tighten the jam nut.
NOTE:
It may be necessary to tighten the FSC
friction adjustment if the transmissions are
moved out of neutral when the body is raised.
