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 con- trol 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 forward, refer­ to Step 3 - Neutral Position 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 observe if the machine moves in a straight line (use cement joint or other line on ground for reference).

3.If tracking is not straight, shorten the control rod on the faster side by turning the tracking adjustment 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. Then, lengthen the control rod on the slower side by turning the tracking adjustment nut counterclockwise until straight tracking and neutral are both achieved.

IMPORTANT: After tracking adjustments are complete, confirm that there is at least one (1) thread visible on both control rods past the track- ing adjustment nuts.

4.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-PARKposition. 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. Refer to Step 7 - Forward Speed Control Fric- tion Adjustment later in this section for location of the FSC friction adjustment nut.
