ADJUSTMENTS

Transmission Control

IMPORTANT: The proper adjustment of the transax- le control stops is essential for efficient operation and life of the transaxle. These stops are properly adjusted at the factory and should only require read- justment if the transaxle or related control linkage is removed or changed.

NOTE: It would not be unusual for a new machine, after initial 5 or 10 hours of operation, to begin to not travel straight (this is due to the break-in of the tran- saxles).

Steering Lever Position Adjustment - Step 1

NOTE: For proper operation, the steering levers should be adjusted to sit evenly using the following procedure.

1.Examine the steering levers to make sure they are parallel front to back in relation to one an- other. If they are not equal, adjust accordingly. (The handles may or may not be even at this point.)

NOTE: The LH steering lever is non-adjust- able. This procedure will require adjustment of the RH lever to make it even with the LH lever.

2.Adjust the position of the RH lever by turning the stop bolt in the Speed Control Actuator in or out. Turning the stop bolt in will make the RH lever move back, and turning it out will make it move forward. Tighten the lock nut.

Steering Handles Adjustment - Step 2

1.An adjustment range of approximately 3 inches is available on the steering handles - the han- dles can be adjusted forward or aft depending on the arm length of the operator. The handles can be adjusted by loosening the lock nut at the pivot point and the lock nut holding the handle in position in the adjustment slide. Adjust the han- dles into the most comfortable position and tighten both lock nuts.
