SERVICE / ADJUSTMENTS
TRACKING
Adjustments to the unit may need to be made if the unit does not track in a
straight line. The primary reason for the unit not tracking straight is incorrect or
unbalanced tire pressure. Before making any adjustments first check and adjust
the tire pressure. DO NOT EXCEED MAXIMUM RECOMMENDED TIRE
PRESSURE.
ADJUST LINKAGE: Place steering levers outward locking them in the neutral
position. Turn off engine and raise seat. Under the seat are (4) adjustment bolts.
The two adjustment bolts toward the seat mount are adjustments for the forward
travel. The two bolts toward the engine or are for the reverse travel. Clockwise
movement for these adjustments will decrease or slow the travel speed of the
individual side. Counterclockwise movement will increase the travel of the
individual side. The linkage is factory set to maximum performance.
Adjustment is made by rotating the adjustment bolt clockwise on the opposite
side that the unit tracks toward. Adjust forward and reverse to track straight as
needed. When accomplished adjustment to the steering levers may need to be
done. This is made by loosening the the two bolts on the steering lever and
aligning with the other. Travel of the steering levers from front to rear may be
accomplished in the same manner.
