Model IZT 915055, 057, 059, 067, 501 with serial numbers above 10,000

IMPORTANT: The unit should track within 2 feet (0.61 m) of a straight line for 30 feet (9.14 m).

The travel of the steering levers may need adjustment if:

•The unit turns to the right or left when both steering levers are pushed as far forward as possible.

•The unit turns to the right or left when both steering levers are pulled back as far rearward as possible.

NOTE: The side the unit turns toward indicates that the wheel on that side is turning slower than the other wheel. Either the wheel that is turning faster needs to slow down or the wheel that is turning slower needs to be sped up to allow the unit to travel in a straight line.

See steering section for illustrations.

1.Determine which way the unit turns.

2.Tip seat forward

NOTE: The forward travel adjustment bolt adjusts forward travel of the steering lever. The rear travel adjustment bolt adjusts the rearward travel of the steering lever.

3.Adjust speed by:

•Turning adjustment bolt clockwise to decrease steering lever travel.

4.Turning adjustment bolt counterclockwise to increase steering lever travel.
