Maintenance
The factory adjusts the controls before shipping
the traction unit. However, after many hours of
use, you may need to adjust the traction control
alignment, the neutral position of the traction
control, and the tracking of the traction control in
the full forward position.
Important: To adjust the controls properly,
complete each procedure in the order listed.
