4. There is now
sufficient slack in

the drive control.
See Figure 20.
IMPORTANT! Make
sure to insert the
z-fitting into the rear
hole as it was inserted

from the outside of the drive control.
5. You may now carefully reinstall the drive control by performing the previous
steps in the opposite order and manner of removal.
IMPORTANT! Once assembled and prior to restarting, make sure that the cable is properly
adjusted. With the drive control disengaged, the unit should freely pull in reverse.
