Align the hole on the end of the lower control
rod (

Note:
The lever on the control tower should be
in the center of the slot (neutral position) if the
control rods are adjusted correctly (

If the lever on the control tower is not in the
center of the slot, adjust it by threading the lower
rod into or out of the upper control tube. After
each lever is adjusted, check to ensure that all
levers are aligned with each other. Readjust the
levers if necessary.

Check the control lever operation by moving the
levers to the raise and lower positions. All of
the levers should operate freely with no binding
and should be well lubricated. Readjust the
