16. Place a surface level on the top surface of the lower azimuth pivot pin and
adjust (3) equally spaced 3/4-10 X 3.0 screws on the base plate until the pivot
is level. Tighten three of the six top nuts against the base plate to 240 ft-lb
(325 Nm).
17. Check the level to ensure the lower azimuth pivot pin is level.
18. Rotate the remaining (3) bottom nuts and (3) top nuts against the base plate.
Caution must be taken not to distort the leveled pin. Tighten all anchor nuts
