20. Place the base structure in its intended
location. Adjust levelers to ensure that the
Beams and Crossbars are level. Ensure that
the three center columns are plumb/parallel.
Adjust the leveling glides to achieve this,
allowing the triangular crossbar structure
to deviate from horizontal, if necessary.
21. Set the outer columns to be plumb/parallel
to the center columns by adjusting the
position of the rails within the center column
cradles (GG/HH), i.e.: reduce/increase
the ³/ " gap, as needed. Once plumb/
8
parallel is achieved, tighten all the screws
(M) in the cradle clamp brackets (D).
22. When levelers are extended more than
½", install the Helical Glide Shroud. See
Helical Glide Installation Instructions.
