6.9.2 Positioning the Pole Columns
• Find the proper pole position (A, B or C as viewed from the
mechanism side; see illustration) and place the pole column in
this position above the lattice support.
• Slowly lower the pole column. While lowering the pole column,
turn it slightly on its axis in order to avoid damage. Pay special
attention to the gas piping.
• Lubricate the four pole column mounting bolts (4) as per L1 and
insert them from below. Screw on the nuts to the end of the
thread and then loosen them again one half revolution. Do not
tighten the nuts yet. The pole columns will be moved again on the
lattice support during later alignment operations.
The opening springs are located in the crankcases of the pole co-
lumns. The opening springs fix the pole columns in open position.
All other installation steps are based on this open position of the
pole columns.
