Arm Leveling Adjustment
Fix the Pillar to the mounting surface using M10 (4x) fasteners. Do not tighten fully, in order to leave opportunity for leveling adjustment after completion of installation.
After completion of installation, verify that the pillar mounting bolts have been loosened.
Adjust set screws until the desired leveling position is reached.
Tighten jam-nut, on set screw, to ensure the set screws do not move freely.
Re-tighten the mounting bolts to fully secure the pillar.
