5.9 Aligning the base plate
䡵
First, fix the base plate using the three upper hexagon bolts. Alternately tighten
the bolts until they are all contacting the pedestal. Important: Insert all hexagon
bolts approximately to the same depth!
䡵
Using the lower hexagon bolts, adjust the base plate so that the air bubble is
within the indicator marked ring. Inserting a hexagon bolt will cause the air
bubble to move towards this bolt position. In case of large adjustment travel
(pedestal is outside the vertical position for several degrees), turn the opposite
hexagon bolts counter-clockwise as necessary!
䡵
Alternately tighten all hexagon bolts while avoiding any distortion of the base
plate! Maximum torque: 6 Nm.
䡵
Again check bubble level for correct adjustment.
