9.2 Adjusting the gear racks
 Turn column into center position.
 Release the locking nut widely enough, so it will not obstruct tightening (pos. 2 fig. 17).
 Tighten the bolt (pos. 1, fig. 17) against the gear rack with 20-25 Nm (2-2,5 kg*m).
 Tighten the locking nut (pos. 2 fig. 17).
 Repeat same procedure with both bolts.
 Make sure you adjust bolts after every 200 working hours.
 With professional everyday usage, tighten bolt at least once a month.
