7.8.3 Depth-control wheels (not with R*SU).
Axial clearance of the wheel stalk of the depth-control wheels must be readjusted as
follows, in case of need:
– Screw out the threaded rod (1) using a hexagonal recess wrench and keep it in a
safe place.
– Readjust the setting nut (2) so far until it axially touches the collar of the brass
bushing. Then, turn back the setting nut (2) so far until the threaded rod (1) can be
screwed into the next groove (3).
