Note
The theoretical distance of the ceph arm from the wall is 11mm. In the
presence of irregular wall it’s good to prescribe the use of a C washer (code
5604103400) before attaching the ceph arm to the machine. One C washer
is already glued from factory.
Supplied with Prime Ceph there are 2 C washers (code 5604103400) to tilt
the fixing of the column and move the ceph arm away from the wall (each
mm on the column moves the ceph about 1 cm away).
The C shape allows it to be applied even when the column is already screwed to
the wall.
