The control is also performed here at the 3, 6, 9 and 12
o'clock positions.
If the foil under the tool is to be perceived at each position
and on each spherical shell, i.e. if the foil is found to be clam-
ped, the instrument can be considered to be in order for
milling. If no resistance is perceptible, the instrument must be
adjusted. This adjustment procedure is described in the
following section.

The two fixation screws on the left under the connection
element for the spherical shells should be loosened slightly
using a 3 mm Allen wrench.

Apply adjusting bar to the calibration plates of the spherical
shells, turn off the vacuum using the foot switch. At the same
time, manually put pressure on the middle of the bar and thus
at the same time on the spherical shells. Thus, the spherical
shells are aligned with the planed bar. Turn on vacuum again
by releasing the foot switch.
Tighten both fixation screws once again.
By means of control foil, check the alignment of both
spherical shells once again in all positions and, if necessary,
perform a readjustment.
