Prior to setting the clearance angle, the knife
edge must be located exactly in the spin axis of
the knife holder.
First, set a clearance angle of '0'. To do so, loos-
en lever (23, see Fig. 11) and bring the index
marker (26) in line with the figure '0' on the clear-
ance angle scale (27). Retighten the lever (23). If
the sectioning results obtained are not satisfac-
tory, slowly increase the clearance angle in 1°
steps, until the desired section quality is
achieved.
