Adjusting blade holder with anti‑roll system
You can adjust the height of the anti-roll system
using the knurled nut (1):
• If you turn the nut counterclockwise, the anti-
roll system moves toward the blade.
• If you turn the nut clockwise, the anti-roll
system moves away from the blade.
If the anti-roll system is in the wrong position
relative to the blade, the following problems will
result:
Fig. 15: Premium blade holder with anti‑roll system
Fig. I:
Fig. I: The section rolls over the glass insert of the anti-roll system.
Error: Glass insert not high enough.
Remedy: Turn the knurled nut counterclockwise until the section is pushed between
the blade and anti-roll system as shown in Fig. III.
Fig. II:
Fig. II: Section tears and block hits the glass insert after sectioning.
Error: Anti-roll system is set too high.
Remedy: Turn the knurled nut clockwise until the section is pushed between the blade
and anti-roll system as shown in Fig. III.

We recommend pre‑adjusting the anti‑roll system at a high section thickness (e.g. 10 µm). Start
from there and work your way down to the desired section thickness in small increments, read‑
justing the anti‑roll system at each increment using the knurled nut.
