I wrong: anti-roll guide positioned too low
II wrong: anti-roll guide positioned too high
III right: anti-roll guide correctly positioned
In position III the anti-roll plate is correctly adjusted.
It is recommended to first preadjust it at a great sec-
tion thickness (e.g. 10 μm) and then approach the re-
quired section thickness reducing the value in 5 μm
increments and slightly readjust the anti-roll plate in
height with the knurled knob (9, Fig. 20.2).
The glass anti-roll guide is resistant to ac-
etone.
For cleaning the knife holder, domestic deter-
gents can be used.
8. Daily operation
• To raise the anti-roll plate (to move it towards the
blade), turn the knurled knob (9, Fig. 20.2) counter-
clockwise.
• To lower the anti-roll plate (to retract it from the
blade), turn the knurled knob (9, Fig. 20.2) clockwise.
If the anti-roll plate is positioned incorrectly to the blade
edge, problems I and II will occur. Position III shows
the correct position of the anti-roll plate.
