1. Operation
I
Use the knurled nut to height-adjust the anti-roll
system:
•
rotate counterclockwise to move the anti-roll
system towards the knife;
• rotate clockwise to move the anti-roll system
away from the knife.
If the anti-roll system is not correctly adjusted
relative to the knife edge, the following problems
occur:
Fig. I: The sections roll up on the
glass plate of the anti-roll system.
Problem: glass plate situated too
low. Solution: rotate knurled nut
counterclockwise until the section
slides down between blade and
anti-roll plate as shown in Fig. III).
Fig. II: The sections tear and after
each section the specimen block
collides with the glass plate.
Problem: glass plate situated too
high. Solution: rotate knurled nut
clockwise until the section slides
down between blade and anti-roll
plate as shown in Fig. III).
We recommend pre-adjusting the
anti-roll system at a relatively high
section thickness setting (e.g. 10
µm). – From there, slowly decrease
the section thickness, slightly read-
justing the anti-roll system via the
knurled nut (see description above)
each time you select a lower sec-
tion thickness setting.
