4. Noises during sectioning
The knife "sings" when section-
ing hard specimens. The sec-
tions show scratches or chatter
marks.
• The sectioning speed is too fast.
• The clearance angle is too
wide.
• Insufficient clamping of speci-
men clamp and/or knife holder.
• Select a slower sectioning
speed.
• Methodically reduce the clear-
ance angle setting until you have
found the optimum angle.
• Check all screw and clamp con-
nections on the specimen holder
system and the knife holder. If
necessary, tighten the levers and
screws.
5. High blade consumption • Too great of a sectioning force
was applied.
• Adjust the sectioning speed and/
or section thickness when sec-
tioning. Select a thinner section.
