Trimming the specimen
Take care when handling microtome knives and disposable blades. The cutting edge is
extremely sharp and can cause serious injuries. For that reason, always wear the cut-
resistant safety gloves included in the standard scope of delivery!
Always clamp the specimen block BEFORE clamping the knife or the blade.
Lock the handwheel and cover the knife edge with the knife guard prior to any manipu-
lation of knife/blade or specimen, prior to changing the specimen block and during all
work breaks!
• Insert the precooled knife/blade in the knife/blade holder.
• Adjust the appropriate clearance angle on the knife holder. Settings from 4° - 6° (knife holder
CN and blade holder CE-TC) or 1° - 2° (blade holder CE) are suitable for most applications.
• Align the knife holder/knife or blade holder/blade with the specimen.
• Remove the knife guard (knife holder CN) or fold the glass anti-roll guide (knife holder CE,
CE-TC) over to the side.
• Unlock the handwheel.
• To trim the specimen, move the specimen towards the knife using the coarse feed but-
tons. Trim the specimen down to the required sectioning plane by turning the handwheel.
