Warning
The knife/blade is installed before the knife/blade holder and the knife/blade holder base are installed
on the instrument.
Serious injury of persons due to contact with extremely sharp knives and/or blades.
• Prior to inserting the knife/blade, both the knife/blade holder and the knife/blade holder base must
be installed on the microtome.
Inserting the knife
• Rotate the knurled nuts ( → "Fig. 42- 3 ") on the right and left of the knife holder forward in opposite
directions, lowering the knife support bar to the lowest possible position, thus ensuring that the knife
edge will not be damaged when inserting the knife.
• Unscrew the clamping screws (

knife.
Knife height adjustment
When adjusting the knife height, the knife edge should be positioned as exactly as possible in the actual
center of rotation of the knife holder. The lay-on edge
( → "Fig. 42- 6 ") of the rear clamping chucks serves
as a reference position for correct knife height adjustment.
• Rotate the knurled nuts (
→
"Fig. 42- 3 ") uniformly and backwards until the knife blade is parallel to the
marks on the lay-on edges (
→
"Fig. 42- 6 ") of the rear clamping chucks.

→
"Fig. 42- 5 ") evenly screw the two knife clamping screws (
→
"Fig. 42- 4 ") inward
(rotate clockwise).
Lateral repositioning of the knife

→
"Fig. 42- 1 ") to the center.
• Loosen the clamping screws (
→
"Fig. 42- 4 ") by turning them counterclockwise.
• Push the knife (
→
"Fig. 42- 5 ") to the left or right as required.
• After the knife has been repositioned, adjust the knife height (
→
P. 58 – Knife height adjustment) ,
