Setting up the knife holder base

Release the clamping lever (50) by rotating it counterclockwise.

Insert the knife holder base (51) using the notch (52) on the bottom into the T-piece (55) of the microtome base plate (53).

To secure the knife holder base, turn the clamping lever (50) clockwise.

The knife holder base (51) can be moved back and forth on the microtome base plate. This allows bringing the knife holder to optimal sectioning position in relation to the specimen.

There is a scale (54) on the right side of the microtome base plate. This enables faster and better positioning of the knife holder at the specimen if various combinations of standard specimens and specimen holders are used. The rear edge of the knife holder base (51) functions as the scale reference.
