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 al-
lows bringing the knife holder to optimal section-
ing position in relation to the specimen.
There is a scale (54) on the right side of the mi-
crotome base plate. This enables faster and bet-
ter 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.
