5. Operation
In some cases, e.g. for large specimens, it is
necessary to move the blade holder (50) on the
mounting bar.
When the width of a large specimen is approxi-
mately the same as the sectioning blade edge
length, the lateral positioning of the sectioning
blade may have to be adjusted to ensure com-
plete sections.
• By loosening the knurled screw (48), you can
move the blade holder sideways along its
axis (49) and thus position it more accurately
relative to the specimen ( Fig. 45 ).

Moving the blade holder relative to the specimen
Because the knurled screw (48) is also
used to adjust the blade presentation
angle, the angle may have changed.
Therefore, recheck the blade angle af-
ter this adjustment.

Adjusting the tilt of the specimen
If the specimen is still not completely horizon-
tal, you can tilt the specimen along another axis
(from side to side).
To do so, tilt the specimen mounting block
slightly when it is clamped in the jaws of the
specimen holder.

Complete control of the specimen over
all three axes is possible with the ro-
tating stage assembly (see Chap. 7.2 ,
Optional Accessories).
