5. Operation
5.1 Operating elements and their functions
The section thickness is set by turning the adjust-
ing knob (33) on the left side of the microtome.
The scaled knob has a notch for each value that
can be set.
Setting range: 0.5 - 60 µm
from 0.5 - 5.0 µm in 0.5 µm increments
from 5.0 - 10.0 µm in 1.0 µm increments
from 10.0 - 20.0 µm in 2.0 µm increments
from 20.0 - 60.0 µm in 5.0 µm increments
The selected section thickness (on the scale)
must agree with the red pointer (38).
5.1.1 Section thickness setting
5.1.2 Coarse driving wheel
The coarse feed serves for fast vertical upward
movement of the object (towards the knife) and
downward movement (away from the knife).
The coarse driving wheel (36) has a direction
selection lever (37) with which you can select the
direction of rotation "upwards" (feed movement of
the specimen towards the knife).
Position of the direction selection lever for feed
motion:

Turning in a clock-
wise direction mo-
ves the specimen
towards the knife.
Turning in a coun-
ter clockwise di-
rection moves the
specimen towards
the knife.
Neutral:
Turning the coarse driving wheel does
not result in a feed motion.
The coarse driving wheel does not turn
as well during sectioning.
