5.1 Operating elements and their functions
5.1.1 Section thickness setting
Fig. 11

The section thickness is set by turning the
adjusting knob (
→
"Fig. 11- 3 ") at the front of the
microtome on the right.
Setting range: 1 - 60 µm
from 1- 10 µm in 1 µm increments
from 10 - 20 µm in 2 µm increments
from 20 - 60 µm in 5 µm increments.
The section thickness set in each case is
displayed in the window ( → "Fig. 11- 2 ") .
The selected section thickness (on the scale)
must agree with the red pointer (
→
"Fig. 11- 1 ") .
5.1.2 Coarse feed wheel

The rotation of the coarse feed wheel
(
→
"Fig. 12- 1 ") can be set as clockwise or
counterclockwise to advance the object head.
The adjusting slot (
→
"Fig. 12- 2 ") is located at the
rear plate of the instrument. Use the flat screw
driver (supplied with the delivery) to turn the slot
into horizontal position (clockwise) (
→
"Fig. 12- 3 ")
or vertical position (counterclockwise) (
→
"Fig.
12- 4 ") .
The coarse motion serves for a fast horizontal
forwards movement of the specimen - towards
the knife - and backwards - away from the knife.
When reaching the rear/front end positions,
the coarse feed wheel can only be turned with
difficulty. In the front end position, no more feed
motion takes place.
Caution
Rotating the handwheel and the coarse feed wheel at the same time.
Specimen damage.
• Do not turn the coarse feed wheel whilst rotating the handwheel.
