Operation
Knife support bar
Ensure that the recess (24) is pointing
away from the microtome.
Danger!
Microtome knives and blades have ex-
tremely sharp cutting edges! Never try
to catch a falling knife!
Clearance angle adjustment
The harder the specimen the wider the
clearance angle. However: the wider
the clearance angle the greater the com-
pression of the sections.
Clearance angle adjustment - knife holder CE
8
If the clearance angle is too small, thick-
thin sections may result.
Also, remember that by adjusting the
clearance angle, the position of the knife
edge relative to the specimen may be al-
tered.
Therefore, always place the specimen
block above the knife prior to adjusting
the clearance angle. Otherwise, the
specimen block may collide with the
knife when it is moved back upwards.
Readjust the clearance angle with every new
type of specimen material!
1. The clearance angle scale is located on the
left side of the knife holder.
2. Loosen the lever (23, Fig. 11) on the right side
of the knife holder and select a clearance
angle setting of '0' (index marker (25) must be
in line with figure '0'). Retighten lever (23, Fig.
11). If the sectioning results are not satisfac-
25
tory, increase the clearance angle setting in
1° steps, until the desired result is achieved.
