Lateral displacement (only for knife holder E)
The lateral displacement feature of the knife
holder base enables the use of the entire length
of the blade, eliminating the need for readjusting
the knife holder. The knife holder E consists of a
segment arch A (with lever (11)) and the clamp
mount B (with lever (10) and ejector (13)).
The extreme left and right positions as well as
the middle position are each marked with a click
stop.
• To release the clamp, rotate the lever (11) on
the left side of the knife holder forwards.
• Move the knife holder sideways.
• To clamp, rotate the lever (11) back.

To ensure a proper sectioning result, clamp
mount B must be securely clamped onto segment
arch A.
The clamping is carried out using an eccentric
at the lever (11). The clamping force is adjusted
with the setscrew (12) on the underside of the
segment arch. The setting of the clamping is car-
ried out so that the clamping lever can be rotated
to the stop with constantly increasing resistance.

Adjust the clamping with a 2.5 mm Allen key at
the setscrew (12) so that the lever initially "slips"
when the lever is activated. Continue turning the
setscrew (12) a little bit (approx. 1 /
4
turn to the
left or right) then check that the lever no longer
"slips", but also does not jam "heavily".
(The language CD features a short video film for
this purpose.)

The knife holder E is an important precision component, the quality and precise adjustment of
which have a lasting effect on the entire function of the microtome. In case of malfunctions or
damages to the clamp mount, it is always required to replace the clamp mount, including the
pertinent clamping lever.
Leica Biosystems offers special prices for new clamp mounts in case of damages to the clamp
mount after the warranty has expired.
In this way, perfect function of the device can be ensured over the course of many years.
