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.

Note on the knife holder E:
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.

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 carried 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 grubscrew (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".
