Lateral displacement (only for knife holder E)
The lateral movement feature of the knife
holder base enables the use of the entire length
of the blade or knife, eliminating the need for re-
adjusting 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
notch point.
• 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 Microsystems 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
"bars" when the lever is activated. Continue
turning the grubscrew (12) a little bit (approx.

turn to the left or right), then check that the
lever no longer "bars", but also does not jam
"heavily".
