Knife holder CN with anti-roll guide – Moving
the clamping chucks
The large specimen disc (80x50mm) should pref-
erably be used with knife holder CN and the 16cm
C-profile steel knife.
The clamping jaws are factory-installed in the
knife holder with a clearance of 64mm. If neces-
sary, both clamping chucks can be offset with a
clearance of 84mm.
Perform the following steps:
• Use a 3 mm Allen key to loosen the screw over
the clearance angle adjustment (1) and
remove the segment arch (2) from the knife
holder base.
• Use a 3 mm Allen key to loosen the screws (4)
on the underside of the segment arch.
• Carefully pull the clamping jaw (5) on the right
upward and insert it in the neighboring hole
(6). Tighten the screws from the underside of
the segment arch. Repeat on the left side.
• Insert the long knife support (3) on the side
over the knurled screw (3a) so that the recess
faces the user – turn the height adjustment
knurled screws until the lower stop is reached.
• The knife can now be inserted from the side
and its height adjusted via the knurled screws
(3a).

11. Optional Accessories
Never work with only one clamping jaw, as this does not ensure the stability required for the
sectioning process. Also, a long knife will not be sufficiently protected by the knife guard in this
instance.
The specimen disc 50x80mm is suitable
only for section thicknesses up to approx.
5μm (due to the large specimen size).
