• Push the knife holder base plate (86) with the pres-
sure plate (83) until it can be removed from the
segment arch (87).
• Rotate the blade clamping lever (10) downward and
pull it out sideways.

• After cleaning the moving parts of the knife holder,
apply a thin coat of drive part oil to them (see also
Chap. 8.2.3 ).
• When installing the pressure plate (83), ensure that
the upper edge is parallel to and level with the rear
edge of the knife holder base (86)(see also Fig. 42 ).
There is a burn hazard when remov-
ing the parts from the drying chamber
(65 °C). Wearing safety gloves is recom-
mended!
• Lay the removed parts on an absorbent cloth into
the drying chamber (up to a max. of 65 °C) and let
the paraffin contamination run off.
• Dry knife holder and reassemble.
For cleaning and removal of paraffin, do
not use xylene or cleaning fluids con-
taining alcohol (e.g. glass cleaner).
If several knife holders are cleaned at
the same time, the parts must NOT be
mixed up! Failure to adhere to this may
result in sectioning problems!
