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!
Take the knife holder apart for cleaning. To do so,
proceed as follows:
• Fold knife guard (9) downward.
• Rotate the clamping lever (11) of the lateral
displacement forwards and pull it out sideways.
• Push the knife holder base plate (86) with the
pressure plate (83) until it can be removed from
the segment arch (87).
• Rotate the blade clamping lever (10) downward
and pull it out sideways.
• Remove pressure plate (83).
• Clean all parts of the knife holder.
There is a burn hazard when remov-
ing the parts from the drying chamber
(65 °C). Wearing safety gloves is rec-
ommended!
For cleaning and removal of paraffin, do
not use xylene or cleaning fluids contain-
ing alcohol (e.g. glass cleaner).
• Dry knife holder and reassemble.
• After cleaning the moving parts, apply a thin coat
of drive part oil to them ( refer also to Chapter 8.3 ).
• When installing the pressure plate (83) make sure
that the upper edge is parallel and level with the
rear edge of the knife holder base plate (86).
