• Dry knife holder and reassemble.
• After cleaning the moving parts of the knife holder,
apply a thin coat of drive part oil to them ( Also refer
to 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. 43 ).
There is a burn hazard when removing the
parts from the drying chamber (65 °C). Wear-
ing safety gloves is recommended!
For cleaning and removal of paraffin, do not
use xylene or cleaning fluids containing al-
cohol (e.g. glass cleaner).
• 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.
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 sec-
tioning problems!
