• Insert the long knife support (3) on the side
above the knurled screw (3a) so that the
recess (24) 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). The upper edge of the rear clamping jaw
serves as an index point for the correct knife
height. The height of the knife blade should
match that of the rear clamping jaws. This
makes it possible to accurately adjust even
greatly worn knives up to a height of 25 mm.
• Once the correct height is obtained, tighten
the wingscrews (7) in alternating order until
both are tight.
• To remove the knife, follow these instructions
in opposite order.
Open the wingscrews by turning them coun-
terclockwise and then pull the knife out to the
side.

After removing the knife from the knife
holder, place it safely into the knife
case. NEVER place it onto the work
surface next to the instrument!
The height of resharpened knives must be adjusted using knurled screws (3a) (approx.
1mm under the edge of the clamping jaw).
Make sure that the knife is parallel from one end to the other.
The safety gloves included in the standard scope of delivery must be worn when insert-
ing/ejecting the knife!
