of the cut edge of the sewn material. For thinner materials, both cutting
edges should be parallel, with thicker materials, a demand may arise to
slightly turn the front part of the upper knife in the direction of the
bottom knife cutting edge.

located on the bottom of the upper knife holder (3).

required holder turning (3).

After setting the needed crossing of the cutting edges, tighten the
bolt (2) again.

lowering of the upper knife, and set the lateral position of the knife
again as needed in accordance with 7.4.
