The support plate 3 must be close and movable without clearance.
Insert or remove discs 4 of 0.1 mm, if necessary.
The thread puller 5 has to be aligned in such a way that it is at the
same level with the thread rest 6. By no means the thread puller 5
must stand under the thread rest 6 because otherwise the support
plate might be lifted and the knives could collide.
When exchanging the knives take care that the edge of the left knive
stands a little lower than the edge of the right knife.
