Service Instructions M-TYPE DELTA - 00.0 - 12/2019 83
To adjust the cutting pressure:
1. Open the throat plate slides ( p. 28).
2. Turn the handwheel until the thread-pulling knife (3) can be swung out
by hand.
3. Loosen the screw (1).
4. Set the thread-pulling knife (3) so that the marking indicating the
cutting pressure (4) is exactly next to the tip of the counter blade (2).
5. Turn the hook thread clamp (5) so that it rests against the thread-pulling
knife (3).
6. Turn the counter blade (2) so that it rests against the thread-pulling
knife (3).
7. Tighten the screw (1).
8. Check the position of the knife, as the counter blade can easily become
warped when the screw is being tightened.
