Setting steps

2. Turn the handwheel until the thread-pulling knife (6) can be swung out
by hand.
3. Pivot the thread-pulling knife (6) as far forward until the circle mark is
exactly next to the tip of the counter-blade (5).
4. Set the handwheel position to 60°.
5. Push the control cam (3) to the left as far as it will go and against the
clamping ring (2).
6. Turn the control cam (3) such that the roller (1) runs up at the contour
of control cam (3) and the widest extent of the control cam is at hand-
wheel position 60° at the highest point.
7. Tighten the setscrews (4).
8. Check setting:
• Insert the thread into thread-pulling knife (6) and slowly turn the
handwheel.
• Determine the handwheel position at which the thread is cut.
