2. Open the throat plate slide ( p. 20)
3. Loosen the threaded pins (6).
4. Turn the handwheel until the thread-pulling knife (4) can be swung out
by hand.
5. Swivel the thread-pulling knife (4) forward until the circle mark is exactly
next to the tip of the counter blade (5).
6. Set the handwheel position to 60°.
7. Push the control cam (3) to the left as far as it will go and against the
clamping ring (2).
8. 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.
