Important
The needle bar must be at the top dead center when the handwheel is
at 0° ( p. 43).
The hook bearing must be set correctly ( p. 46).
The height of the thread-pulling knife is determined by the height of the
counter blade. The upper edges of the two knives must be on the same
level.
Thread-pulling knife height
The height of the thread-pulling knife has been set at the factory using
adjusting washers between thread-pulling knife (1) and knife carrier (3).
When changing the knives make sure that you do not lose the adjusting
washers.
Thread-pulling knife position
The thread-pulling knife (1) cannot be moved on the knife carrier (3).
Therefore, you will not have to set the cutting pressure after replacing the
thread-cutting knife (1).
