(1) - Thread-pulling knife
(2) - Counter blade
Thread-pulling knife height
The height of the thread-pulling knife is set at the factory using washers
underneath the knife carrier (3).
Important
When changing the knives, make sure that you do not lose the washers.
Thread-pulling knife position
The thread-pulling knife (1) cannot be moved on the knife carrier (3).
Therefore, you will not have to adjust the cutting pressure after replacing
the thread-cutting knife (1).
In rest position, the thread-pulling knife (1) completely covers the cutting
edge of the counter blade (2). This prevents the needle thread from being
damaged.
The pivot range of the thread-pulling knife is 23°.
