16.1 Setting the height of the thread-pulling knife
Fig. 61: Setting the height of the thread-pulling knife
The height of the thread-pulling knife is factory-set so that the
distance between the thread-pulling knife and the middle part of the hook
is 0.3 mm.
Proper setting
The thread-pulling knife (2) pivots as closely as possible above the hook
and is at the same height as the counter blade (1).
To set the height of the thread-pulling knife:
1. Open the throat plate slide.
2. Loosen the screw (3).
3. Move the thread-pulling knife (2) in such a way that the distance
between the thread-pulling knife (2) and the middle part of the hook
is 0.3 mm.
4. Tighten the screw (3).
WARNING
Risk of injury from sharp and moving parts!
Cutting and crushing possible.
Switch off the machine before setting the thread
cutter.
