Setting the lifting gap
Fig. 38: Setting the lifting gap (1)
Always check the width of the lifting gap after making changes to the
needle thread size. The correct width of the lifting gap depends on the
thickness of the needle thread.
Proper setting
The needle thread slides through unobstructed between the nose of the
bobbin case (1) and the slot in the throat plate (2).
To set the lifting gap:
1. Open the throat plate slide.

2. Loosen the screw (4).
3. Turn the eccentric (3) so that the gap between the nose of the bobbin
case (1) and the slot in the throat plate (2) is just large enough to
allow the needle thread to slip through without a problem.
Important
Ensure that the gap is not too big. The middle part of the hook must not
swing back and forth, hitting the slot in the throat plate (2).
4. Tighten the screw (4).
