Adjusting the bobbin case lifter
60 Service Instructions M-TYPE DELTA - 00.0 - 12/2019
9.1 Adjusting the lifting gap
Fig. 44: Adjusting the lifting gap (1)
Always check the width of the lifting gap after making changes to the nee-
dle thread size. The correct width of the lifting gap depends on the thick-
ness 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 adjust the lifting gap:
1. Open the throat plate slides ( p. 28).
2. Tilt the machine head ( p. 18).

3. Loosen the screw (4).
4. Push the cover (5) downwards.
5. Loosen the threaded pin (3).
6. Set the bobbin case lifter (6) 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.
