Press "Bobbin" key. The machine will set the zigzag

5. Turn the handwheel toward you until the tip of the
hook comes behind the test pin.
6. Loosen the setscrew (use an Allen wrench of 2 mm
width across flats) and move the needle bar supporter
in the direction of the red arrow so the test pin just
touch the tip of the hook. Tighten the setscrew.
7. Attach the bobbin holder and the needle plate. Check
the needle drop position. The needle drops in the
center of the needle plate hole as shown.
If the clearances A and B are not even, adjust the needle
drop position first and then adjust the clearance between
