needle eye must be 0 to 0.1mm.

2. Attach the size 75/11 needle.
3. Turn the pulley by hand and move the needle to its highest point.
4. Loosen the screw (set screw socket (FT) M4 x 4) of the needle thread block with the hex wrench (2mm).
5. Move the needle thread block up and down, to adjust the clearance between the top edge of the hook and the top
edge of the needle eye to 0 to 0.1mm. After that, tighten the screw (set screw socket (FT) M4 x 4) of the needle
thread block.
