B. Adjusting the link stopper screw
ⓐ When the needle is at its lowest position, push the trimmer driving link in the arrow (
) direction within the
moving range of the trimmer cam. Check if there is enough room between the trimming cam roller and both ends
of the trimmer cam.
ⓑ With the trimming cam roller inserted into the moving range of the trimmer cam, adjust the end of the link
stopper screw to touch the trimmer connecting bar. Then tighten the nut afterwards.

If there is an insufficient clearance between the trimming cam roller and both ends of the trimmer cam, trimming may
not perform correctly, or the machine could be jammed at the beginning or at the end of sewing or trimming.
[Caution]
If the positioning is not correct, returning to the previous position after trimming could be delayed, and the first stitch
may not be tight enough.
