⑴ Fixing the height of the needle bar

Figure 37 to make sure that the needle bar carved sign ⓐ meets the end ⓑ of the frame, then tighten the screw.

⑵ Adjusting the timing of hook edge and needle center crossing
First, set the stitch length at “0”. Adjust the hook gear clamp screw ① in Figure 39 so that the hook edge fall exactly at
the center of the needle center when the needle bar is raised 2.4 mm from its lowest position as in Figure 38. When this is
done, the hook edge will be placed at about 1.5 mm above from the front of the needle thread hole.
