2. B. ADJUSTMENT OF NEEDLE AND HOOK: ROTARY HOOK (RH)
The hook in connection with the needle must be set so that the edge is in the position of
lower relief of needle when the hook is taking the loop of upper thread. Figure 19,21,22,23.

sleeve ( 2) on needle bar and insert the scale ( 4) between stop sleeve and bushing ( 3),
Figure 19. Tighten the screw ( 5) so that there is no play between the bushing, stop
sleeve and scale. The thickness of the scale for rotary hook is 2mm for medium and
2.5mm for heavy materials.
