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.
Recommended process:
A. Set the needle into the lower reversal point by turning the hand wheel. Put the stop
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.
B. Remove the scale ( 4) and pull the scale ( 2) onto the bushing ( 3) by turning the hand
wheel.

Loose n screws ( 5), Fig.23 on the ring of the hook ( 4) a nd set the edge to the axe of the
needle (6 ) .
D. Loose n the screw (1 ), Fig. 21 now and move with the needle bar so that the edge of
the hook, which is in the axe of the needle, is placed just above of lower edge of hook
relief (1 ), Fig. 21. Tighten screw (1 ) .
E. Set the edge of the hook in distance of 0.05 - 0.1mm from the hook relief (1 ) at the
