Adjust the needle thread block
1. Remove taptite, bind B M4X10 (two), and remove the thread hook assy.
2. Set the needle bar to the left base line.
3. Attach a needle.
4. Turn the pulley by hand, and set the needle bar at the highest point (position where the timing shutter base line
faces forward)
5. Loosen the set screw (socket FT 4 x 4).
6. Adjust the height of the needle thread block so that the threading hook passes through the needle hole, and fully
tighten set screw (socket FT 4 x 4).
*Key point
• Slant the needle thread block
slightly to the left (approximately 1 degree) and attach it.
• Adjust so that the upper edge of the threading hook and the upper edge of the needle hole are at the same
height.
NOTE •
If the needle thread block is slanted to far to the left, the hook will not operate, and threading cannot be done
(Fig. 1).
• If the needle thread block is slanted too far to the right, the needle bar supporter assy. and the needle thread
block will come into contact and be damaged (Fig. 2).
7. Attach the thread hook assy. using taptites, bind B M4X10 (two).
Refer to threading usage conditions "1. Outline of Mechanism".
