Then remove the rubber plug (2), loosen the screw (3) and then move the needle bar up or down to adjust so that the second reference line from the bottom of the needle bar (reference line A) is aligned with the lower edge of the needle bar bush (1).

* If using a DP X 5 needle, use the highest reference line (reference line a).

1.Turn the pulley (1) in the direction of the arrow to raise the needle bar from the lowest position until the lowest reference line on the needle bar (reference line B) is aligned with the lower edge of the needle bar bush (2).

*If using a DP X 5 needle, align with reference line b which is the second reference line from the top.

2.Loosen the bolt (3).

3.Move the driver (4) sideways so that the rotary hook tip is aligned with the middle of the needle, and then move the driver

(4) back and forth so that it is touching the needle. Then tighten the bolt (3).

NOTE:

If the driver (4) crosses the needle more than necessary, it will cause problems with the thread tension. Furthermore, if it does not cross the needle, skipped stitches or needle breakages may occur.
