When the zigzag width is set at maximum, the needle
should fall evenly into the both sides of needle plate hole (
the distance needle and edge of hole at each side). (fig.

1. Set the pattern number at “4” and stitch width to 5.
2. Remove the presser foot and the light cover.
3. Loosen the screw (a) located on the top of the needle
bar guide assembly. (fig. 5-2)
By slightly moving the needle bar left or right, adjust
the needle position so that the needle falls evenly into
the hole.
4. Tighten the screw (a) and re-check the position of
