Adjusting Needle Swing
If the needle swing when it is still in the fabric, correct it as follows.
<TO ADJUST>
1 Remove the front cover (see page 3).
2 Select the zigzag stitch ( ) and set the stitch width dial at 5.
3 Loosen the setscrews on the worm.
4 While holding the worm as not to rotate, turn the handwheel to adjust the needle bar swing
so that the needle starts to swing 2 - 3 mm above the needle plate in the right outflow.
5 Tighten the setscrews on the worm securely.
6 Attach the front cover.
NOTE:
The upper shaft should turn smoothly without an excessive backlash between the worm
and gear.
