Spreader R (1) (at inside sewing position) and spreader L (2) (at outside sewing position) must touch the spreader stoppers (3)
and (4) respectively and stop moving immediately before the needle bar reaches its lowest position.
* Adjustment can be carried out more easily if it is done in manual mode.
1. Tilt back the machine head.
2. Loosen the two screws (5), and then loose the set screw (6).
3. Turn the eccentric pin (7) to adjust.
4. After adjusting, tighten the set screw (6) and the two screws (5) in that order.
NOTE:
Make sure that spreader R (1) and spreader L (2) do not obstruct the needle after adjustment.
