Turn the machine pulley to align the tip of the shuttle hook with the needle center line. Then loosen the set screw (2) and turn the eccentric shaft (3) to adjust so that the driver needle guard (1) contacts the needle. If the needle contact pressure is too great, skipped stitches may occur. On the other hand, if the driver needle guard (1) is not touching the needle, the tip of the inner shuttle hook will obstruct the needle, resulting in an excessively high amount of friction.

9-5. Adjusting the shuttle race thread guide

1953S

The needle groove of the shuttle race thread guide (1) should be aligned with the center of the needle plate hole, and the needle center and section A should be aligned.

Note

If the shuttle race thread guide is in the wrong position, thread breakages, soiled thread or catching of the thread may occur.
