of sewing and starts to form it after it has run a while,
❶
adjust the thread tension guide on the face plate if
the aforementioned trouble cannot be corrected by
adjusting the thread pull-off lever.
1) If the machine fails to form a seam at the
start of sewing, reduce the thread tension by
turning thumb nut ❶ (double nut).
