SINGER 14T968DC - Manual (Page 9)

Install the Seam Guide Plate. The Seam Guide Plate provides a flat surface for the
fabric and seam guides. It can only be used when the knife and the lower looper
are disengaged. The Seam Guide Plate is used when sewing the Chainstitch,
Cover Stitch and the Triple Cover Stitch.
1. Open looper cover.
2. Remove Knife Cover by pulling it slightly
towards you.
3. Slide the Seam Guide Plate into place.
Disengage Upper Looper. By disengaging the Upper Looper, the looper no longer
moves when sewing. It is nonoperative. If the looper was still engaged, it would hit the
Seam Guide Plate.
1. Turn handwheel until the Upper Looper is in the
highest position.
2. Push the clutch button to the left and up to
disengage.
