SINGER 14T968DC Professional 5 Workbook Part 2 - Manual (Page 86)

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 toward 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.
