SINGER 14T957DC - Manual (Page 10)

Slip the thread into the center slot next to the take-up lever, then into the center
slot in the guides just above the needle clamp. Next slip the thread behind the
metal guide and then into the eye of the needle in A position, and then under
what looks like a bridge at the back of the foot. Pull the thread tail to the back
of the serger.
THREAD TIPS FOR 4-THREAD ULTRA STRETCH SAFETY STITCH
• Be sure to follow the threading sequence outlined above.
• Make sure needles are set-up in positions A and B for the 4-thread Ultra
Stretch Safety Stitch. This is very well illustrated in your manual on page
15.
• When inserting the needle in positions A & B, loosening both needle
screws A and B will facilitate inserting and removing needles.
• The Brown Chain/Cover Stitch looper is not used for the 4-Thread Ultra
Stretch Safety Stitch.
• Always reset the tension dials by re-selecting the stitch after threading the
serger.
