Fabric Puckers
Possible cause:
Top thread is too tight.
Solution:
Reduce top thread tension.
Possible cause:
Wrong style needle for fabric type.
Solution:
Use correct needle style and size for your fabric.
Fabric Is Tunneling Under Stitches
Possible cause:
Fabric is not properly stabilized for the density of the stitches (for example, satin stitch applique).
Solution:
Add a fabric stabilizer underneath the fabric to help keep the stitches from tunneling in together, forming a
puckered ridge in fabric.
Loud Noise When Sewing
Possible cause:
Thread not in take-up lever.
Solution:
Rethread the machine, making sure the take up lever is in its highest position so thread goes in the eye of the take
up lever — turn machine hand wheel toward you to raise the take up lever to its highest position for threading.
Possible cause:
Thread path is obstructed.
Solution:
Check that thread is not caught on the thread spool or behind the spool cap.
Machine is Not Feeding Fabric
Possible cause:
Presser foot lifter has not been lowered onto fabric after threading.
Solution:
Lower the presser foot lifter before starting to sew. Don´t "push" or "pull" the fabric as you sew.
Machine Will Not Run
Possible cause:
Bobbin winding spindle is engaged when you try to sew.
Solution:
Disengage bobbin winding spindle by pushing it to the left.
Possible cause:
Power cord and/or foot control not plugged in correctly.
Solution:
Make sure power cord/foot control are correctly seated in machine and power supply.
Possible cause:
Wrong bobbins being used.
Solution:
Use bobbins that are the same style as those that come with the machine (SINGER® Class 15 transparent
bobbins)– don't substitute.
Needles Breaking
Possible cause:
Bent, dull or damaged needle.
Solution:
Discard needle, insert new needle.
Possible cause:
Wrong size needle for fabric.
Solution:
Insert appropriate needle for fabric type.
Possible cause:
Machine not threaded correctly.
Solution:
Rethread the machine completely.
Possible cause:
"Pushing" or "pulling" fabric.
Solution:
Don't manually push/pull fabric in order to sew, but allow the machine's feed teeth to draw fabric under the
presser foot as you guide it.
