Singer Patchwork Plus C5950 Instruction Manual page 37

Possible cause:
Bobbin is winding sloppily because thread end not held at beginning of winding process.
Solution:
Before starting to wind, hold the thread tail (coming out of the bobbin) securely, allow the bobbin to partially
fill, then stop to trim the thread tail close to the bobbin.
Fabric Puckers
Possible cause:
Top thread is too tight.
Solution: Reduce top thread tension.
Possible cause: Stitch length is set too short.
Solution: Increase stitch length setting.
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.
Possible cause: Feed teeth lever may have been returned to "up" position, but the handwheel has not yet been turned one full
turn to completely re-engage the feed teeth.
Solution:
The feed teeth need to be raised and re-engaged by turning the handwheel one full revolution.
Possible cause: Stitch length is set at zero.
Solution: Increase stitch length setting.
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.
