Fabric Is Caught In The Machine And Cannot Be Removed - Brother 888-M20 Operation Manual

Troubleshooting
<With symptoms 3 and 5 described above>
The upper threading is incorrect.
Return the thread tension dial to "4", and then refer to
"Tangled thread on wrong side of fabric" on page 79 to
correct the upper threading.
 Cause 2
A needle and thread appropriate for the fabric are not
being used.
The machine needle that should be used depends on the
type of fabric sewn and the thread thickness.
If a needle and thread appropriate for the fabric are not
being used, the thread tension will not be adjusted
correctly, causing wrinkles in the fabric or skipped
stitches.
• Refer to "Fabric/Thread/Needle Combinations" on
page 21 to check that a needle and thread
appropriate for the fabric are being used.
 Cause 3
An appropriate upper tension is not selected.
Select an appropriate thread tension.
Refer to "Adjusting the thread tension" on page 29.
The appropriate thread tension differs depending on the
type of fabric and thread being used.
* Adjust the thread tension while test sewing on a
piece of scrap fabric that is the same as that used in
your project.
Note
• If the upper threading and bobbin threading are
incorrect, the thread tension cannot be adjusted
correctly. Check the upper threading and bobbin
threading first, and then adjust the thread tension.
• If the bobbin thread is visible from the right side of
the fabric
Turn the thread tension dial counterclockwise to
loosen the upper thread tension.
• If the upper thread is visible from the wrong side of
the fabric
Turn the thread tension dial clockwise to tighten the
upper thread tension.
