Incorrect bobbin threading
If the bobbin thread is incorrectly threaded, instead of the
appropriate tension being applied to the bobbin thread, it
is pulled through the fabric when the upper thread is
pulled up. For this reason, the thread is visible from the
right side of the fabric.
Correctly install the bobbin thread. (page 34)
* The thread becomes tangled on the wrong side of
the fabric.
* After starting sewing, a rattling noise is made and
sewing cannot continue.
* Looking under the fabric, there is tangled thread in
the bobbin case.
Incorrect upper threading
If the upper thread is incorrectly threaded, the upper
thread passed through the fabric cannot be firmly pulled
up and the upper thread becomes tangled in the bobbin
case, causing a rattling noise.
Remove the tangled thread, and then correct the upper
threading.
Remove the tangled thread. If it cannot be removed,
cut the thread with scissors.
* Refer to "Cleaning the Race" on page 181.
Remove the upper thread from the machine.
Correct the upper threading by following the
instructions in "Upper Threading" on page 36.
* If the bobbin was removed from the bobbin case,
refer to "Setting the Bobbin" on page 34 to correctly
install the bobbin.
