Bobbin thread
■
Cause
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.
■
Remedy/check details
Correctly install the bobbin thread.
a
Press
, and raise the presser foot lever.
b
Remove the bobbin from the bobbin case.
c
Place the bobbin in the bobbin case so that the thread
unwinds in the correct direction.
• Hold the bobbin with your right hand with the thread
unwinding to the left, and hold the end of the thread
with your left hand.
Then, with your right hand, place the bobbin in the
bobbin case.
If the bobbin is inserted with the thread unwinding in
the wrong direction, sewing will be done with an
incorrect thread tension.

While holding the bobbin in place with your finger,
pass the thread through the slit in the needle plate
cover.
• Hold down the bobbin with your right hand, and
then pull the end of the thread around the tab with
