■ Cause
Incorrect lower threading
If the lower thread is incorrectly threaded, instead of
the appropriate tension being applied to the lower
thread, it is pulled through the fabric when the
upper thread is pulled up. For this reason, the thread
is visible from the upper side of the fabric.
■ Remedy
Correctly install the lower thread.
a
Turn off the machine.
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.
