CAUTION
• Check that the bobbin thread has been wound
correctly, otherwise the needle may break or
the thread tension will be incorrect.

that the bobbin is changed. For details, refer to
"Cleaning the bobbin case" on page 175.
• Be sure to check the tension of the bobbin
thread each time that the bobbin is changed.

■ If bobbin winding is stopped before it is
finished
The bobbin winder stops automatically if the thread does
not feed, for example, if it becomes tangled on the spool
pin. If this occurs, correctly thread the bobbin winder, and
then wind the bobbin correctly.
