Remove the bobbin.
l
Pull the thread through the guide slit in the
bobbin winder seat to cut the thread with
the cutter.
■ 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.
Note
• When removing the bobbin, do not pull on
the bobbin winder seat. Doing so could
loosen or remove the bobbin winder seat,
resulting in damage to the bobbin winder.
CAUTION
• Check that the bobbin
thread has been wound
correctly, otherwise the
needle may break or the
thread tension will be
incorrect.
• Be sure to clean the bobbin case each time
that the bobbin is changed. Thread wax and
dust easily collect around the hole in the
tension-adjusting spring on the bobbin case,
resulting in an incorrect thread tension. For
details, refer to “Cleaning the bobbin case” on
page 286.
• Be sure to check the tension of the bobbin
thread each time that the bobbin is changed.
• Depending on the bobbin thread type, the
tension of the bobbin thread may differ. Be
sure to check the tension of the bobbin thread
and adjust the tension if necessary.
For a metal bobbin, use both weights, large (L)
and small (S).
For detailed instructions on how to adjust the
bobbin tension, refer to page 124.
1 Weight (L) (Part Code: XC5974-151)
2 Weight (S) (Part Code: XC6631-051)
