Troubleshooting
If the thread becomes tangled under the
bobbin winder seat
If the bobbin winding starts when the thread is not passed
under the pretension disk of the thread guide correctly, the
thread may become tangled under the bobbin winder seat.
CAUTION
• Do not remove the bobbin winder seat even if the thread
becomes tangled under the bobbin winder seat.
Otherwise, there is a risk of being injured by the cutter of
the bobbin winder seat.
• Do not remove the screw on the bobbin winder guide
post, otherwise the machine may be damaged; you
cannot wind off the thread by removing the screw.
