the bobbin should be
correctly filled.

Turn screw a (T20) in or out as appropriate.
Adjusting if filling is too high/too low:
• Picture 4 - Turn screw b (T10) in or out as
appropriate.

Incorrectly or unevenly filled bobbins can affect the stitch
quality and impair the functioning of the lower thread
