Lower threading

Install the bobbin wound with thread.
• For more details on using the quick-set
bobbin, see page 14.
CAUTION
●
Make sure you turn off the machine
while threading. If you accidentally step
on the foot controller and the machine
starts to sew, you could be injured.
Prepare the bobbin wound properly

before threading the lower thread.
• See page 11 for the details about bobbin
winding.
Raise the needle by turning the handwheel

Make sure you set the bobbin so the
thread unrolls in the right direction. If
the thread unrolls in the wrong direction,
it may cause the thread tension to be
incorrect or break the needle.
