Lower threading
Install the bobbin wound with thread.
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

●
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.

thread" on page 16 after threading the upper
thread.
