Lower threading
Install the bobbin wound with thread.
CAUTION
1Prepare the bobbin wound properly
before threading the lower thread.
• See page 11 for the details about bobbin
winding.
2Raise the needle by turning the
handwheel toward you
(counterclockwise) and raise the presser
foot lever.
3Remove the bobbin cover by sliding it and
lift toward you.

4Put the bobbin in so the thread comes out
in the direction shown by the arrow.
CAUTION
5Hold the end of the thread, push the
bobbin down with your finger, and then
pass the thread through the slit, as shown.
• If the thread is not correctly inserted through
the tension-adjusting spring of the bobbin
case, it may cause incorrect thread tension.

• Make sure that the end of the thread comes
out from the cover toward the rear of the
machine (as shown in the illustration).
• Draw up the lower thread before starting
sewing. Refer to “Drawing up the lower
thread” on page16 after threading the upper
thread.
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.
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.
