Thread Shank - Singer C440 Manuel D'instructions

Sewing
3. Adjust the stitch width so that the needle enters the left
hole of button.
4. Check the left and right swing of the needle by turning the
handwheel toward you very slowly, making sure the needle
does not hit the button.
5. Set the number of stitches to sew on the button by
pressing the + and - buttons. Eight stitches is standard.
6. Start to sew at slow speed. The machine will sew the
number of stitches set on the display and then tie off and
stop.
To prevent accidents, make sure that the needle does
not hit the button during sewing, otherwise needle may
break.
7. Raise the foot and cut the threads remaining about 10 cm (4")
long.
8. Pull the thread ends to the wrong side of the fabric with a
hand sewing needle. Tie the threads together to secure.
9. After sewing, move the feed teeth lever to the right. Be
sure to turn the handwheel toward you one full revolution
to re-engage the feed teeth for regular sewing.
NOTE: To sew a 4-hole button, follow the procedure above
for the first two holes. Then lift presser foot slightly and move
fabric to permit stitching the other two holes, either parallel or
criss-cross.
Thread Shank
Buttons on coats and jackets often have a thread shank to
make them stand away from the fabric. Insert a straight pin or
sewing machine needle under the center slit of the foot from
the front, to add space for making the shank. Sew over the pin
or needle. To create a thread shank, pull thread to the back
side of the button and wind the thread around the stitches. Tie
the thread ends securely.
