Replacing Bobbins
The machine is shipped to you with bobbins in place, ready to
sew. Follow these steps when you need to replace a bobbin.
The bobbins are enclosed in the bobbin cases, which must be
removed in order to replace the bobbin.
Removing the Bobbin Case
1.
Pull the bobbin case latch toward you, and the case
will slide out of the hook assembly.
• On a cylinder bed machine, first open the hinged sewing hook
cover to expose the bobbin case.
Inserting the Bobbin in the Case
1.
Place the bobbin in the case, so that the bobbin rotates clockwise when you pull
the end of the thread.
2.
Guide the thread into the slot on the side of the bobbin case.
3.
Pull the thread under the tension spring and wrap it through the pigtail on the front
of the bobbin case.
4.
Leave several inches of thread hanging from the bobbin case.
5.
Close the sewing hook cover.
Replacing the Bobbin Case
1.
Hold the latch on the bobbin case open, positioning the case on the shaft of the
hook assembly, ensuring that the bobbin remains in place.
2.
Make sure the thread you left hanging is on top.
3.
Release the latch and press the bobbin case into position until you hear a distinct
“click”. If a click is not heard, remove the bobbin case and try again.
CAUTION! Do not attempt to force the bobbin case into the hook
assembly. If resistance is felt, remove the bobbin case, realign the case with
the hook and reinsert it.
Stitch Theory
To fix problems that may occur during sewing, it is important to understand how stitches are
formed. Timing is the relationship between the rotary hook assembly and sewing needle. The
hook and the needle must be in perfect synchronization to have properly formed stitches.
