Helpful Tips:
When embroidering larger or heavier pieces of fabric,
it is helpful to support the fabric on a table in front and
back of the machine.
When working with specialty threads (such as metallic
threads) or designs with dense stitch areas, it is
recommended that you lower the embroidery speed.
Be sure to deactivate the Thread Cutter Mode when
doing endless embroidery. This will help eliminate the
possibility of the thread coming out of the needle when
sewing the alignment stitches and long jump stitches.
To change a bobbin during embroidery, raise the
needle by turning the handwheel toward you. Raise the
presser foot lifter. Remove the hoop from the machine
with the fabric remaining in the hoop. Remove the
bobbin cover plate and empty bobbin. Wind the bobbin,
insert it into the bobbin case and replace the bobbin
cover plate. Place the hoop back onto the machine.
Lower the presser foot lifter. Press the Start/Stop
button to resume embroidery.
Should you find that the hoop will not release from
the machine because the back of the foot is coming
in contact with the endless hoop clamp, use Reverse/
Forward Stitch button to move to another area that will
allow you to remove the hoop. When the bobbin has
been changed, use Forward/Reverse Stitch button to
move the needle back to position and resume sewing.
If this is not possible, due to the type of design you
are embroidering, remove the presser foot and needle
to remove the hoop from the machine. Replace the
presser foot and needle to resume embroidering.
