Remove the tangled thread. When
the bobbin case is plugged up, clean
the hook area.
Adjust the tension of the upper
thread.
Stretch the fabric properly in the
embroidery hoop.
Always use stabilizer material for
embroidery with stretch fabrics, thin
fabrics, fabrics with a loose weave
and fabrics where stitches easily con-
tract.
If the embroidery arm or embroidery
hoop bumps into objects, the designs
will be distoreted. Do not place
objects within the range of any
embroidery hoop motion.
Stretch the fabric on the hoop once
again so that the material coming out
of the embroidery hoop does not
cause problems, rotate the design
and embroider.
If embroidery is done with the fabric
hanging off the table, the embroidery
module movement will be affected.
Support the fabric while embroider-
ing.
Stop the sewing machine and arrange
the fabric correctly.
If the arm is moved during the pro-
cess, the design may be distorted.
Be careful when removing or attach-
ing the embroidery hoop.
