Adjusting the Bobbin Case (with No Color
on the Screw)
The bobbin case (with no color on the screw) can be
easily adjusted when bobbin tension changes are
required to accommodate different bobbin threads.
Refer to “Embroidering Attractive Finishes” on page 62.
To adjust the bobbin tension for embroidery function,
using the bobbin case (with no color on the screw), turn
the slotted screw (-) with a (small) screwdriver.
1 Do not turn a phillips screw (+).
2 Adjust with a screwdriver (small).
■ Correct Tension
Upper thread slightly appears on the wrong side of fabric.
■ Bobbin Thread Is Too Loose
Bobbin thread appears slightly on the right side of fabric.
If this occurs, turn the slotted screw (-) clockwise, being
careful not to over-tighten the screw, approximately 30-45
degrees to increase bobbin tension.
■ Bobbin Thread Is Too Tight
Upper thread on the right side of fabric seems to be lifting/
looping and bobbin thread is not seen on the wrong side
of fabric.
If this occurs, turn the slotted screw (-) counterclockwise,
being careful not to over-loosen the screw, approximately
30-45 degrees to decrease bobbin tension.

CAUTION
• When adjusting the bobbin case, be sure to
remove the bobbin from the bobbin case.
• DO NOT adjust the position of the phillips (+)
screw on the bobbin case as this may result in
damage to the bobbin case, rendering it
unusable.
• If the slotted screw (-) is difficult to turn, do
not use force. Turning the screw too much or
providing force in either (rotational) direction
may cause damage to the bobbin case. Should
damage occur, the bobbin case may not
maintain proper tension.
