Press .
Note
• With "Embroidery Tension" on the setting
screen, the tension of the upper thread can be
adjusted for embroidering. The selected setting
will be applied to all patterns.
When embroidering, if the overall tension of the
upper thread is too tight or too loose, adjust it
from the setting screen. Press
upper thread tension and press
upper tension. If an individual embroidery pattern
needs additional fine tuning, refer to "Adjusting
thread tension" on page E-26.
Adjusting the bobbin case (with no color on
the screw)
The bobbin case (with no color on the screw) can be adjusted
when bobbin tension changes are required to accommodate
different bobbin threads. See "Embroidery Attractive Finishes"
in the "Basic operations".
To adjust the bobbin tension for embroidery function, using
the bobbin case (with no color on the screw), turn the
slotted-head screw (-) with a screwdriver (small).
1 Do not turn the phillips screw (+).
2 Adjust with a screwdriver (small).
■ Correct tension
Upper thread slightly appears on the wrong side of fabric.
1 Right side
2 Wrong side
■ Bobbin thread is too loose
Bobbin thread appears slightly on the right side of fabric.
1 Right side
2 Wrong side
If this occurs, turn the slotted-head 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
to tighten the
lifting/looping and bobbin thread is not seen on the wrong
to loosen the
side of fabric.
1 Right side
2 Wrong side
If this occurs, turn the slotted-head screw (-)
counterclockwise, being careful not to over-loosen the
screw, approximately 30-45 degrees to decrease bobbin
tension.
• 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-head 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.
