ADJUSTING BOBBIN WORK THREAD TENSION

After sewing trial stitches and checking the sewing results, adjust the thread tensions if necessary. After adjusting the
tensions, be sure to sew trial stitches again in order to check the sewing results.

■ Adjusting the upper thread tension

We recommend a setting between 6 and 8 for the upper
thread tension.
If utility stitches are being used, refer to "Setting the
Thread Tension" on page 92. If embroidery patterns are
being used, refer to "Adjusting Thread Tension" on
page 301.
■ Adjusting the tension of the bobbin
thread
If the desired stitching cannot be achieved after
adjusting the upper thread tension, adjust the tension of
the bobbin thread. The tension of the bobbin thread can
be adjusted by turning the slotted-head (–) screw on the
bobbin case (gray) for bobbin work.
a Do not turn the phillips screw (+).
b Adjust with a small screwdriver.
To increase the tension of the bobbin thread, turn the
slotted-head (–) screw 30° to 45° clockwise.
To decrease the tension of the bobbin thread, turn the
slotted-head (–) screw 30° to 45° counterclockwise.
ADJUSTING BOBBIN WORK THREAD TENSION
Note
• Turning the screw on the bobbin case (gray)
may push up the spring plate, as shown
below.
If this occurs, gently press down the spring
plate with a screwdriver so it is lower than
the top surface of the bobbin case (gray),
and then insert the bobbin case into the
machine.
a Spring plate
CAUTION
• DO NOT adjust the position of the phillips (+)
screw on the bobbin case (gray) as this may result in
damage to the bobbin case, rendering it useless.
• 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.
Note
• If the bobbin thread tension is tight, the
thread cannot be passed through the
tension spring when the bobbin is installed
in the bobbin case. (Refer to "When tension
is not applied to the bobbin thread" on
page 366.)
