Adjusting the Thread Tension

SEWING BASICS

■ Setting the stitch width
The stitch width (zigzag width) can be adjusted to make
the stitch wider or narrower.
■ Setting the stitch length
The stitch length can be adjusted to make the stitch
coarser (longer) or finer (shorter).
■ Setting the “L/R Shift”
The placement of the zigzag stitch can be adjusted to
move the stitch to the right or left.
You may need to change the thread tension, depending on the
fabric and thread being used.
■ Correct thread tension
The upper thread and the bobbin thread should cross near
the center of the fabric. Only the upper thread should be
visible from the right side of the fabric, and only the
bobbin thread should be visible from the wrong side of the
fabric.
■ Upper thread is too tight
If the bobbin thread is visible from the right side of the
fabric, the upper thread is too tight. Loosen the thread
tension.
Each touch of makes the thread tension looser.
■ Upper thread is too loose
If the upper thread is visible from the wrong side of the
fabric, the upper thread is too loose. Tighten the thread
tension.
Each touch of makes the thread tension tighter.

Note
• If the bobbin thread was incorrectly threaded, the
upper thread may be too tight. In this case, refer to
“Installing the bobbin” on page 23 and rethread the
bobbin thread.

Note
• If the upper thread is not threaded correctly or the
bobbin is not installed correctly, it may not be
possible to set the correct thread tension. If the
correct thread tension cannot be achieved,
rethread the upper thread and insert the bobbin
correctly.
