Balancing Thread Tension
The thread tension should be adjusted depending on
the sewing materials, layers of fabric and sewing
method.
To adjust the thread tension, turn the tension dial.

Balanced tension:
The ideal straight stitch has threads locked between
two layers of fabric.
For an ideal zigzag stitch, the bobbin thread does not
show on the right side of the fabric, and the needle
thread shows slightly on the wrong side of the fabric.
e Needle thread
r Bobbin thread
t Right side of the fabric
y Wrong side of the fabric
Needle thread tension is too tight:
–if the bobbin thread appears on the right side of the
fabric.
Loosen the needle thread tension by moving the dial
to a lower number.
Needle thread tension is too loose:
–if the needle thread appears on the wrong side of
the fabric.
Tighten the needle thread tension by moving the dial
to a higher number.
Raising and Lowering the Presser Foot
The Presser foot lifter raises and lowers the presser
foot.
You can raise the presser foot about 6 mm (1/4")
higher than the normal up position by exerting more
pressure when lifting the presser foot lifter. This
allows for easy removal of the presser foot and helps
you to place thick fabric under the foot.
