Adjusting the Bobbin Tension
1.
Turn the screw on the bobbin case
clockwise
to
tighten
bobbin
tension.
2.
Turn the screw on the bobbin case
counterclockwise
to
loosen
the
bobbin tension.
Once the tensions have been adjusted for
the type of thread you plan to use, only
minor changes will be needed as the
fabric, letter size, and alphabet style
changes.
Take-Up Spring Adjustment
Located behind each upper plastic tension disc is a hook spring called the tension take-up
spring. The tension take-up spring picks up the excess slack on the thread while the machine
is sewing. This is particularly important when the machine is sewing small letters. The
take-up spring may require adjustment for two reasons.
Fabric
Change
You may find it necessary to adjust the tension take-up spring when
you switch to very thin or very thick fabric. To sew on thinner
fabric, lighten the tension on the take-up spring. To sew on thicker
fabric, tighten the tension. Follow the steps listed below for
adjusting the take-up spring tension.
False Thread
Break Detection
There may be a time when you notice that the machine is constantly
detecting thread breaks. The machine keeps stopping, but the thread
is not broken. When this occurs, the tension take-up spring is too
tight.
