Thread Tension Settings
Set the thread tension to suit the type of fabric and thread used.
As the number on the thread tension discs increases, the thread
tension becomes tighter. See the stitch table on pages 28-31 for
thread tension recommendations for each stitch.
Correct Thread Tension
Lower looper thread and upper looper thread should be well bal-
anced with the same tension (both looper threads should cross at
the edge of the fabrics). Needle threads should not be too loose
or too tight, but equally balanced tension.
Upper Looper Thread Is Too Loose (A)
The upper looper thread is unbalanced when it is pulled to the
wrong side of the fabric. Tighten the thread tension of the up-
per looper or loosen the thread tension of the lower looper.
Upper Looper Thread is Too Tight (B)
The upper looper thread is unbalanced when it is pulling on the
right side of the fabric. Loosen the thread tension of the upper
looper or tighten the thread tension of the lower looper.
Lower Looper Thread is Too Loose (C)
The lower looper thread is unbalanced when it is pulled to the
right side of the fabric. Tighten the thread tension of the lower
looper or loosen the thread tension of the upper looper.
Lower Looper Thread is Too Tight (D)
The lower looper thread is unbalanced when it is pulling on the
wrong side of the fabric. Loosen the thread tension of the lower
looper or tighten the thread tension of the upper looper.
Left Needle Thread Is Too Loose (E)
If the left needle thread is too loose, tighten the thread tension
of the left needle or loosen both looper threads.
Left Needle Thread is Too Tight (F)
If the left needle thread is too tight, loosen the thread tension of
the left needle.
Right Needle Thread is Too Loose (G)
If the right needle thread is too loose, tighten the thread tension
of the right needle.
Right Needle Thread is Too Tight (H)
If the right needle thread is too tight, loosen the thread tension
of the right needle.
