TEXI Tutu operation manual
SEWING HEAVY FABRIC
When sewing heavy fabrics, the toe end of presser foot tends to lift up
and sewing can not be started smoothly. In such case, place a piece of
cardboard or fabric of same thickness under the heel end of the presser
foot.
* The presser foot lifter can be raised 1 step higher for placing heavy
materials under the presser foot easily.
A: Fabric B: Thick paper or fabric
SEWING OVER OVERLAPPED AREAS
Guide the fabric with your hand when sewing over overlapped areas.
ADJUSTING THE THREAD TENSIONS
The thread tension must be properly balanced. If adjustment is required, it can be made by changing the upper
thread tension.
A. Correct Thread Tension
Upper and bobbin threads should lock
approximately in the middle of fabric.
C. When upper thread appears on the bottom
side of fabric.
Turn the tension dial to a higher number.
Helpful Hint
Like shown on drawing, stitches on top side of fabric are good but bottom side
tends to have a bunch of thread, it usually means that the upper thread is not
threaded correctly (especially threading of the upper thread tension regulator
may not be correct).
CAUTION: The feed dog will feed the fabric automatically.
Do not pull nor press on fabric with hands. It will cause needle breakages
or poor quality stitches.
B. When bobbin thread appears on top side of fabric.
Turn the tension dial to a lower number.
D. Thread Tension for Zigzag Stitches
To sew zigzag stitches, the thread tension should
be set to a slightly weaker tension than when sewing
straight stitches. You will obtain a nicer stitch when
upper thread appears on bottom side of fabric.
