Needle thread tension
To get perfect sewing results, the needle
and bobbin thread tensions must be
perfectly tuned to each other. The normal
setting for utility stitches is in the range
of 4-5.
Check the tension with a wide zigzag
stitch. The threads must be interlaced
between the two fabric pieces.
If the needle thread tension is too high the
threadsareinterlacedabovethetopfabric.
If the needle thread tension is too low, the
threads are interlaced below the lower
fabric.
The adjustment of the needle thread
tension is described on page 22.
Topstitching
StraightstitchGcanbesewnusingany
of15variousneedlepositionsinsucha
way that you can always guide the sewing
foot along the fabric edge for top-stitching
work. The top-stitch needle position is
determined by the needle position dial.
If you wish to top-stitch farther from the
fabric edge, simply guide the fabric along
the guide marks on the needle plate or use
theedgeguide(standardaccessoryNo.8).
