Adjusting Top Thread Tension; Changing Presser Foot - Singer 7258 Instruction Manual

ADJUSTING TOP THREAD TENSION
90% of your sewing will be done with the tension control dial (on
top of the machine) set at "AUTO".
IHelpfulHint: A slight adjustment to a higher number or a l
lower number may improve sewing appearance.
STRAIGHT STITCHING
The correct appearance of your stitching is largely determined
by the balanced tension of both top and bobbin threads. The
tension is well balanced when these two threads 'lock' in the
middle of layers of the fabric you are sewing.
If, when you start to sew, you find that the stitching is irregular,
you will need to adjust the tension control.
Make any adjustments with presser foot 'down'.
A balanced tension (identical stitches both top and bottom) is
usually only desirable for straight stitch sewing.
ZIG ZAG and DECORATIVE SEWING
For zigzag sewing and decorative stitch functions, thread ten-
sion should be less than for straight stitch sewing.
You will always obtain a nicer stitch and less puckering when
the upper thread appears on the bottom side of your fabric.
BOBBIN TENSION
The bobbin tension has been correctly set at the factory,
so you do not need to adjust it.
