Adjusting Thread Tension - Singer 5040 Instruction Manual

Adjusting thread tension

(For straight stitching)
A perfect, well balanced stitch (1), will have
the needle and bobbin threads locked
between the two layers of fabric with no loops
on top or bottom and no puckering.
Too much tension will produce a tight stitch
(2) which will cause the fabric to pucker.
• To decrease tension, turn the dial to a lower
number.
Too little tension will produce a loose stitch
(3) which will cause loops in your seam.
• To increase tension, turn the dial to a higher
number.
Adjusting thread tension
(For zig zag stitching)
The correct tension setting will produce a
smooth even stitch (1).
Too much tension will produce a tight stitch
(2), causing fabric to pucker. Loosen tension
by turning dial to a lower number.
Too little tension will produce a loose stitch
(3), causing loops in your pattern. Tighten
tension by turning dial to a higher number.
