ADJUSTING
TOP THREAD
TENSIONS
Probably
the most
important
control
on
your
machine
is this
one that
regulates
your top thread tension.
There
are many
reasons for
having
to
reset your
tension.
The best tension
for
one fabric may not be correct
for another.
The required
tension
depends
upon the
stiffness
of the
fabric,
thickness
of the
fabric,
numbers
of layers of fabric
being
se,wn, as well as the type of stitch
you are
making.
It is best to test the stitching
on a scrap
of the fabric you are using before starting
to make a garment.
Use the straight
stitch
function
as shown at the right.

but the seam

it may be necessary to loosen
the tension
on both
the top and bottom
threads.
Be sure to balance them.
When adjusting
the tension
on the bobbin

make
slight
adjustments
