ADJUSTING
TOP
THREAD
TENSION
STRAIGHT
STITCHING
The
quality
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
fabric you
are
sewing.
Set
the
tension
control
at
the
AUTO
position
or
3
for
normal
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.
ZIGZAG
STITCHING
The
top
thread
may
appear
on the
bottom
depending
on
the
thread,
fabric,
type
of
stitch
and
sewing
speed,
but
the
bobbin
thread
should
never
appear
on the
top
of
the fabric.
