Thread
tension
Thread
cutters
The
notch
on
the
back
of
the
presser
bar
is
the
thread
cutter.
Threads
can
easily
be cut
off
when
you
have
finished
sewing.
There
is also
an
additional
thread
cutter
for
use
when
bobbin
winding
and
one
for
cutting
the
bobbin
thread
after
insertion
of
the
bobbin
case.
See
page
10
and
11.
Tension
of
the
upper
thread
The
dial
which
regulates
the
tension
of
the
upper
thread
is
graduated
from
0—10.
The
higher
the
number,
the
tighter
the
tension.
Normal
thread
tension
is
obtained
by
setting
the
dial
within
the
white
area.
The
thread
reel
supplied
with
the
machine
contains
synthetic
thread
with
which
your
machine
has
been
tested.
If
using
a
coarser
thread,
it
may
be
necessary
to
alter
the
thread
tension
slightly.
As
a
general
rule
the
thread
tension
should
be
increased
by
two
grades
on
the
dial
when
sewing
with
cotton
thread.
The
type
of
fabric
may
also
require
some
adjustment
in
the
tension.
When
sewing
buttonholes
and
decorative
stitches
the
thread
tension
is
decreased
automatically.
When
return
ing
to
regular
sewing
the
normal
thread
tension
is
set
again.
