Por
ordinary
stitching,
the
tension on
the
upper
.nd
under
threads
should be
equal,
and
just
sufficiently
strong to
lock
both
threads
in
the
cente
of
the
work, an
shown
above (A).
If the
tension
on
the
needle
is
too
tight,
or
if
that
on
the
bobbin
thread
is
too
loose,
the
needle
thread
will
lie
straight
along
the
upper
surface
of
the
material,
thus
mak
ing
an
imperfect
stitch, as
shown
above
8).

A
Correct
stitch
can
usually
be
obtained
by
varying he
trrnsion
cc
the
needle
thread.
All
adjustments
should
be
mode
while
the
presse
foot is
down,
since
the
automotic
release
does
not
permit
adjustments
to
be
mode
while
the
presser
foot
is
up.
To
increase
the
tension,
turn
the
thumb
nut
on
the
tenuion
spring
tcward
you.
To
lessen
the
tension,
turn
the
nut
in
the
opposite
direction.
The
thurnb
nut
ssold
not
be
turned
abruptly,
but
regulated
little
by
little,
unti
the
desired
tension
is
obtained.
The
quality
of
sewing
depends
on
the
thread.
Hence,
it
is
necessary
for
the
user
to
become
fhIy
familiar
with
the
correct
tensions,
through
practice.
