Correct
tension
is
Important
because
too
much
or
too
little
will
weaken
your
seams
or
cause
your
fabric
to
pucker.
Make
a
test
sample
with
the
fabric
and
thread
you
plan
to
use,
and
ex-
amine
it,
A
perfect
stitch
'
au
II
have
the
needle
and
bobbin
threads
locked
between
the
two
layers
of
fabric
with
no
loops
on
top
or
bottom
and no puckers,
Needle-Thread Tension
The
tension
dial
regulates
the
degree
of
ten
sion
on
your
needle
thread.
Set
it
according
to
the
type
of
thread
and
fabric
you
use.
The
numbers
on
the
dial
eliminate
guesswork
in
duplicating settings.
If
the
stitches
in
your
test
sample
look
loose,
increase
needledhread
tension.
If
the
fabric
puckers, decrease tension.
• To Increase tension, turn dial to higher num
ber.
♦ To decrease tension, turn dial to lower num
ber.
Bobbin^Thread Tension
Bobbin-thread
tension
Is
controlled
by
a
screw
located
on
the
bobbin
case.
You
will
seldom
need
to
adjust
bobbin-thread
tension
since
it
is
usually
possible
to
obtain
the
correct
bal
ance
by
adjusting
needle-thread
tension
alone.
On
those
rare
occasions
when
It
becomes
necessary
to
adjust
the
bobbin-thread
ten
sion,
use
the
small
tension
screwdriver
fur
nished
with
your
accessories.
A
very
slight
turn
on
the
screw
nearest
the
thread
slot
on
the
bobbin
case
will
produce
a
noticeable
change in bobbin-thread tension.
• To Increase tension, turn screw clockwise.
• To decrease tension, turn screw counter
clockwise.
