ADJUSTING
UPPER
THREAD
TENSION
The
correct
stitch
can
usually
be
obtained
by
varying
the
upper
thread
tension.
NOTE
TENSION ADJUSTMENT SHOULD
BE
MADE
WITh
THE
PRESSER
FOOT
DOWN.
To
increase
the
tension,
turn
the
tension
dial
clockwise
(Fig.
20).
To decrease
the
tension, turn the
tension
dial
counter
clockwise
(Fig.
20).
When
the
tension
is
properly
adjusted,
the upper
and
lower
threads
will
cross
in the
center
of
the
material
(Fig.
21-A).
When
the
upper
thread
tension
is
too
tight,
or
the
bobbin
tension
is
too
loose.
the lower
thread
will
lay
flat
along
the
top
of
the material
(Fig.
21-B).
When
the upper
thread
tension
is
too loose
or
the
bobbin
tension
too
tight.
the
upper
thread
will
lay
flat
along
the
bottom
of
the material
(Fig.
21-C).
The
tension
should
be
adjusted little
by little
until
the desired
tension
is obtained.

ADJUSTING
BOBBIN
THREAD
TENSION
1. The
bobbin
thread
tension
on
your
machine
is
correctly
adjusted
before
leaving
the
factory.
Therefore,
it
is
seldom
necessary
to
alter
the
bobbin thread
tension.
Should
it
become
necessary
to
do
so,
the adjusting
screw
of
the
tension
spring
on
the
outside
of
the
bobbin
case
can
be
tightened
or
loosened
to increase
or
decrease the
tension
of
the
bobbin
thread.
2. To increase
the
bobbin
thread tension,
turn
the
adjusting
screw
clockwise.
To
decrease
tension
of
the
bobbin
thread, turn
the
adjusting
screw
counter
Fig.
20
clockwise.
