SEWING
IN
REVERSE
When
you wish
to
sew
backward
to
tie
the
threads
at
the
beginning
or
end of
a
seam,
press in
the
button
R,11,
Fig.
1,
as
far
down as
it
will
go.
The
machine
will
sew
backward
as
long
as
the
button is
held down.
ADJUSTING
THE
TENSIONS
Always
adjust the
upper
tension
with the
presser
foot
down, as
the tension
is
released
when
it
is
raised.
To
increase
the
tension
on
the
upper
thread, turn
dial
(Fig.
13)
to
the
right.
To
decrease,
turn
to
the
left..
b
Before
adjusting
lower
tension
be
sure
that the
machine
is
threaded
properly. When
necessary
to
change
the
bobbin ten
sion, turn
small
screw
(Fig.
14)
on
side
of
the
bobbin
case
—
clockwise
to
tighten,
counterclockwise
to
loosen.
When
the
upper
tensions
are
properly
balanced,
a
perfect
stitch will
be
formed
with both
threads
interlocking
in
fabric
(Fig.
15).
When the
upper
tension is
too
tight,
the
lower
thread is
pulled
up
over
the
upper
thread
which is lying
flat
on
the
fabric
(Fig.
16).
When the
upper
tension
is
too
loose,
the
upper
thread
forms loops over
the
lower
thread lying
flat
on
the
fabric

order
to
move

release
the

completely by
pressing
down
on
the

which
drops
the

the
needle plate.
To
return
feed
to

return
knob
to
“HI”.
PREPARING
TO
SEW
Have
take-up
lever
at
highest point
before
starting
to sew.
Do
not
try
to
help
the
feeding
by
pulling the
material as
this
may
deflect
the
needle
and
cause
it
to
break.
NEVER run
machine without material under
the
presser foot.
Place
material
and
threads
in
position under
the
presser
foot
and
lower
foot.,
Turn
the
hand
wheel toward
you
until
the
needle
is
at its
highest
point.
You
are
now
ready
to begin sewing. By having the
needle
at
its
highest point,
it
is
not
necessary
to
touch
the
hand
wheel
to
start
the
machine.
You
merely press
the
control. The
speed
of
the
machine is
regulated
by
increasing or
decreasing
the
amount of
pressi.re
exerted
on
the
control.

REMOVING THE
WORK
Be
sure
to
stop the
machine
when
the
thread
take-up
lever
and

are at
the
highest position.
Now raise
the presser
foot
and
draw
the fabric
back
and
to
the
left,
Figs.21-A
and
B, and
pass
the threads
over the
thread
cutter.
Pull down
slightly,
holding
thread in
both
hands, so
as not
to bend
the
needle.
Leave
the ends
of thread
under
the presser
foot.
