Operation Manual

To
protect
presser
foot
and feed,
never
operate
machine
without
placing
fabric
under the
presser
foot.
With
the
cloth
inserted
and the
presser
foot
lowered,
turn
the balance
wheel
toward
you.
At the
same
time,
give
a
slight
pressure
with
your knee
against
the knee
control—or
against
the foot
control
on
some
portable
models.
7.
To
remove
the
work
Stop the
machine.
Turn the
balance
wheel
toward
you
until
the take-up
(see section
on
threading
the needle)
is
at its highest
point.
(Or
turn the
wheel
to
complete
the
stitch.)
Raise
presser
foot. (On
lifting
the, presser
foot,
the
tension
is
automatically
released.)
Draw
the
cloth
to
the rear
of the
needle.
Cut the
thread
close to
the
material
on the thread
cutter.
8.
To regulate
the
tension of
the
upper
thread
The
tension
of the upper
thread
is regulated
by
means
of tension
nut
(M),
(Fig.
4).
Turning
this
screw
clockwise,
the
tension
will become
tighter.
Unscrewing
it,
counter
clockwise,
it will
become
looser.
Having
adjusted
the
tension
for
a
certain
kind
of
thread,
(you
con
best
judge
this
tension
for
yourself
by
pulling
the thread
gently
with
your
hand
when you
have
threaded
the
machine
through
the tension
spring),
lust
glance
at
the number
marked
in the bell
behind
the ten
sion
nut, and
note its
relative
position.
If
the
upper tension
is
too loose,
the under
thread
will
pull
down
the
upper
thread,
forming
little
knots or
loops
as shown
in Fig.
8.
If
the upper
tension
is too
tight,
the
under
thread
is
drawn
up,
as
illustrated
in Fig.
9 Fig.

shows
the locking
in
the
two threads
in
the
center
of
the
material,
as a
result
of the
proper
adjustment
of
both
tensions.
If the
tension
is
too
loose,
take
the
bobbin
case
out
of
the
machine
(Fig.
5),
and tighten
the
small
tension
screw
(Z)
in a
clockwise
direction
with
the
aid
of
the
screw
driver.
If
the
tension
is too
tight,
unscrew
it
in
a
counter
clockwise
direction.
(Fig.
11).
10. To
regulate
the
length
of stitch
The
length of
the
stitches
is
regulated
by
the
stitch
regulator
screw.
(Fig.
6). In
the
zero—(or
neutral)—
posi
tion,
there
is
no
feeding
at
all.
The
numbers
above
zero
ore
for
forward
stitching;
the space
below
for
reverse
stitching.
