HOW
TO
PREPARE
FOR SEWING
Raise
the
presser
bar.
Hold
end
of
needle
thread
in
the
left
hand loosely
(See
Fig.
13).
Then
with
the right
hand
turn
the
balance
wheel
toward
you
until the
needle
has
moved down
and
up
again
to
its
high
est
position.
In
this
operation
the
needle
thread
will
catch the
bobbin
thread
draw
ing
it
up
through
the
hole
in
the
throat
plate.
With
the
left hand
pull up
the
needle
thread
to
expose
the
bobbin
thread
(See
Fig. 13).
Take
both threads
with
your
hand
and
draw
them,
under
the
presser
foot,
toward
rear
of
machine.
Now
place
material
to
be
sewn
i.incler
presser
foot and
lower
the
presser
foot.
When the
presser
bar
is
in
the
down posi
tion
the
thread
should
extend towards
the
back
of
the
machine,
between
the
toes of
the
presser foot, and
should
be
firmly
held be
tween
the
feed
and the
presser foot.
Once
the
material
and
threads
are
in
position
with
presser
foot lowered
on
to
material,
you
are
ready
to
start the
actual
sewing
operation.
NOTE:
1.
Have
take-up
lever
at
highest
point
before starting
the
sewing
operation.
2.
Do
not
try to
help the
feeding
of
the
work by
pulling
the
ma
terial as
this may deflect
the
needle
and cause
it
to
break.
The machine
feeds without
as
sistance.
3.
After
threading,
NEVER
run
machine
without
material
be
tween
presser
foot
and
feed
