To
draw
up
the
under
thread
and
to
commence
sewing
Hold
the
end
of
the
upper
thread
and
turn
the
balance
wheel
with
your
hand
in
the
direction
of
the
arrow,
until
the
needle
goes
down
once
and
up
again.
The
under
thread
will
then
come
up
in
the
shape
of
a
loop
through
the
needle
hole
and
is
to
be
drawn
up
completely,
by
passing
a
screw
driver
or
a
pair
of
scissors
between
the
presser
foot
and
the
needle
plate
in
the
direction
of
the
forward
feeding.
Now
place
the
upper
thread
under
the
presser
foot
by
the
side
of
the
under
thread.
Then
the
presser
foot
is
lowered
ond
the
thread
ends
are
held
behind
the
presser
foot,
until
some
stitches
ore
formed.
Do
not
forget
this
to
prevent
the
upper
thread
from
being
jammed
in
the
shuttle
race.
To
protect
the
press.er
foot
ond
the
feed
dog,
never
run
the
machine
without
having
a
piece
of
fabric
inserted.
Regulation
of
the
tension
of
the
upper
thread
is
effected
with
the
aid
of
tension
nut
M
(fig.
4).
Giving
this
screw
a
few
turns
,
the
tension
will
be
tighter,
and
turned
in
the
opposite
direction
looser.
If
machine
is
set
for
right
tension
and
a
certain
grade
of
thread,
note
the
proper
figure
on
the
bell
that
is
attached
behind
the
nut,
in
its
position
to
the
divisions,
stamped
on
the
disconnecting
sleeve
in
the
bell.
After
a
certain
practice
is
obtained,
one
can
get
along
without
these
figures
and
divisions,
of
course.
If
the
upper
tension
is
too
loose,
then
the
shuttle
thread
will
draw
down
the
upper
thread,
thus
forming
little
knots
or
loops,
as
shown
in
fig.
5.
6
if
the
upper
tension
is
too
tight,
then
the
under
thread
will
be
drawn
up,
as
shown
in
fig.
6.
Fig.
7
shaws
the
locking
of
both
threads
in
the
centre
of
the
material
as
result
of
the
right
regulation
of
the
tens
ion.
Raising
the
presser
foot,
the
tension
is
released
auto
matically,
permitting
easy
removal
of
the
material
from
underneath
the
presser
foot
which
should
be
done
in
the
direction
of
the
forward
feeding,
as
otherwise
the
needle
is
likely
to
break
or
be
bent
which
causes
skipping
of
stitches
and
thread
breaking.
