REGULATOR
(Refer
to
Plate
1A)
The
dialed
regulator
located
on
top
of
the
Cylinder
Base
raises
and
lowers
the
ridge
forming
disc
to
get
the
correct
needle
penetration
in
the
work
being
done
to
form
a
blind
stitch.
The
word
"More"
indicates
more
depth
and
"Less"
indicates
less
depth
of
needle
penetration.
From the library of: Superior Sewing Machine & Supply LLC

The
regulator
also
limits
the
amount
that
the
disc
can
be
raised
in
order
to
protect
the
needle
point
from
striking
the
ridge
forming
disc.
The
adjustment
is
made
by
turning
the
regulator
in
the
"More"
direction
as
far
as
possible
to
stop
pin
inside
of
the
regulator.
A
needle
must
be
in
the
needle
carrier
and
in
contact
with
the
needle
guide
and
point
of
needle
over
the
ridge
forming
disc.
Now
remove
the
set
screw
18-924
(See
Plate
No.

and
adjust
screw
18-923
that
contacts
the
cradle
140-11
in
which
the
ridge
forming
disc
shaft
is
mounted
and
adjust
so
that
the
ridge
forming

will
lift
the
needle
off
of
the

which
is
equivalent
to

Reassemble
the
18-924
screw
and
set

18-923
in

These
two
screws
are
located

headed
adjusting
screw
18-922.
The
adjustment
for
the
spring
tension
for
correct

is
made
by
turning
nut
20-120,
located
in
front
of
cylinder
base,
turn
in
clockwise
direction
to
get
more

and
in

then
set
the

so
that
it
is
l/32"
below
and
parallel
with
the
bottom
of
the
presser
foot,
for
light
and
medium

ma-
terials;
for
heavy
work,
the
feed
must
be
brought
below
the
press-

foot
about
3/64".
The

is
adjustable
from
three
to
eight
stitches
per

There
must
be
enough
pressure
applied
to
hold
the
work
from
moving
when
the
needle
penetrates
the
material,
for
if
the
material
moves

ADJUSTING
AND
SETTING
THE
LOOPER
To
secure
the
correct
adjustment
of
the
looper,
the
following
steps
should
be
taken
and
in
the
same
sequence
as
here
given:
The
looper
is
first
adjusted
as
the
looper
is
taking
the
loop
from
the
needle.
The
position
for
the
long
prong
of
the
looper
is
to
have
the
point
of
this
prong
3/32"

the
inner
end
of
the
needle
eye
and
the
point
of
the

is
greater
than
1/32'',
then
the

in
the
foot,
adjust
so
that
the
