Selection of proper needle size
is
determined
by
size of the thread used.
Thread should pass freely through needle
eye
in order to
produce
a
good

LUBRICATION
Use
a
straight
mineral oil with a Saybolt viscosity of
90
to
125
seconds
at
100
degrees
F.
This
is
equivalent to
Union
Special Corporation Specification
No.
175.
Before operating,
fill
machine
with
oil
at
plug screw
(A,
Fig. 1).
While
filling
machine
with
oil,
check
gauge
(B).
When
proper oil level
is
reached,
gauge
needle will
register
on
black
line
marked
11
FULL

•
Oil
must
be
added
when
gauge
needle
registers
on
black
line
marked
"LOW'.
Al-
though
the
machine
can
be
operated safely
when
gauge needle
registers
in the
"OPERATE"
zone,
it
is
recommended
to
always
check
oil
level before
operating,
to
be
sure
machine
is
filled
with
oil
to
the
"FULL"
mark.
CAUTION:
DO
NOT
over
fill
machine.
To
drain
oil,
remove
plug
screw
(C), or
low-
er
crank
chamber
cover
on
back
of
machine.
Oil
must
be
changed
every
2000
operating hours to
minimize wear.
On
new
machines, or a
machine
out of service
for
an
extended period of time; lubricate
machine
as follows:
Remove
head
cover, clean.out
lint,
then
di-
rectly
oil
needle bar link
and
needle bar.
Re-
place
head
cover
and
fill
machine
with
oil
to
proper
level.
Run
machine
at
low
RPM
to ensure
proper
lubrication
of
components
preventing
any
damage
which
may
occur
from
lack of
oil

machine
and
start
operating
on
a
piece of fabric. Refer to threading
diagram
(Fig.

for the threading of these
machines.
THREAD
TENSIONS
The
tension
on
the needle thread should
be
only
sufficient
to
produce
uniform
stitches
on
the under surface of the fabric.
The
looper thread tension
is
applied
at
the
cast-off
support tension disc
assem-
bly,
and
the adjusting nut should
be
set
so
that
the tension
on
the looper thread
is
just
sufficient
to steady the thread.
THREAD
TENSION
RELEASE
The
thread tension release
is
set

in the following
manner:
With

set
needle thread take-up wire
(A,

so
its
lower extended surface
is
1 7/16 inch
(36.5mm)
above
centerline of

and
3/4 inch
(19.0mm)
across the centerlines of
its
vertical surfaces
(See
Fig.
14A).
Fig.

Set looper thread guide eyelet
(A,
Fig.

so
its
left
outer surface
is
3/4 inch
(19.0rrm)
from
the
left
side
of looper thread take-up (B),
(See
Fig. 15).
Adjust looper thread tension with nut
(B,
Fig.

to a
minimum
required for controlling the looper thread
(light).
Set the thread index eyelet
(C)
at
11
3
11
on
the
adjusting plate
(D).
Changing
the needle thread tension
only, with nut (E), balance the
stitch
so
that
when
6
inches
(152.4mm)
of
sewn
seam
are raveled back, the needle
thread
is
approximately as long as the looper thread.
Al
inch
(25.4mm)
difference in lengths
is
permissible.
NOTE:
Use
a
sample
of
the material to
be
sewn.
Maintaining
this
needle thread tension,
move
thread index eyelet
(C)
up
to
toward
11
L

to obtain a looser
seam
(longer needle loops)
and
toward

FEEDING
PRESSER
FOOT
(Continued)
As
a preliminary
setting,
adjust spring regulator nut
(A,
Fig.
17)
on
feeding
presser
foot
so
the distance
from
the top of spring
(B)
to the
yoke
(C)
is
5/8 inch
(15.9mm),
(See
Fig. 17).
Assemble
the feeding presser
foot
to
presser bar.
With
presser foot resting
on
throat
plate
and
feed
dog
down,
press
down
on
spring
regulator
nut
{A,
Fig.
17)
until the
marks
on
presser
foot bottom line
up
with the centerline of needle,
while keeping the needle in the center of needle
slot,
tighten
set
screw
(D)
securing presser bar
guide
to
the presser bar,
making
sure stop
screw
in
presser
bar guide
is
resting
on
the
bed
casting.
Replace presser spring
and
presser spring reg-
ulator.
Turn
presser bar spring regulator
screw
down
until
the thread portion
is
level with the
head
casting.
NOTE:
Any
change
in the alignment of needle in
re-
lationship
to the
marks
on
the presser foot
bottom
probably
means
that
the stop
screw
of the presser bar
guide
was
not seated against
bed
c3sting before lock-
ing
set
screw.
When
the presser foot
is
lifted
off
the bare Fig.
17
throat
plate,
the foot should
move
back
only
slightly,
less
than 1/64 inch
(.4mm).
The
stop
screw
{E,
-Fig.
17)
on
the yoke,
which
is
set
at
the
factory,
can
be
readjusted
if
necessary, should
this
dimension
become
changed.
CHECK
Presser foot
at
back
of needle
slot
should cover
most
of throat plate land
when
resting
on
the bare throat
plate.
When
the presser foot
bottom
is
raised
by
material
so
that
the feeding foot
spring bottoms, the
back
of the needle
slot
should
clear
the needle.
The
main
press-
er
bar should not
lift
before the feeding foot spring bottoms.
The
purpose of the feeding foot
is
to
make
the top
and
bottom
ply of cloth feed
the
same
amount
without pulling
on
the
bottom
ply.
The
5/8 inch
{15.9mm)
setting
on
the feeding foot spring usually gives a
good
matching of
piles
and
a strong feeding
pull.
Reducing
this
pressure will tend to feed the top ply
more.
Increasing
this
pressure will tend to feed the
bottom
ply
more.
TORQUE

It
will
be
noted in the

example
that
the
eccentric,
ball stud
and

so
the complete sub-assembly should
be
ordered.
At
the
back
of the
book
will
be
found
a numerical index of
all
the parts
shown
in
this
book.
This
will
facilitate
locating the
