SPEED
RECOMMENDATION
39500
9M
machines
have
been
tested
in
their
complete
stitch
range
at
their
maximum
rated
speeds.
Varied
sewing
applications
may
necessitate
operating
at
a
lower
speed.
When
operating
from
50-100%
machine
running
cycle
and
longer
than
recommended
stitch
length,
it
may
be
necessary
to
reduce
machine’s
speed
by
10-15%.
The
9M
is
a
precision
manufactured
and
tested
sewing
machine,
and
are
run-in
at
the
factory
to
achieve
maximum
speed.
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
Speci
fication
No.

Remove
oil
filler
cap
(A,
Fig.
1),
add
oil
until
indicator
is
level
with
top
line
of
sight
gauge
(B).
Replace
oil
fil
ler
cap
and
run
machine
30
-
40
seconds
at
half
speed
to
fill
the
system.
Check
sight
gauge
and
add
oil
as
required
until
the
indic
ator
registers
half
way
between
the
two
lines
of

Approximately
14
to
16
ounces
(354.9

LUBRICATION
(Continued)
To
maintain
maximum
reconnended
speed
and
servicability
of
this
equipment
when
operating
continously,
the
oil
must
be
changed
at
least
every
six
months.
In
no
case
should
oil
remain
in
the
machine
for
more
than
one
year.
Oil
drain
plug
is
located
at
rear
of
machine
near
bottom
edge
of
base.
ALWAYS
change
oil
filter
whenever
oil
is
changed.
It
is
recommended
to
change
oil
filter
after
the
first
three
months
of
operation
-
or
immediately,
when
oil
is
not
visible
in
the
oil
filler
cap
while
machine
is
running.
NOTE:
An
oil
by-pass
valve
is
incorporated
in
the
lubricating
system
so
if
oil
filter
should
become
clogged
(oil
not
visible
in
filler
cap
while
machine
is
running)
machine
will
automatically
revert
to
the
splash
system,
but
it
is
not
advisable
to
operate
for
an
extended
length
of
time.
To
replace
filter,
unscrew
oil
filter
cover
assembly
(A,
Fig.
2),
which
should
only
be
hand
tightened
and
remove
filter
from
shaft
of
cover
assembly.
Due
to
tight
tolerances,
it
may
be
necessary
to
screw
the
old
filter
off
and
the
new
filter
on
the
shaft
of
the
cover
assembly.
Replace
cover
assembly
(hand
tight)
and
recheck
oil
level.
NEEDLES
Each
needle
has
both
a
type
and
size
number.
The
type
number
denotes
the
kind
of
shank,
point,
length,
groove,
finish
and
other
details.
The
size
number,
stamped
on
the
needle
shank,
denotes
the
largest
diameter
of
blade,
measured
midway
between
shank
and
eye.
Collectively,
type
and
size
number
represents
the
complete
symbol,
which
is
given
on
the
label
of
all
needles
packaged
and
sold
by
Union

To
have
