measured
in
thousandths
of
an
inch
midway

Collectively,
type
number
and
size
number
represent
the

r1eedle
size
should
be
determined
by
the
size
of
the
thread

to
produce
a
good
stitch
formation.
For

OILING
INSTRUCTIONS
There
are
three
oil
reservoirs
on
the
Class
62200
machines
which
are
filled
through
the
oil
cups
"C",
"D"
and
"E"
(Fig.
1).
Each
hook
is
automatically
lubricated
from
its
own
reservoir
by
a
spiral
oil
screw.
The
amount
of
oil
re-
quired
for
each
hook
may
be
adjusted
for
by
a
metering
screw
located
at
the
bottom
of
the
reservoir.
The
ma
in
reservoir
which
houses
the
gears,
stitch
regulating
mechanism,
needle
feed
driving
mechanism,
upper
main
shaft
bearing
etc.,
lubricates
these
parts
by
a
splash
action
and
also
supplies
oil
to
the
lower
feed
mechanism
through
the
lower
shaft.
The
level
of
the
oil
in
the
three
main
re-
servoirs
can
readily
be
observed
at
the
lucite
gauges
"F"
,·
"G''
and
"H".
The
manually
oiled
holes

and

and

respectively.

(C)
until

is
moved
into
contact
with
machine
belt,
and
is
locked
in
that
position.
When
the
ma-
chine
is
operated,
the
bobbin
will
be
rotated
and
filled
until
the
thread
engages
the
automatic
throw-
out
member,
which
disengages
the
pulley.
The
extent
to
which
the
bobbin
is
filled
can
be
varied
by
the
regulating
screw
(D).

The
tension
post
bracket
is
mounted
on
the
winder
base,
and
can
be
shifted
from
left
to
right
by
loosening
screw
(E)
so
that
any
tendency
of
the
bobbin
to
wind
unevenly
may
be
readily
corrected.
The
purpose
of
the
bobbin
winder
is
to
assure
the
operator
a
full
bobbin
at
all
times.
When
the
bobbin
in
the
machine
is
used
up,
replace
it
with
a
full
one
and
begin
to
wind
the
empty
bobbinimmediately.
Bobbins
can
be
rewound
while
machine
is
sewing.
INSERTING
THE
BOBBIN
Place
the
bobbins
in
the
hooks
so
that
they
unwind
in
th
e
opposite
direction
to
that

TIMING
(Continued)
Upon
location
of
the
needle
bar
in
its
maximum
"down"
position,
the
timing
may
be
checked
by
looking
into
the
main
reservoir
at
bottom.
If
the
machine
is
timed
properly,
the
flexible
coupling
pin
(C,
Fig.
9)
will
line
up
with
the
center
of
the
lower
main
shaft
(D).
It
will
also
be
noted
that
the
end
of
the
pin
(C)
whichis
held
in
gear
(A)
willline
up
with
the
small
c~sting
boss
(B).
Since
the
flexible
coupling
head
(E)
has
two
pins,
located
180
apart,
care
must
be
taken
to
choose
the
correct
pin
for
the
timing
checking.
The
correct
pin
(C)
which
is
farthest
away
from
the
two
hub
securing
screws,
is
to
be
used
for
this
check.
If
timing
is
incorrect,
it
will
be
necessary
to
move
the
lower
main
shaft
(D)
to
the
left
far
enough
to
remove
it
from
the
coupling.
The
gear
with
the
hub
and
its
pins
should
then
be
remeshed
with
the
idler
gear
to
produce
the
location
of
the
correct
coupling
pin
(C)
as
shown
in
the
illustration.
Ifthe
cou-
pling
hub
(E)
is
removed
from
the
lower
main
shaft,
the
hub
screw
that
is
used
as
the
timing
screw
on
the
lower
main
shaft
timing
flat,
is
the
first
screw
coming
into
view
as
the
shaft
is
turned
in
operating
direction.
Replace
gear
case
cover
ofbottom

Use
no

on
any

NOTE:
There
should
be
about
1/32
inch
space
between
the
main
shaft
collar
(F)
and
the
flexible
coupling
gear
(A)
when
this
coupling
gear
is
fixed
in
operating
position
at
extreme
right.
Final
check
on
timing
can
be
made
after
machine
is
adjusted
by
observation
of
the
entry
of
the
needles
into
the
feed
dog
holes
(A,
Fig.
10).
The
point
of
the
needles
should
enter
the
feed
dog
holes
as
th
e
feed
dog
is
just
passing
the
top
of
the
throat
plate.
LOCATING
THE
FEED
DOG
Having
previously
spaced
the
needle
bar
with
the
presser
bar,
the
position
of
Fig
10
feed
dog
with
respect
to
the
needles
may
•
be
checked.
The
feed
dog
is
to
be
so
aligned
in
the
line
of
feed
that
the
needles
will
enter
the
needle
holes
at
the
center
or
just
slightly
to
the
front.
Should
an
enlarged
needle
hole
be
required,
countersink
the
feed
dog
from
the
top,
and,
if
possible,
do
not
enlarge
the
bottom
of
the
needle
hole.
To
center
needles
in
the
feed
dog
in
the
line
of
feed,
remove
the
bottom
cover
of
the
main
reservoir
exposing
the
clamp
screw
(G,

inthefeeddriving
arm.
Loosening
the
screw
enables
the
feed
rocker
shaft
to
be
rotated
to
secure
the
proper
location
of
the
feed
dog.
Re-
tighten

and
replace

To
