1. Setting up Machine for Work
Unpack machine from its shipping box, making certain that you remove from box
all component parts and accessories.
A.
Location
(Figs.
1-2)
Place machine on a firm table, preferably near its right front corner. Attach
machine near edge
of
table using table clamp which
is
included with the accessories.
Table clamp
is
inserted into groove in base place
of
machine either from front or right
side.
The
selection
of
the clamp groove depends on how you desire to place machine on
table
to
suit your
own
convenience. Make sure machine
is
clamped tightly to keep it
from falling
off
table. See
Figs.
1 and 2 for details
of
clamping.

Lubrication
is
important
for the trouble-free operation and long service life
of
the
machine.
Therefore,
after setting-up machine
as
per
paragraph
1,
drop a sewing
machine oil into all the holes indicated by arrows on Fig. 7, and also drop oil
onto
the
inner
moving
parts
after
opening the side
cover
and rear
cover
of
machine.
Daily and
before
operating
machine, place one
or
two
drops
of
sewing machine
oil into all the oil holes indicated by
arrows
on Fig. 7.
To
assure clean
operation,
it
is
suggested that oiling be done upon completion
of
the
work.
This will
allow
excess oil to drip
off
and only the needed quantity will
remain. Be
certain
to
wipe
off
machine all excess oil before
starting
to
work.
Also
before
sewing,
operate
machine for about a minute
or
so
with
the knee lifter
depressed
to
eliminate
all excess lubricant.

When
reaching to thread tension device, enter thread first in rear eye
of
thread
guide (1). Then, lead thread between the
two
tension discs (2)
as
per Fig.

Now
enter it from behind through the front eye
of
thread guide. Lead thread
forward
to
front
of
machine. Enter thread from above into thread gruide (3), and eyelet
of
needle clamp (4).
As
this point, make certain that needle
is
in
extreme
left-hand position.
Now
pull
thread through needle eye from below
as
shown in Fig.

It
is
easier
to
pull thread through needle eye when

Inserting
the Work
Piece
and
Starting
to
Sew
(Figs.
13-14)
Depress knee lifter. This causes the cylinder bed
of
the machine to swmg
downward
and creates a gap between the presser foot and the cylinder bed. Insert the
work
in the gap just opened
in
such a manner that the folded
or
sewn edge
of
the
article
is
alongside the edge guide
of
the presser foot.

When
the article
is
in proper position, completely release the knee lifter.
Get
the
machine started slowly and
watch
the material
pass
edge guide rather than to observe
the action
of
the needle.
In case
of
sewing double folded edge
of
material, insert the material
as
per Fig. 14-
1.
In case
of
sewing single folded, insert the material
as
per Fig. 14-2.

Adjustment
of
Thread
Tension
(Figs.
15-16)
Different
kinds and weights
of
material
and
the various sizes
of
thread
require
respective
thread
tensions.
Thread
tension
is
regulated
by
turning
the tension
nut
located
at
the top
of
the machine arm.

To increase
thread
tension, turn the
nut
away
from you (clockwise).
To decrease the tension,
turn
the
nut
towards
you
(counter-clockwise).
Do
not turn, tighten,
or
loosen tension
more
than
about
one
quater
turn
at
one
time.
Test
for results
and
readjust,
if
necessary.

8. Regulating
Stitch
Length
(Fig.
17}
Open
side cover by loosing
two
clamp screws. Loosen
two
set screws
(1)
in stitch
regulating collar (2), and
turn
collar (2) until desired number
is
reached by indicator
groove (3)
of
eccentric. Then, tighten screws
(1)
securely.
When
delivered from
our
factory, the
number
for stitch length
of
the machine
is
b
"6"
set
to
e
at
.
Groove

Each
number
shows the following stitch length.

(M/M)
To have best choice
of
stitch length, recommend to have a few trial stitching on
different kind materials.
9. Adjustment of Needle Penetration
(Fig.
18)
The
depth
of
needle penetration into the
cloth
can
be
adjusted by turning the
plunger regulator located on front
of
the machine.

Fig. 18
From the library of Superior Sewing Machine & Supply LLC - www.supsew.com
To
increase needle penetration for light materials,
turn
the regulator
counter-
clockwise.
The
greater the number directly in front
on
the regulator dial, the deeper
the penetration
of
the needle. To lessen the penetration for thick materials,
turn
regulator clockwise.
To prevent damage to the needle and
the
machine, it
is
recommended to
begin
sewing
with
the least degree
of
penetration, and to sew a short length
of
seam.
Check
for catching
of
the material and apprearance, making
whatever
penetration
adjustments are required until stitching
is
as
desired.
NOTE:
Beginning and end
of
penetration adjustments are controlled by built-in
stops.
Do
not
force beyond its stops.
10.
Removal
of
the Work
from
the Machine
(Fig.
19)
Stop machine and turn handwheel away from you until needle
is
completely
out
of
the material (at highest position). Press knee lifter to the right and pull
the
work
piece
rearward
out
of
the machine
with
a quick stroke. This
will
lock the last stitch
and
break
the thread.

Skip
Stitch
Device
(Figs.
20-21)
The position
of
the lever at the right side
of
the machine controls the skipstitch
device.
When
this lever points towards
"No
skip", the needle catches the material at
every
stitch.
Pointing
towards "skip", the needle penetrates the material at every
other
stitch.
To
be assured
that
the machine works
as
desired, the lever should be pushed
in
either
direction
until stopped.
If
the lever
is
maintained at intermediate positions,
operation
of
the machine
is
not
reliable. Also note that every time operation
is
changed
from
skip
to
non-skip, needle penetration should be checked and readjusted,
if
necessary.
