and operate the machine in this ijay without being threaded, until you have
become accustomed to guiding the material.
TO ENSURE PERFECT ACTION OF THE MACHINE
The machine pulley must always turn over toward the operator.
Do not run the machine with the presser foot resting on the feed without
cloth under the presser foot.
Do not run the machine when both bobbin case and needle are threaded
unless there is material under the presser foot.
Do not try to help the machine by pulling the fabric, lest you bend the
needle; the machine feeds the work without assistance.
The slide over the bobbin case should be kept closed when the machine
is in operation.

From the library of: Superior Sewing Machine & Supply LLC

Hold the thread as shown in Fig, 6. Turn the thread over toward you
between the thumb and fot'efinger of the right hand; if left twist, the strands
will wind tighter; if right twist, the strands will unwind,
TO REMOVE THE BOBBIN
Turn the machine pulley over toward you until the needle moves up to its
highest point. Draw out the slide in the bed of the machine, reach down \d.th
the thiimb and forefinger of the left hand, open the bobbin case latch (I,
Fig. 7) and lift out the bobbin case. While the latch remains open, the
bobbin is retained in the bobbin case. Release the latch, turn the open
end of the bobbin case downwardly and the bobbin will drop out.

From the library of: Superior Sewing Machine & Supply LLC

Fasten bobbin winder to table with its driving pulley in front of the machine
belt (see Fig. 8), so that bobbin winder driving pulley (K) will make firm
contact with machine belt when thumb latch (L) is pressed down and pulley will
be released from contact with belt when sufficient thread has been wouxld upon
the bobbin.
Place bobbin on spindle, pushing it on as far as it will go and pass thread
through threading points, as shown in Fig. 8.
Wind end of thread around the bobbin a few times. Press down on thumb
latch (L), pushing driving pulley (K) over against belt, as shown in Fig. 8.
Start machine.
Bobbin winder will stop automatically, when the amount of thread for which
it is regulated is wound upon the bobbin. For more thread on bobbin, turn screw
(M) inward; for less thread on bobbin, turn screw (M) outward.
When winding a bobbin with fine thread, a light tension should be used.
Adjust the knurled nut (N, Fig. 8), to regulate the tension.
If thread winds unevenly on bobbin, loosen screw (O) and move tension bracket
(P) to the left or right, as required. Tighten screw (O).
Bobbin .can be wound while the machine is stitching.
Note: Occasionally apply a few drops of oil to tiie oil well, shown in
Fig. 8, on top of the bobbin winder frame.
TO THREAD THE BOBBIN CASE

Then pull the thread into the slot in the edge of the bobbin case (see
Fig. 10), draw the thread down under the tension spring and into the delivery
eye at the end of the tension spring (see Fig. 11).
TO REPUCE THE BOBBIN CASE
After threading, take the bobbin case by the latch holding it between the
thumb and forefinger of the left hand; place the bobbin case on the center
stud (J, Fig. 7, page 5) of the shuttle body with the position finger opposite
the notch at the top of the shuttle race, release the latch and press the
bobbin case back until the latch catches the groove near the end of the stud
(see Fig. 12). Allow about two inches of thread to hang free.

TO SET THE NEEDLE
Turn the balance wheel over toward you until the needle bar moves up to
its highest point; loosen the screw (A, Fig. 1, page 1) in the needle clamp
and put the needle up into the clamp as far as it will go, with the long groove
of the needle toward the left and the eye of the needle directly in line with
the arm of the machine, then tighten the screw (A).

Fig. 13 Threading the Needle
Place the soool of thread on
the spool pin on top of the machine
or pass the needle thread from
the unwinder through the thread
hole on the spool pin^ then pass
the thread from the spool over
between the thread retaining discs
(l) at the rear of the upper end
of the face plate, down under from
back to front between the tension
discs (2) at the front of the
face plate) over, the tension
thread guard (3) above the tension
discs, into the hook of the thread
take-up spring (4), up and toward
you through the hole in the end
of the thread take-up lever (5),
down through the face plate
thread guard (6) at the front of
the face plate, into the needle
clamp thread guide (7) at the
lower end of the needle bar and
from left to right through the
eye of the needle (B), Draw
about two inches of thread
through the eye of the needle with
which to commence sewing.
TO PREPARE FOR SEWING
With the left hand hold the end of the needle thread, leaving it slack
from the hand to the needle, turn the balance wheel over toward you until
the needle moves down and up again to its highest point, thus catching the
bobbin thread; draw up the needle thread and the bobbin thread will come up
with it through the hole in throat plate (see Fig. 14.). Lay both threads
back under the presser foot.

Fig. 14. Drawing up the Bobbin Thread
TO COMMENCE SEWING
Place the material beneath the presser foot^ lower the presser bar and
commence to sew^ turning the machine pulley over toward you.
TO REMOVE THE WORK
Let the thread take-up lever rest at its highest point, raise the presser
bar, draw the work back and cut the threads close to the material.
TENSIONS
For ordinary stitching, the needle and bobbin thread should be locked
in the center of the thickness of the material, thus:
Fig. 15 Perfect Stitch
If the tension on the needle thread is too tight, or if that on the bobbino
thread is too loose, the needle thread will lie straight along the upper
surface of the material, thus:
Fig. 16 Tight Needle Thread Tension

From the library of: Superior Sewing Machine & Supply LLC

If the tension on the bobbin thread is too tight, or if that on the
needle thread is too loose, the bobbin thread will lie straight along the
under side of the material, thus;
Fig. 17 Loose Needle Thread Tension
TO REGUUTE THE TENSIONS
The tension on the needle thread should only be regulated when the presser
bar is down. Having lowered the presser bar, tvirn the small thumb nut (B,
Fig. 1, page 1) at the front of the tension discs over toward you to
increase tne tension. To decrease the tension,turn this thumb nut over from
you.
The tension on the bobbin thread is regulated by the screw (Q, Fig. 9,
page 6) in the bobbin case tension spring. To increase the tension, turn this
screw over to the right. To decrease the tension, turn this thumb nut over
to the left.
When the tension on the bobbin thread has been once properly adjusted,
it is seldom necessary to change it, as a correct stitch can usually be
obtained by varying the tension on the needle thread.
TO REGULATE THE LENGTH OF STITCH
The length of stitch is regulated by the thumb screw (C, Fig. 1, page l)
in the slot on the front of the upright part of the arm. To lengthen the
stitch, loosen the thumb screw (C) and move it downwardly. To shorten the
stitch, loosen the thumb screw (C) and move it upwardly. When the desired
length of stitch has been obtained, tighten the thumb screw (C).
TO REGUUTE THE PRESSURE ON THE MATERIAL
The pressure on the material is regulated by the thumb screw (G, Fig. 5»
page 3) on the top of the machine. To increase the pressure, turn this thumb
screw over to the right. To decrease the pressure, turn this thumb screw
over to the left. The pressure should only be heavy enough to enable the
feed to move the work along evenly.
TO REGUUTE THE UPPER FEED
The upper feed is regulated by loosening the lock screw (S, Fig. 18)
and turning the large thumb screw (T, Fig. 18) to the left for a shorter
stitch, or to the right for a longer stitch. The lock screw (S) should be
securely tightened after the adjustment is made.

INSTRUCTIONS
FOR
ADJUSTERS AND MACHINISTS
TO TIME THE NEEDLE WITH THE SHUTTLE
Fig. 19 Needle and Shuttle Correctly
Timed (Shuttle Race Broken
to Show Point of Shuttle and
Needle)
- 12 -
See that the needle is pushed
up Into the needle clamp as far
as it will go.
Turn the machine pulley over
toward you until the point of
the shuttle reaches the center
of the needle on the upward
stroke of the needle bar.
When the shuttle is in this
position, the top of the eye of
the needle should be I/I6 inch
below the point of the shuttle,
as shown at (U), in Fig. 19.
If the eye of the needle is
not the correct distance below the
point of the shuttle, loosen the
screw which fastens the needle bar
in position in the needle bar
connecting stud (V, Fig. 19).
(This screw can be reached through
the hole (H, Fig. 5, page 3)
provided for the purpose in the
arm). After loosening the screw,
move the needle bar up or down
in the needle bar connecting
stud until it is at the required
height, then securely tighten
the screw.
From the library of: Superior Sewing Machine & Supply LLC

TO REMOVE AND REPLACE THE SHUTTLE RACE
Turn the machine pulley over toward you until the needle bar moves up to
its highest point.
Take out the two screws (W, Fig, 20) which hold the shuttle race in position
and remove the shuttle race. Then remove the shuttle from the shuttle race.
When replacing the shuttle race, have the needle bar at its highest point
and turn the shuttle in the race so that it correctly engages the shuttle
driver, then securely fasten the shuttle race in position by means of the
two screws (W).
TO RAISE OR LO\^R THE FEED DOG
The feed lifting rock shaft crank (X, Fig, 20) should be set so that
when it-raises the feed bar to its highest point, slightly less than the
full depth of the teeth project through the slots in the throat plate. To
raise or lower the feed dog, loosen the clamping screw (Y, Fig.
and move the feed lifting rock shaft crank (X) until the feed dog is set
at the required height, then securely ti^ten the clamping screw (Y),
Fig. 20 Adjustment for Raising and Lowering
the Feed Dog
TO TIME THE FEEDING MECHANISM
The feeding mechanism should be timed so that the feed dog starts its
feeding movement (away from the operator) when the needle bar commences its
downward stroke. The feed should always finish its feeding movement before
the needle reaches the goods on its downward stroke.
When it is necessary to time the feeding mechanism, press Idae thumb
screw (C, Fig, 1, page l) down to its lowest point for the longest stitch
and remove the square cover plate at the back of the machine. Loosen the
feed cam set screw ^Z, Fig. 21) and turn the feed cam (Ai, Fig. 21) until
the feed is correctly timed as instructed above, then securely ti^ten the
set screw (Z).

iM
Fig, 21 Adjustment for Timing Feeding Medaanism
TO ADJUST THE THREAD TAKE-UP SPRING
The thread take-up spring (Bi, Fig. 22) should be set so that when the
eye of the needle reaches the goods on the downward stroke of the needle bar,
the spring will be through acting and will rest against the thread take-up
spring regulator plate (Ci, Fig, 22),
Fig, 22 Adjustment of Thread
Take-up Spring
If the thread take-up spring is not
correctly set, loosen the set
screw (Di, Fig, 22) which holds
the thread take-up spring regulator
plate (Gi) in position and lower
the plate (Ci) for more movement
of the spring, or raise it for
less movement. When the spring is
correctly set, securely tighten
the set screw (Di ),
The tension on the thread
take-up spring (Bi) is regulated
by loosening the set screw
(Ei, Fig, 22) at the side of
the face plate and turning the
tension screw stud (Fi, Fig, 22)
over toward you to increase the^
tension, or over from you to
decrease the tension. When* the
desired tension is obtained,
securely tighten the set screw
(El),
The tension on the thread take-
up ^ring should be just sufficient
to take up the slack of the needle
thread until the eye of the needle
reaches the goods in its descent.
