INSTRUCTIONS FOR OPERATING THE MACHINE
Raise the presser foot (2, Fig 3) by means of the presser bar lifter
(3, Fig. 3) to prevent injury to the foot (2, Fig. 3) and feed (1, Fig. 3).
FIG. 3. FRONT VIEW OF THE MACHINE
It is necessary to understand the stop motion (5, Fig, 3) by which the balance wheel (4, Fig.
3) can be released when required, thus enabling the operator to become proficient in the use
of the treadle, and permitting the winding of bobbins without running the stitching mechanism.
It also allows the operator to wind bobbins without removing partially sewn work and without
unthreading the machine.

To release the balance wheel (4, Fig. 3, page 3) turn the stop motion screw (5, Fig. 3, page 3)
over toward you. It will be necessary to hold the balance wheel while loosening the stop
motion screw.
After releasing the balance wheel, place your feet upon the treadle and with the right hand
turn the balance wheel over toward you. This will start the band wheel, treadle and pitman,
the sewing mechanism having been disconnected.
Continue the motion thus begun by an alternate pressure of heel and toe, until a regular and
easy movement is acquired, and the balance wheel kept continuous rotation by use of the
feet alone.
When you are thoroughly familiar with the treadle movement, and can restart the machine
without turning the balance wheel in the wrong direction tighten the stop motion screw to
connect the balance wheel with the stitching: mechanism.
Place a piece of cloth under the presser foot, let the foot down upon it, and operate the
machine in this way without being threaded, until you have become accustomed to guiding
the material.
To Ensure Perfect Action of the Machine
The balance wheel 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.

To Take Out the Bobbin
Draw to the left the slide in the bed of the machine Reach down with the thumb and forefinger
of the left hand, open the bobbin case latch (2, Fig. 4) 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 downward and the bobbin will drop out.

To Wind the Bobbin
Release the balance wheel (4, Fig. 3) by turning the stop motion screw (5, Fig. 3) over toward you.
FIG. 5. MACHINE THREADED FOR WINDING THE BOBBIN
Place the bobbin on the bobbin winder spindle (8, Fig. 6) and push it up closely against the
shoulder, having the small pin in the spindle enter the slot in the side of the bobbin. Put the
spool of thread on the spool pin (1, Fig. 5). Pass the end of the thread into the thread guide
(2, Fig. 5) at the left and near the top of the arm, then up into the lower eyelet (3, Fig. 6) of
the bobbin winder thread guide, into the notch (4, Fig. 6) and pass the thread through the slot
in the left side of the bobbin from the inside. Press the bobbin winder pulley (5, Fig. 6) down
on the balance wheel hub, and the latch (7, Fig. 6) will drop down and hold it. Then operate
the treadle the same as for sewing.

The end of the thread must be held by the hand until a few coils are wound and should then
be broken off. When sufficient thread has been wound upon the bobbin, the bobbin winder is
automatically released from the balance wheel.
If the pressure of the rubber ring (5, Fig. 6) against the hub of the balance wheel is
insufficient for winding the bobbin, loosen the adjusting screw (6, Fig. 6) and press the bobbin
winder lightly until the rubber ring is in contact with the hub of the balance wheel; then tighten
the screw.

leading on top from the left toward the right
(see Fig. 7).

Then pull the thread into the slot in the edge
of the bobbin case (see Fig. 8), draw the

To Replace 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 centre stud (1, Fig. 4) of the shuttle
body with the position finger (1, Fig. 10) 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. Allow the thread to hang free and close the slide in the bed of the machine.

To Set the Needle
Turn the balance wheel over toward you until the needle bar (9, Fig. 5) moves up to its
highest paint, loosen the thumb screw (10, Fig 5) in the needle clamp (11, Fig. 5) and put the
needle up into the clamp as far as it will go, with its flat side toward the right, then tighten the
thumb screw.
To Thread the Needle
(See FIG. 11)
Turn the balance wheel over tow toward you
until the thread take-up lever (5) is raised to
its highest point. Place the spool of thread on
the spool pin at the top of the machine, lead
the thread toward the left through the thread
guide (1) at the back and at the top of the
face plate, down, under and from back to
front between the tension discs (2) up back of
the tension thread guard (3), down into the
loop of the takeup spring (4), up and from
back to front through the hole in the end of
the thread take-up lever (5), down into the
eyelet (6) in front of the face plate, into the
lower wire guide (7), then from left to right
through the eye of the
needle (8).
Draw about two inches of thread through the
eye of the needle with which to corn commence sewing.
