WINDING THE BOBBIN
Disengage the hand wheel (5, Fig. 3;) from the stitching mechanism by turning the clutch (6,
Fig. 3) toward you or counterclockwise.
Place a spool of thread on one of the spoof pins. Lead thread through the upper thread guide
on the arm and down through the tension disc (9, Fig. 4) at the base of the machine. Run end of
thread through a hole in the bobbin edge and place bobbin B on spindle of. bobtm winder (4,
Fig. 4) fitting the notch on bobbin over small pin on spindle. Push bobin winder pulley against
hand -wheel. Hold thread end loosely and start machine slowly.
Bobbin will stop v/inding when it is filled. Turn clutch away from yd until sewing mecha
nism is again engaged so that needle moves when you turn the hand wheel.
Break off loose thread end used to start the winding and thread bobbin as stated on page 6.

SETTING THE NEEDLE
See Fig. 5. Raise the needle bar A to its highest
point, turning wheel toward you by hand.
Then loosen the needle clamp screw B and the
needle can be inserted into clamp C. Place needle
(flat side to right) in the needle clamp and push it
upward as iar as it will go into the needle clarnp
hole, tightening the needle clamp screw securely
with a screw driver.
Alter changing the needle make one compíete revolution ol the balance wheel by

THREADING THE BOBBIN CASE
Step 1 (.llustr.led in Fig, 7). Hold bobbio case between thumb and lo.ellnger ot lelt hand,
eo that the slot in the edge ol the bobbin case ia on lop. Take the bobbin between thumb and
forefinger of right hand so that the thread on lop leads from loft to tighf.
Step 2 Insert bobbin into bobbin case, pull the thread into the slot ol the bobbin case as
shown in Fig, 8 and draw it under tension spring and into the fork-shaped opening ol the spring
as shown in Fig. 9.

PLACING BOBBIN CASE IN SHUTTLE
Raise needle bar to highest position, and slide cover plate
to the left. (See 12, Fig. 1) Hold the bobbin case latch, (D,
Fig. 10) between the thumb and forefinger of the left hand,
with at least three inches of thread running from the top of
the bobbin case to the right. Insert and center the bobbin
case on the stud of the shuttle body, (C). Be sure the
bobbin case finger, (E), is opposite the shuttle race notch (A).
Press the bobbin case (B) into the shuttle as far as possible
until latch catches on the center post of the shuttle. THEN
release the bobbip case latch, (D). Press bobbin case again

SETTING THE STITCH LENGTH
The length of the stitch is regulated by the dial, shown in Fig. 13. Near 0 is the shortest
stitch and 5 is the longest, but the dial may be set at any spot between the markings for a
variety of lengths. Turn the dial to the right to lengthen and to the left to shorten the stitch.
The number stitch length you choose is indicated by the pointer.

ADJUSTING THE TENSIONS
Always adjust the upper tension with the presser foot down,
as the tension is released when it is raised. To increase the
tension on the upper thread, turn dial (Fig. 14) to the right, or
clockwise; to decrease, turn to the left. The higher the number
on the dial the tighter the tension. Before adjusting lower tension
be sure that the machine is threaded properly.
When it is necessary to change the bobbin tension, turn
the small screw (Fig. 16) on side of the bobbin case clockwise to
tighten, counterclockwise to loosen.

Wheri the upper and under tensions are properly
balanced, a perfect stitch will be formed with both
threads interlocking in fabric (Fig. 15-A).
When the upper tension is too tight, the lower
thread is pulled up over the upper thread which is
lying flat on the fabric (Fig. 15-B).
When the upper tension is too loose, the upper
thread forms loops over the lower thread lying flat
on the fabric (Fig. 15-C).

ADJUSTING PRESSURE AND FEEDING OF FABRIC
GENERAL SEWING. Usually for straight sewing and various embroidery work, the pressure
bar cap or darning release, Fig. 18, is at its lowest position and the feed at its highest level-with
the drop feed button marked UP pressed all the way down. Fig. 17.
SEWING THIN OR LIGHT WEIGHT FABRICS
When lighter pressure is required to sew satisfactorily on thin
silk or flimsy material, the pressure cap should be about halfway
down. Release all the way by pressing the snap lock. A, Fig.
19, and then press cap B down again to half-way spot. Lower
the feed slightly by pressing the DOWN button (Fig. 17) to the
red line.
Fla. 18
DARNING AND MENDING
In order to move the fabric freely in any
direction for darning and mending, release
the pressure cap B completely pressing
down on the snap lock. A, Fig. 19. Press
DOWN button (Fig. 17.) all the way down,
which drops the feed well below the needle
plate. To return feed to normal, press the
UP button all the way down.
