C
rig. \
Loosen the BALANCE-WHEEL-})! OP-MOTION-SCREW Fig 3(A) toward you,
allowing the balance wheel to rut* free; place spool of thread on sppol pin Fig 4(A) at
the foot of the machine. Pass the.. tiread through tension-bracket Ifig. 4(B) and up to
the thread pressing lever Fig 4(Ch Wind thread from inside oul
around bobbin, which had been pa<;cd on the left end pin of the rubber ring Fig 4(D).
Be sure that the bobbin is presse 1to the end of the spindle. Press down the bobbin
and bobbin winder latch will drop down and hold the bobbin wirper-ring against the
balance wheel. Then operate the machine like by serving.
''continued on n«xt page)

The bobbin ivinder is automatically released, when sufficient thread
has been wound on the bobbin.
THREADING THE
Hold bobbin between thumb apd forefingefr (see Fig 5, 6, 7) and pull
out 2to 3" of thread. Guide thread into the cross slot in the edge of
the bobbin case. Pull thread unfeler the tension spring toward you into
the eye.

TO INSERT BOBBIN CASE
After turning the Balance "Wheel unftl
needle bar is at its highest point, insert
bobbin into the bed of the machine arid
lace it so that the center stud of the bop-
in case holder fits into the slot of the rac(e.
By inserting the bobbin case the hole must
be on top (as shown in figure 8), Press the
bobbin case gently into the bobbin case
holder, release at the same tim<fc the lafch
until the stud of the bobbin case holder
snans into the latch. At least 3to 4inches
of thread should hang freely fro-n the bob-
bin case. Close the bed slide.
UPPER THREADING
Turn Balance Wheel towards you until the.
take-up lever is raised to its highest point.
Place spool of thread on the spool pai of
the machine arm; pass thread over and
through the thread guide Fig. 10 (A) the
top corner of the face-plate, down and over v
the back to front between the tension-disc
Fig. 10 (B) up to thread guard Fig. 10 (C),
dowii into the hook of take-up Spring Fig.
10 (D) and over back to front through hole
in the end of the thread take-up-lever Fig.
10 (E) down into the eyelet of the face-
plate, Fig. 10 (F) into the lower wire-tttread
guide, Fig. 10 (G) then from left to (right
•8•

through eye of the needle Fig. 10 (H).
Draw about 2" of thread through the eye
of the needle with which to commence sew-
ing. Hold needle thread in your left hand,
turn balance wheel towards you until needle
moves up and down, and up again to its
highest point, catchiijg the bobbin thread,
which will be brought up that way through
the hole in the thread plate.
TO REGULATE THE PRESSURE
For darning and embroidering, release the
pressure by pressing down the automatic
darning lever 'A' Figure 9. Make sure the
Presser Foot is down when releasing the
pressure.
For ordinary sewing -reset the pressure
bjj pressing down on
*B' figure 9.
To increase the pres-
sure press down on
'B* Figure 9until
the desired pressure
is obtained. Ther6
should be jus't
enough pressure on
the foot to allow
the fabric to move
easily and to prevent
it from rising with
the needle.

Fig. II REGULATING THE THREAD TENSION
1%. 11 tff)
Fig. 11 fCi
TO REGULATE THE TENSION
If upper tension is too loose, under thread draws
upper thread down, thus forming'asmall knot or
loops, as shown in Fig. 11 (A). If upper tension
is too tight, under thread is drawn up as shown
in Fig. 11 (B). Fig. II (C) illustrates how the
threads lock in the center of the material when
tension is properly set.
Fig. 11 (D)
Fig. 11 (E)
V
The tension on the needle thread should be regulated on\y w>en the
pressor foot is down. Having lowered the presser foot, tinVi the
small rhumb screw (Fig. 1ID) at the front of /he tension discfc over
toward you to increase the tension. To decrease the tensionV turn
the thumb nut over from you. '
The tension on the bobbin thread is regelated by the screw (Fig. 11E) in the bobb
tension spring. To increase the tension, turn this screw over to the right. To decrease the
turn tha scrow over to the left,
Whtn tfc* tension on the b
is acorrect stitch can usu i-:e prepejrly adjusted, it Is seldom necessary
by varyimg the tension on the needle thread.

REGULATING THE
LENGTH OF THE STITGH
Tho length of the stitch is regu-
lated by the stkch-re,gulator and
thumb-screw in the slot in front of
iFig. 12 (A). Loosen the
move regulator down-
wards and the stitches will become
longer. If the regulator is moved
in the opposite direction (upwards)
the stitches become shorter. After
determining the correct position of
the regulator, re tighten the screw
imnediately so the position will
noi; be altered.
TO SEW IN REVERSE
LoAsen the screw and move ^ever
ab4ve center line, Fig. 12 (C). You
can now adjust for desired length
of
the
reverse stitch. Then tighten

HELPFUL HINtS
MACHINE WORKING HEAVILY: If, after standing idle for some time, the machine
works heavily, apply alittle paraffin or benzine in place of oil. Then run the machine
rapidly to clean the bearings with special sewing machine oil. The use of inferior oil
is often the cause of ilhe machine heavy working.
TO AVOID BREAKING NEEDLES: See thai: the presser foot or attachments are
securely fastened by the thumb screw. Do not sew heavy seams, or very thick goods
vvjth too fine aneedle. Alarge needle and thread to correspond should be used on
,fheavy work. See that the needle is not bent and avoid pulling when stitching.
BREAKING OF THE NEEDLE THREAD: If the needle thread
caused by:
•
•Tension being too tifcht.
•The needle thread being too coarse for size of needle.
•The needle being bent or set incorrectly.
SKIPPING OF STITCH: The needle r*ay be accurately set into che needle bar
or the needle may be bent or blunt. Th4 WNiB* may be toe small :ox the thread
being used.
•it •

OIL'NG OF THE MACHINE
To insure easy vanning, the machine requires oiling and if used continuously
it should be oil?d every day. One drop of oil in each hole is sufficient. Lift
machine back and oil all rroving parts on the underside of the machine.
