How to Use Attachments
How to Embroider with a Hoop
It is easy to follow a stamped design or to work free hand
when embroidering or monogramming. (See Figs 16 and l7.(
Release the pressure from the foot by turning the burled nut
on the automatic darner in the direction of the arrow, or
clockwise. Push the drop feed button down so that “E”
appears between the two buttons. Stretch the fabric in an
embroidery hoop, and place under the needle after removing
the presser foot. Set the stitch width at the size you prefer
and lower the presser bar lifter. Then operate the machine
at a rather high speed while moving the hoop slowly with
both hands. Work carefully and be sure to keep fingers out
of the path of the needle.

(Fig. 18A)
1. Narrow hemmer. With the needle in its highest position
replace regular presser foot with narrow hemmer Fig 18 A.
For a plain narrow hem, make a I 8 inch double fold for about
two inches along edge of fabric. Hold each end of the two-inch
fold, slip underneath hemmer. Bring fold up into the scroll of
hemmer, draw forward to end and fasten with point of needle.
Lower presser bar lifter. Gently pull ends of thread as you
start stitching.
Guide material slightly to right, and it will automatically take
a double turn through scroll.

Fig. 18 C,
Lace Trimmed hem
To attach lace to hem, insert lace in the slot next to
needle. Sew hem as above, guiding lace under needle
and hem into scroll Fig 18 B
Lace Edge with Invisible Stitching
Hold lace I 8 inch from raw edge on right side of
fabric. Insert both in scroll as for plain narrow bern.
Let hem roll over and sew in lace. Press lace out flat
along edge with hem turned up. For a little fullness
in lace, feed it freely under scroll.
French Seam
(Fig. 38 B
With right sides together, place top piece of material
1 8 inch inside edge of lower piece.
Insert in hemmer scroll, allowing hem to roll over and
sew in top fabric, making French seam Fig 18 C.
Flat Felled Seam
Open out French seam and insert rolled edge in scroll
of hemmer. Edgestitch to lay seam flat.
2. Quilting Guide. This guide for making par
allel rows of stitching is attached by placing the pron
ged holder between the presser foot and the presser
foot clamp screw Fig 113 .
Adjust
the curved bar to
press lightly on the fabric. By letting the guide ride
on the first stitching line, successive rows will be an
equal distance apart. When the bar is attached so
that the curved part is to the right of the needle, it
may also serve as a seam width guide.

(Fig. 20)
3. Seam Gauge. Fasten gauge with screw provided in one
of threaded holes in the machine bed next to the needle plate.
Adjust to the seam width preferred by sliding the slot of the
gauge along the screw before tightening. Guide fabric so
edge just touches flat surface on seam gauge. See Fig 20.
(12 )

4. Sewing on Buttons. Exchange the regular presser foot for the one provided to sew
on buttons. See Fig 21. Drop the feed to “E position. Place button and fabric under
presser foot. Determine the width of the stitch needed to enter each hole of the button by
turning the hand wheel slowly toward you as you adjust the zigzag regulating knob. Then
lock at that width. Take six or seven stitches to fasten the button securely. Then turn the
knob to 0 and take two or three more stitches in one hole to lock the threads. Repeat the
procedure when sewing on four-hole buttons.
Snaps and hooks may be stitched on in the same manner.

with the buttonhole foot which is equipped with a measurement
gauge (Fig 22. Set the stitch length near 0 for a very short
stitch. The width of the stitch should be set at 2 or slightly
under for a daintier buttonhole. If a heavier buttonhole is
required, cord may be strung through the hole in the foot.
Mark the desired length of buttonhole on the fabric or set the
gauge so that the distance between the curved marker and the
needle is equal to that of the buttonhole. Sew the first side
of the buttonhole, stopping the machine with the needle in the
material at right side of stitching.
Drop the feed to “Eu position and turn zigzag knob to No 4
width. Take about five or six stitches to make a bar tack.
Stop the machine with the needle out of the fabric, but leave
the presser foot down. Raise the feed to “N” and return
stitch width to 2 or original setting.
Proceed to stitch the second side of the buttonhole. When
you have reached the end of the first row of stitching, stop
the machine again with the needle out of the fabric,
(Fig. 22)
Lift the presser foot, and using the needle as a pivot, turn the
fabric end for end or 180 degrees (see Fig 23). Before lowering
the presser foot make sure that the first row of stitching is
lined up straight. Lower presser foot and turn wheel by hand
just enough to raise needle out of fabric.
(14 )

Leave the presser foot down, drop the feed to “E”, turn Zigzag knob to No.- width, and take five
or six stitches to close the buttonhole. Stop the machine with the needle out of the fabric, but do not
raise the foot.
Return stitch width to () and take two or three stitches, which will fasten the bar threads and prevent
ravelling.
Cut the buttonhole opening with the seam ripper, being careful not to cut the stitching.
If you plan to make buttonholes on sheer or soft material, place tarlatan or paper, which can be torn
away after stitching, under the fabric. And it is always wise to make several buttonholes on scraps
of fabric before working on the garment.

Check Up for Smooth Sewing
Although your sewing machine is designed for maximum efficiency, should any of the following difficulties occur
they can be remedied with minor adjustments,
Upper Thread Breaks.
Be sure needle is inserted properly.
Check on correct way to thread machine.
Use correct needle size for thread.
Do not have upper tension too tight.
Lower Thread Breaks
Check correct method of threading bobbin case.
Be sure lower tension is not too tight.
Needle Breaks
Do not tug or pull on the fabric while sewing as this will bend and eventually break the needle.
Skipped Stitches
Stitches Loop
Do not use a blunt or bent needle.
Insert needle correctly.
Use correct needle size for thread.
Be sure pressure on foot is sufficient when sewing heavy fabrics.
Make sure tensions are properly balanced and that machine is threaded correctly.
Machine Binds
Clean thread, dust and lint from hook, shuttle and race. If condition continues, it may be that the machine
is gummy with oil. Apply kerosene to oil holes, run rapidly for a while, and wipe dry. Then lubricate
again with fine sewing machine oil.
( 25

Oiling and Cleaning
Before starting to oil the upper part of the machine, turn hand wheel
until take-up is at its lowest point. Apply a drop of oil to points
indicated by arrows in Figs 43, 44 and 45.
(Fig. 43)
To reach the areas requiring oil on the underside
of the machine (Fig 44( tilt the head back on
its hinges.
How frequently the machine is used determines the oiling
requirements. Moderate use calls for only an occasional
oiling. After applying the oil, run the machine at high
speed so that all parts will be penetrated by the oil.
