DESCRIPTION
This SINGER family sewing machine will give
you practically life-time service.
It is intended for operation by electricity, having
an electric motor built’ on the back of its arm, The
motor drives the machine through spiral gears.
It is also equipped with an electric SINGER-
LIGHT*.
The machine has an oscillating shuttle on a hori-
zontal axis and makes the lock stitch. It has reverse
feeding mechanism which enables you to sew either
in a forward or backward direction, making it easy
to back tack and to fasten the ends of seams.
In addition to plain sewing, a great variety of
pleasing effects such as hemming, binding, edge
stitching, shirring, ruffling, etc., can be produced
with the aid of the attachments furnished with the
machine. These attachments and other popular
SINGER Fashion Aids will enable you to obtain the
much desired tailored appearance of professionally-
made garments and to add new fashion touches or
finishes demanded by swiftly changing styles at a
fraction of the cost of ready-made garments.

ELECTRICAL INFORMATION
Motor
The SINGER electric motor, located at the back
of the machine, is regularly furnished for operation
on a direct current of 110-120 volts or on alternating
current of 110-120 volts, 25 to 75 cycles. Special
motors can be furnished for direct or alternating
current for any voltage between 50 and 250, and
for 32 volts direct current.
To Connect Machine to
Electric Service Line
Before connecting the machine to the electric ser-
vice line, be sure that the voltage and the number
of cycles stamped on the motor nameplate are with-
in the range marked on the electric meter installed
by the electric power company.
Push the terminal plug at one end of the electric
cord on the three-pin terminal block (see Fig. 2,
page 4) at the right of the machine and connect the
plug at the other end of the cord to an electric outlet.
CAUTION
When you have finished your sewing, always
disconnect the plug from the electric outlet.

TO REGULATE THE LENGTH OF STITCH
The machine is adjustable to make from 6 to 30
stitches per inch, as indicated by the numerals on
the stitch indicator plate W.
Ww
£19039
Fig. 17. SHowrne Lever ror Reverstne Direction
or Freep anp Reeuuatine Leneru or Strrcw
The number of stitches to the inch that the ma-
chine is set to make is indicated by the number
which is in line with the upper side of the stitch
regulating lever X.
To change the length of stitch, loosen the thumb
screw Y and move it to the bottom of the slot. Then
move the stitch regulating lever X until its upper
side is in line with the number of the desired length
of stitch. Now move the thumb screw Y until the
stitch regulating plate (inside) touches the lever X,
then tighten the thumb screw Y.
The machine will now make the indicated number
of stitches to the inch in either a forward or reverse
direction, depending on whether the lever X is at
its lowest or highest position.
21
TO REGULATE THE DIRECTION OF FEED
To feed the material from you, push down the
stitch regulating lever X, Fig. 17 as far as it will go.
To feed the material toward you, raise the stitch
regulating lever X as high as it will go.
The direction of feeding can be reversed at any
point of a seam without removing the work from
the machine,
: The reverse feed makes it easy to do ‘“‘back tack-
ing” and to fasten the ends of seams.
TO REGULATE PRESSURE ON
PRESSER FOOT
For ordinary sewing, the pressure of the presser
foot on the material seldom requires changing. Heavy
materials require more pressure than light weight
materials, The pressure should be only heavy enough
to prevent the material from rising with the needle
and to enable the feed to move the work along
evenly. To increase the pressure, turn the thumb
screw V, Fig. 16 clockwise or downward. To lighten
the pressure, turn the thumb screw so that it screws
upward.
SINGER Needles should be used
in SINGER Machines.

TO REGULATE THE
NEEDLE THREAD TENSION
The tension on the
needle thread can be
regulated only when
the presser foot is
down.
The numerals ‘‘0 to

21 indicate the dif-
ferent degrees of ten-
sion that can be
obtained. The num-
bers do not denote the
size of thread or ounces
of tension.
Fria, 21, Neepie THREAD TENSION

23
When the tension has been correctly set for aver-
age sewing, note the number at the indicator line Q,
so that the tension may be reset should it be altered
for special work or change in size of thread.
Toincrease the tension, turn the thumb screw A
gradually to the right (clockwise) until the required
tension is obtained. Each higher number denotes
increased tension.
To decrease the tension, turn the thumb screw
A gradually to the left (counter-clockwise) until the
required tension is obtained. Each lower number
denotes less tension.
TO REGULATE THE
BOBBIN THREAD TENSION
The tension on the bobbin thread is regulated by
the screw R, Fig. 11 in the tension spring on the
outside of the bobbin case. To increase the tension,
turn the screw R over to the right. To decrease
the tension, turn this screw 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.

stud, being sure that the lug M, Fig. 22 engages
the short recess P to prevent the plate from turn-
ing on the stud. Next, replace the two tension discs
H on the stud, having the flat thread-bearing sides
of the dises together. Replace the indicator G with
the large open side facing end of stud so that the
plus and minus signs will be readily seen from a
sewing position as shown in Fig. 23. Insert the ten-
sion spring F in the indicator so that the first half
turn F2 of this spring will straddle the lower half of
the tension stud. Guide the stop washer D onto the
stud so that the extension S will be above the ten-
sion stud as shown in Fig. 23.
NOTE: If the
spring and stop
washer are in cor-
rect position, the
extension S will

site the stop washer extension S, then push
the dial to compress the spring so that the
thumb nut can be turned onto the stud,
carefully guiding the pin in the thumb nut into
one of the holes in the numbered dial. Lower
the presser bar and turn the thumb nut A to the
left until it stops at “0.”? Thread the tension and
pull the thread through the tension dises to test the
amount of tension at the ‘“O”’ position. At this point
there should be a barely perceptible pull on the
thread to indicate that there is a minimum tension
which
gradually
increases
with
the
turn
of
the
thumb
nut
to
the
right,
providing
a
full
range
of
tensions
from light to heavy within one revolution of the
thumb nut. If the pull is too strong for a minimum
tension,
press
in
the
numbered
dial
to
disengage
the
pin in the thumb nut from the dial and reset the pin
in one of the holes to the left of the previous setting.
This resetting of the pin will produce less tension at
zero.
On
the
other
hand,
should
there
be
insufficient
tension
at
zero,
press
in
the
dial
and
reset
the
pin
in
one
of
the
holes
to
the
right
of
the
previous
set-
ting.
Repeat
this
process
until
the
desired
minimum
tension is obtained.
If Correct Stitching is Not Obtained:
If
the
bobbin
thread
tension
has
been
disturbed,
or
a correct
stitch
cannot
be
obtained
without
a
very
heavy
or
very
light
needle
thread
tension,
then
the
following
procedure
is recommended:
Using No. 50 thread in the needle and on the bob-
bin, adjust the needle thread tension as instructed
above. Then turn the tension thumb nut to‘3” and,
with two thicknesses of thin material in the machine,
adjust the bobbin thread tension, as instructed on
page 23, until the stitch is correctly locked in the
material as shown in Fig. 18.
A wide range of materials and threads can now
be accommodated without further adjustment of
the bobbin thread tension.

TO LUBRICATE THE MOTOR
NEVER USE OIL OR ORDINARY GREASE
FOR LUBRICATING THE MOTOR as they are
harmful for this purpose. USE ONLY SINGER
Moror Lusricant, a tube of which is supplied with
the machine. It is the only lubricant which will
positively lubricate the motor.
When the machine is shipped from the factory,
the two motor grease cups A, Fig. 29 are filled with
sufficient SINGER Moror Lusricanr for approx-
imately one year’s use. Refill these grease cups at
least once a year thereafter.
Turn the machine back on its hinges and remove
the two thumb screws from the two grease cups A
and clean out the interior of the cups. Then insert
the tip of the motor lubricant tube into the grease
cups as shown in Fig. 29, and while holding the tube
firmly against the -bottom of the grease cups,
squeeze enough grease into each cup to fill
them. Replace and tighten the thumb screws.

MULTI-SLOTTED BINDER
This multi-slotted binder will apply unfolded
bias binding +3 inch in widthand commercial folded
binding in sizes 1, 2, 3, 4 and 5 to the seams or to
the edges of garments. These sizes of folded binding
are 14, #:, 34, 7 and inch in width, respectively,
and are fed through slots of corresponding sizes in
the binder scroll. See Fig. 44. Binding may be
purchased in a variety of materials and colors.
For convenience in determining the correct width
of unfolded binding (43 inch), this measurement
is marked on the binder, as shown in Fig. 44.

The wide range of bindings that can be applied
with this binder makes it useful for a large variety
of work. It will be found particularly advantageous
for making children’s wear, lingerie, summer dresses,
and other dainty articles which call for the nar-
rower bindings.
46
As two different widths of binding of contrasting
color can be fed through the binder at the same
time, attractive binding and piping effects can be
produced in one operation.
To Attach the Binder
Raise the needle to its highest position, then at-
tach the binder to the presser bar in place of the
presser foot.
See that the needle enters the center of the
needle hole.
To Insert the Binding
In the Binder
Cut all binding to a long point
to the left, as shown in Fig. 45.
Folded bias binding must be
inserted in the slot or slots of cor-
responding sizes. See Fig. 48.
Unfolded or raw edge bias
binding must be inserted in the
open end of the scroll. See
Fig. 46.
After inserting the pointed end of the binding in
the binder, push it through until the full width of
the binding is under the needle.
Guide the binding by means of the two upright
pins, as shown in Figs. 46 and 48.

47
To Insert the Garment
in the Binder
Place the edge to be bound as far to the right as
it will go in the center slot of the scroll C2, as shown
in Fig. 46, and draw it back under the binder foot.
Fig. 46. Brnpine wits Unroipep Binpina
Lower the binder by means of the presser foot
lifter, and commence to sew. Keep the material
well within the center slot of the scroll so that the
edge will be caught in the binding.
To Adjust the Binder
To bring the inner edge of the binding closer to
the stitching, move the scroll C2, Fig. 46 to the
right by means of the lug B2, Fig. 46. This is
the usual adjustment when binding straight edges.
When binding curves, move the scroll to the left
to bring the inner edge of the binding farther from
the stitching and allow for the sweep of the curve.

A garment can be piped and bound in one opera-
tion, as shown in Fig. 48.
E18167B
Fig. 48. Prprne anp BinpinG IN ONE OPERATION
IMPORTANT: When piping and binding at the
same time, as shown above, insert the narrow width
of binding first in its slot, then insert the wider
width in its slot. Two consecutive widths should
not be used at the same time. That is, if No. 1
is used, the wider binding should not be smaller than
No. 3. If No. 2 is used, the wider binding should
not be less than No. 4. Never use Nos. 1 and 2,
or 2 and 3, etc., together.
Use the upright guide pins to guide the wider of
the two widths of binding, as shown in Fig. 48.

50
To Bind Outside Curves
Allow the edge to be bound to pass freely through
the scroll without crowding against the scroll wall.
The material must be guided from the back of the
binder and to the left, permitting unfinished edges
to swing naturally into the scroll of the binder.
