THE Singer Electric No. 20-2 machine is a
practical, convenient sewing machine made
especially for children. It is simple and safe to
operate and will do real sewing on dolly's
wardrobe, or even on repairs to the grown-
ups' clothing and other household articles.
All the electrical parts of the motor are com-
pletely inclosed in the bakelite shell, so that
there is no danger of electrical shock. The
motor requires no attention, except occasion-
al oiling. It must be used only on 110 volt, 60
cycle, alternating current (A.C.).

To Start the Motor
Place the plug on the rubber-covered cord
into a wall outlet or light socket. (Be sure that
your currently is 110 volt, 60 cycle).
Press down on the switch (R, Fig. 2)
and the lever (S) at the same time; this will ill
start the motor. Release the lever, and the
rubber roller back of the hand wheel will
touch the rim of the wheel and drive the
machine.
To Stop the Motor
Push down on the switch (R), the same as for
starting. When through sewing, pull the plug
out of the electric outlet, and wrap the cord
around the machine.
Do not run the machine
or motor except when sewing.
To Change the Speed
Two sewing speeds are provided; a slower
speed for careful work, or for young children,
and a faster speed for ordinary straight work.
To change to a different speed, remove the
guard (X, Fig. 3) over the motor pulley by
pressing it downward and sliding it back.
For the slow speed, move the belt to the out-
side grooves (V) in the two pulleys, as shown
in Fig. 3. For the faster speed, move the belt
to the inner grooves (W) in the pulleys. Be
careful not to stretch the belt.
Then replace the guard with it two slots over
the metal tabs in the base, press it down and
forward into place.
If the motor stalls or the rubber roller slips on
the hand wheel, it is because the work being
sewn is to heavy for the machine.
If the rubber roller or the rubber belt should
slip when doing ordinary sewing, they may
have become hard and brittle with age and
should be replaced.

Needles and Thread
Needles for the Machine No. 20-2 are of Class and Variety 21x1 and four of these needles of
size 14 are furnished with each machine. Finer or coarser needles, as shown below, can be
purchased from any Singer shop or Singer salesman.
The size of the needle to be used should be determined by the size of the thread, which must
pass freely through the eye of the needle to ensure the successful use of the machine.

To Insert a Needle
Turn the hand wheel (Q, Fig. 2) over from
you until the needle bar (M, Fig. 2) moves up
to its highest point. With the screwdriver,
loosen the set screw (G Fig. 2) in the lower
end of the needle bar, take out the old needle
and put the new needle up into the bar as far
as it will go, with its flat side toward the right
and the long groove in the needle at the left,
then firmly tighten the set screw (G).
To Thread the Needle
(SEE FIG. 4)
Turn the hand wheel over away from you until
the needle moves up to its highest point.
Place the spool of thread on the spool pin,
pass the thread from the spool toward you
through the two holes (! and 2) in the thread
pull-off, to the left and down through the hole
(3) in the nipper lever. Draw the thread to the
left under the end of the nipper lever and
pass it over between the tension discs (4), up
though the hole (5) in the machine, from right
to left through the hole (6) near the upper end
of the needle bar, down and from left to right
through the eye of the needle. Draw about
two inches of thread through the eye of the
needle with which to commence sewing.
To Commence Sewing
Raise the presser foot (E Fig 2) by turning up
the presser bar lifter (K, Fig 2). Place the
material beneath the presser foot and lower
the presser foot. Lay the forefinger of the left
hand gently on the end of the thread and turn
the hand wheel (Q, Fig. 2) over from you in
the direction indicated by the two arrows on
the hand wheel, until the first stitch is made.
Then place the end of the thread back under
the presser foot and commence to sew.

To Remove the Work
Sew two stitches past the end of the seam
and stop the machine with the needle bar at
its highest point, then with the left hand draw
a finger length of thread to the left through
the hole near the upper end of the needle bar
as shown in Fig. 5. With the right hand,
using a pair of scissors, draw the slack thread
to the right through the eye of the needle, as
shown in Fig. 6, then pull the thread upward
from the work, the presser foot being down,
and cut the thread close to the goods, as
shown in Fig. 7. Raise the presser foot, pull
the work from you and the end of the thread
will be draw through the loop, as shown in
Fig. 8.

To Fasten Off the Stitching in the Work
When it is necessary to fasten off the last
stitch in the work, stop the machine with the
needle in the work, place the fingers on the
material close to the presser foot to prevent
the work from moving, raise the presser foot
and take one more stitch in the last hole
made and stop the machine with needle bar
at its highest point; then with the left hand
draw a finger length of thread to the left
through the hole near the upper end of the
needle bar as shown in Fig. 5. With the right
hand, using a pair of scissors, draw the slack
thread to the right through the eye of the nee-
dle as shown in Fig. 6; then pull the thread
upward from the work and cut the thread
close to the goods as shown in Fig. 7. Pull
the work from you and the end of the thread
will be draw through the loop as shown in
Fig. 9.
To Change the Length of Stitch
The length of stitch is regulated by the same
lever (A, Fig. 2) under the cloth plate. To
make a longer stitch, move this lever away
from you. To make a shorter stitch, move the
lever toward you.

THE END OF A SEAM
FIG 9. STITCHING FASTENED OFF IN THE WORK
To Regulate the Tension on the Thread
The tension on the thread is automatic and
seldom requires changing. When the needle
is at its highest point, the nipper lever (3, Fig.
4) is raised and the tension on the thread is
released so as to allow the needle bar to
draw off sufficient thread for the next stitch. If
the stitches are so tight that they pucker the
material, loosen the tension by turning to the
left the thumb nut (O, Fig. 2) at the front of
the tension discs. If the stitch is too loose,
tighten the tension by turning the thumb nut
to the right.

To Use the Cloth Guide
To guide the work accurately when sewing
close to the edge of the goods, the cloth
guide (H, Fig. 2) should be used. Fasten the
cloth guide to the cloth plate of the machine
by means of the clamping thumb screw (J,
Fig. 2), inserting the thumb screw into the
screw hole in the cloth plate. The cloth guide
can be adjusted to bring the edge of the
goods as close to the line of stitching as
desired. If desired, the cloth guide can be
removed from the machine.
To Oil the Machine
The machine should be oiled occasionally
with the sewing machine oil especially pre-
pare by the Singer Sewing Machine
Company. This oil can be purchased from
any Singer shop or Singer salesman. Apply
one drop of oil at each of the places where a
part of the machine moves against another
part.
About every six months, put a drop or two of
CAUTION
Do not run the machine or motor except
when sewing.
When the machine is not in use, always
remove the plug from the electric outlet or
light socket.
Further Instructions
for the use of this machine or any other
Singer Machine, will be cheerfully given at
your local Singer Shop.
