DESCRIPTION
These SINGER family sewing machines will give
you practically life-time service.
Machine 15-88 is intended for operation by foot
power and is regularly equipped with a treadle stand.
Machine 15-89 has a hand driving attachment
and is provided with a wooden base and cover. This
portable outfit can be conveniently carried from
place to place as desired.
Each machine has an oscillating shuttle on a hori
zontal axis and makes the lock stitch. Both machines
have 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 each
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.

TO REMOVE THE BOBBIN
Raise the take-up lever 5, Fig. 6 to its highest point.
Withdraw the bed slide plate. Reach down with
the left hand and open the bobbin case latch M and
lift out the bobbin case. Release the latch and re
move the bobbin from the bobbin case.

TO WIND THE BOBBIN
(See Fig. 8 on the Following Page)
Hold the balance wheel D with the left hand and,
with the right hand, loosen the stop motion screw E
to release the balance wheel from the stitching
mechanism.
Place the bobbin on the bobbin winder spindle as
far as it will go, having the small pin enter the
hole in the side of the bobbin.

Place the spool of thread on the spool pin 1
Pass the thread to the right between the tension
discs 2
Up and to the left through one of the holes in the
left side of the bobbin 3, from the inside.
Fig. 8. Winding the Bobbin
The end of the thread must be held by the hand
until a few coils are wound and then should be
broken off.
Press down on the bobbin and the bobbin winder
latch will drop down and hold the bobbin winder
pulley against the hub of the balance wheel.
Then operate the machine the same as for sewing.
When sufficient thread has been wound upon the
bobbin, the bobbin winder is automatically released
from the balance wheel.
Then tighten the stop motion screw E.
12
If the pressure of the bobbin winder pulley against
the hub of the balance wheel is insufficient for wind
ing the bobbin, press down the bobbin winder until
the latch N, Fig. 9 drops down and holds it, then
loosen the adjusting screw O, Fig. 9. With the fore
finger, push back the upper end of the slotted plate
P as far as it will go, as shown in Fig. 9, and at the
same time press the bobbin winder pulley against
the hub of the balance wheel, then tighten the
adjusting screw O.

Fig. 9. Adjustment of Bobbin Windek
If the thread does not wind evenly on the bobbin,
loosen the screw which holds the tension bracket
2, Fig. 8 in position on the bed of the machine and
slide the tension bracket to the right or left, as may
be required, then tighten the screw.
Bobbins can also be wound while the machine
is sewing.
TO THREAD THE BOBBIN CASE
Hold the
bobbin so that
the thread will
unwind in the
direction
shown in
13
Fig. 10.

Fig. 10
Hold the bobbin
case as shown in
Fig. 10, and place
the bobbin into it.
Pull the thread into
the slot 1, under the
tension spring 2 and
into the slot 3 at the
end of the spring.
14
TO REPLACE THE BOBBIN CASE
Hold the bobbin case by the latch and place it
on the stud T of the shuttle body with the position
finger S opposite the notch at the top of the shuttle
race.
£19096
Fig. 13. Bobbin Case Threaded and Replaced
Release the latch and press the bobbin case back
until the latch enters the groove in the stud. Allow
about three inches of thread to hang free from the
bobbin case and close the bed slide plate.
TO PREPARE FOR SEWING
Hold the end of the
needle thread with the
left hand and turn
the balance wheel
over toward you
until the needle goes
down and up again and
the thread take-up
lever 5, Fig. 16 is at its
highest point. Pull up
the needle thread and
15
bobbin thread will come
with it, as shown in
Fig. 14.
Fig. 15
Threads in Position to
Commence Sewing
Fig. 14
Drawing Up the Bobbin Threat
Lay both threads back
under the presser foot diag
onally across the feed, as
shown in Fig. 15, to the right
or left, depending upon
which side of the needle the
material is to be located, so
that when the presser foot
is lowered, the threads will
be firmly held between the
feed and the presser foot.
TO COMMENCE SEWING
Be sure to have the
thread take-up lever
5 at its highest point.
Place the material
beneath the presser
foot B, lower the foot
by means of the presser
bar lifter C and com
mence to sew, turning
16
the balance wheel over
toward you.
Never pull the ma
terial along when
stitching. This is liable
to bend the needle.
Guide the material only.
Never operate the
machine without cloth
under presser foot.
Fig, 16
The slide over the bobbin case should be kept
closed when the machine is in operation.
The balance wheel must always turn over toward
the operator.
17
TO TURN A CORNER
Stop the machine when the needle is commencing
its upward stroke. Raise the presser foot and turn
the work as desired, using the needle as a pivot,
then lower the presser foot.
BASTING
The longest stitch, No. 6 on the stitch indicator,
adjusted by lever X, Fig. 17, is satisfactory
for basting. These basting stitches can be easily
removed by clipping every sixth stitch and with
drawing the long continuous thread.
Machine basting is firmer, more even and much
quicker than hand basting.
TO SEW BIAS SEAMS
Use a shorter stitch when sewing bias or curved
seams to increase the elasticity of the seam and
to prevent seam failure under strain.
No change in tensions is required.
TO REMOVE THE WORK
Stop the machine with the thread take-up lever
5, Fig. 16 at its highest position. Raise the presser
foot, draw the fabric back and to the left, and sever
the threads on the thread cutter U, Fig. 16. Place
the ends of the threads under the presser foot, as
shown in Fig. 15.
18
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.
Fig. 17. Showing Lever for Reversing Direction
OF Feed and Regulating Length of Stitch
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 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.
19
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 'Tack 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
upvrard.
