SINGER
introducing the New SINGER*Sewing Machine Model 591!
The most dependable, lightest running machine of its kind. This
machine will
produce top quality straight-line single-needle lock stitch
ing in fabrics as fine as ladies' lingerie or as heavy as men's overcoating.
With an oil reservoir, a pump and a minimum of wicking, all parts
requiring oil are kept constantly lubricated. Oil flow can be checked
easily through a "window" on arm top cover.
Quiet and smooth in operation, the Model 591 was designed for your
comfort, making sewing more pleasant, quicker and more profitable
to you.

OILING THE MACHINE
Oil your machine! For best results, use SINGER*TYPE "A" or "C"
Oil. TYPE "C" Oil is used when an oil is desired which will produce
minimum staining of fabrics even after along period of storage.
TIP MACHINE BACK

FILL TO HIGH MARK
NEVER ALLOWOILTO FALL
BELOW LOW MARK
Tip machine back on its hinges and fill the oil reservoir as illustrated in
Fig. 2.
When a machine is NEW or has been idle for several weeks, it is advisa
ble to oil the needle bar, take-up bearings, and all other parts which are
in movable contact. The automatic lubricating system will function ef
ficiently after running the machine at 2500 to 3000 revolutions per
minute for 10 to 15 minutes and continue to lubricate all bearings.
CAUTION: Correct lubrication is indicated by a continuous stream of
oil passing the oil flow window while machine is running, as shown in
Fig. 3.
Should this oil flow become erratic,
STOP the machine and check the
reservoir oil level. Fill if needed.
At least twice each month, check
the oil level in the reservoir. Never
allow the oil level to drop below
LOW mark, shown in Fig. 2.

NEEDLES
The needles you use have a very direct effect on the quality, strength
and
appearance of the stitching produced by your machine. This iswhy
it is so important to
use SINGER needles according to the following
chart.

Note:
Needles for 591D305A. Use catalog number 1515 and corresponding
needle
bar for the 1/16" and 3/32" trim margins.
A bent needle will cause your machine to skip stitches and drift away
from a desired sewing direction.
A hook or burr on the needle point will result in a blurred finish and
may cut the material.
THREAD
In the Class 591, use ONLY left twist thread in the needle. Either
right or left twist thread can be used in the bobbin. To determine the
thread twist, hold the thread as shown below. Then roll the thread held
by the right hand over toward you —if the strandsof the thread wind
tighter, the thread is left twist; if the strands unwind or separate, the
thread is right twist.

INSERTING THE NEEDLE
Turn the machine pulley over
toward the operator until the
needle bar moves to its highest
point.
After loosening the needle clamping
screw, insert needle UP into needle
bar AS FAR AS IT WILL GO, as
instructed in Fig. 6.
The long groove of the needle
MUST face the left end of the
machine, as shown in Fig. 6.
Securely tighten the needle clamp
ing screw.
THREADING THE MACHINE
First, turn machine pulley over
toward you until needle is at its
highest point, then pass the needle
thread from the thread stand
through the threding points in the
order shown in Fig. 7, with the
exception of 591C200A and 591C-
300A machines.
For threading the 591C200A and
591C300A machines, see Fig. 8.
Draw about two inches of thread
through the eye of needle with
which to start sewing.

WINDING THE BOBBIN
Fig. 10
Place bobbin on spindle A of bobbin winder pushing it on as far as it
will go and pass thread from the thread stand through threading points
as shown in Fig. 10.
Wind end of thread around the bobbin a few times. Press latch B against
bobbin, pushing driving pulley over against machine pulley, then start
the machine.
The bobbin winder will stop automatically when the amount of thread
for which it is regulated is wound upon the bobbin. For more thread
on bobbin, loosen screw C and swing latch Baway from you: for less
thread on bobbin, swing latch B toward you. Tighten screw C
When winding a bobbin with fine thread, alight tension should be used.
Adjust the knurled nut D, Fig. 10, to regulate the tension.
If thread winds unevenly on bobbin, loosen set screw holding pre-ten-
sion
stud E and move tension bracket up or down, as required. Tighten
the set screw.
Bobbins can be wound while the machine is stitching.
Note: It is recommended that winding of bobbin be held to approxi
mately 80% of its winding capacity. Also, do not use too much tension
on the thread when winding since too tight thread tension may cause
deformation of the bobbin and result in damaging the needle.

PREPARING TO SEW
Hold end of needle thread with left
hand very lightly. Then turn the
machine pulley over toward you
slowly until the needle moves down
and up. Pull on the needle thread
and the bobbin thread will come up
through the hole in the throat plate
as shown in Fig. 14. Place both
threads under the presser foot prior
to sewing.
SEWING
Place the material under the pres
ser foot and lower the presser foot.
You are now ready to sew — quick
ly, smoothly and easily.
Stop the machine when the needle
bar has just started to come down
for best material removal. Raise the
presser foot, draw the work behind
the presser foot and cut the threads
close to the work.

SETTING THREAD TENSIONS
Normally, tension on the needle
and bobbin threads should be
balanced so that if you were to
look at a cross section of a line of
stitching, the needle and bobbin
threads would be locked in the
center of the thickness of the ma
terial as shown in Fig. 15-A. Incor
rect settings will produce the condi
tions as shown in Figs. 15-B and 15-
C.
Regulate the needle thread tension
as shown in Fig. 16. Be sure the
presser foot is down when making
tension adjustments.
Tension on the needle thread
should be just enough to set the
stitch properly in the material. See
Fig. 15-A.
For average sewing, the tension on
the bobbin thread should be very
light.
Should regulation of the tension on
the bobbin thread be necessary, re
move the bobbin case and adjust
as shown in Fig. 17.
From the library of: Superior Sewing Machine & Supply LLC

ADJUSTING THE TAKE-UP SPRING
The tension and the range of move
ment of the take-up spring A may
require different settings depending
upon the size of thread and materi
al used. Heavier thread or material
require more tension; delicate
materials require less tension. Also
the movement of take-up spring
should be increased to ensure cor
rect thread control.
Using a large screwdriver in slot of
stud B, turn stud either over
toward left to decrease tension, or
over to right to increase tension, as
shown in Fig. 18.
To set the take-up spring height,
loosen screw C(Fig. 19) and turn
entire tension assembly either over
toward left to lower take-up spring
and decrease its movement, or over
toward right to raise take-up spring
and increase its movement. Secure
ly tighten screw C.
