LUBRICATION AND CLEANING
Use SINGER* OIL, “TYPE B” or “TYPE D”. Use
“TYPE D” OIL when an oil is desired which will
produce minimum stain on fabrics.
A machine in continuous use should be oiled fre
quently. Frequency is dependent upon the speed at
which the machine is operated and the type of work
being done. Basically the machine needs oiling at
least twice each working day.
Before starting the machine, at the beginning of the
day and again after the midday recess, apply a few
drops of oil at each of the oiling points on the machine.
Arrows indicate oiling points in Figs. 2 through 5.
Never attempt to oil shuttle race (See Fig. 5) through
holes in throat plate.
BOBBIN WINDER LUBRICATION
Oil bobbin winder occasionally by applying a few
drops of oil to oil wick in bobbin winder frame, as
instructed in
Fig. 11, page 7.
CLEANING
Clean out all lint and abrasive matter from around
the shuttle and between the feed rows on the under
side of the throat plate.
Close all covers after oiling and cleaning. Wipe off
excess oil from surfaces of machine that may come in
contact with material.

THREAD
On Machines of Class 331K, 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 in Fig. 6. Then twirl the thread over toward you.
If the strands of the thread wind tighter, the thread is
left twist, if the strands unwind or separate, the thread
is right twist. Rough or uneven thread, or thread which
passes with difficulty through the eye of the needle,
will interfere with the successful use of the machine.
NEEDLES
The needle you select will have a very direct effect
on the quality, strength and appearance of the stitch
produced by the machine.
In selecting a needle size . . . the eye must be large
enough to allow the thread you are using to pass
through freely without binding or chafing. A simple
test is to thread a short length of thread through the
eye of the needle selected; hold the thread taut in a
vertical position and twirl the needle about the thread.
If the size is correct, the needle should slip down the
thread easily.
Needles for this machine are of Catalog #2055
(16 X 87) in Sizes 8 to 14, 16 to 19 and 21 to 25.

For best results always use SINGER needles.
TO SET THE NEEDLE
Turn the machine pulley over toward you until the
needle bar moves to its highest point.
After loosening needle clamping screw, remove old
needle and insert new needle UP into needle bar ASFAR AS IT WILL GO, as instructed in Fig. 7.
The single continuous groove of the needle MUST
face away from the shuttle point (toward the left end
of the machine, as shown in Fig. 7) with eye of needle
directly in line with arm of machine.
Securely tighten needle clamping screw.
Fig. 7. Setting the Needle
COMMON CAUSES OF STITCHING TROUBLES
Check needles often to make sure these defects are
not present...
^ Wrong needle for thread and material in use.
• Bent needle, clogged needle eye, or dirty
needle grooves may cause skipped stitches.
• Hook or burr on needle point may cause picking
or fraying of the material.
• Incorrect setting of needle.

UPPER THREADING
NOTE: Thread unwinder 225258 is recommended for
use with these machines.
First, turn the machine pulley over toward you until
needle is at its highest point, then pass the needle
thread from the unwinder through the threading points
in the order shown in Fig. 8.
Pass the thread from left to right through needle eye.
Draw about two inches of thread through the eye of
the needle with which to start sewing.
TO REMOVE THE BOBBIN
Turn machine pulley over toward you until needle
thread take-up lever is at highest point, as shown in
Fig. 8.
Reach beneath bed of machine with left hand and
remove bobbin from shuttle body, as instructed in
Fig. 9.
While latch is kept open, bobbin will be retained
in bobbin case.
To remove bobbin from bobbin case, release latch
and turn the open end of bobbin case downward.
Bobbin will drop out, as shown in Fig. 10.

Bobbin winder should be fastened to table with its
driving pulley approximately 1 /4 inch in front of the
machine belt. Bobbin winder driving pulley will then
make firm contact with machine belt when thumb latch
is pressed down. Bobbin winder pulley will be released
from contact with belt when sufficient thread has been
wound upon the bobbin.
Place bobbin on spindle, pushing it on as far as it
will go and pass thread through threading points, as
shown in Fig. 11.
Wind end of thread around the bobbin a few times
in the direction shown in Fig. 11. Press down on thumb

Fig. 17. Perfect Stitch
TO PREPARE FOR SEWING
Hold slack end of needle thread loosely and turn
machine pulley over toward you until needle moves
down and up again to its highest point, catching bobbin
thread.
• Draw up needle thread; bobbin thread will come
up with it through hole in throat plate, as shown in
Fig. 16.
• Lay both threads back under presser foot.
• Close the bed slide.
• Always keep the bed slide closed when the
machine is in operation.
TO START SEWING
• Move take-up lever to top of its stroke as shown
in Fig. 8, page 6.
• Place material beneath the presser foot. Lower
the presser foot. Start to sew, turning the machine pulley
over toward you.
TO TURN A CORNER
• Stop the machine when needle is rising but before
it is out of the material.
• Raise the presser foot.
• Turn material for next line of stitching, using needle
as a pivot.
• Lower the presser foot.
• Resume sewing.
• Avoid aiding the machine by pulling the fabric,
lest you damage the needle. The machine feeds the
work without assistance.
Fig. 18. Too Tight Needle Thread Tension
TO REMOVE THE WORK
• Stop the machine with the take-up lever at top of
its stroke.
• Raise the presser foot.
• Draw the work toward the rear until it is clear of
the needle.
• Cut the threads close to the goods.
• Lay the threads back under the presser foot.
THREAD TENSION
For ordinary stitching, tension on needle and bob
bin threads should be balanced with needle and
bobbin threads locked in centre of thickness of
material as shown in Fig. 17.
When there is too much tension on needle thread and
not enough on bobbin thread, needle thread cannot be
pulled down into material, as required. Poor stitching
results.
Needle thread will lie on top of material as
shown in Fig. 18.
When there is too much tension on bobbin thread and
not enough on needle thread, you get the reverse of
the condition shown in Fig. 18. The stitching is just as
poor. The bobbin thread will lie on bottom of material as shown in Fig. 19.
Page 9
REGULATION
BOBBIN THREAD TENSION:
For average sewing, tension on bobbin thread should
be very light.
To regulate tension on bobbin thread, remove the
bobbin case and turn screw in tension spring, as in
structed in Fig. 20.
^When tension on bobbin thread has been correctlyadjusted for ordinary stitching, the required stitch
can usually be obtained thereafter to suit the work in
process by varying the tension on needle thread
only.
NEEDLE THREAD TENSION:
To avoid accumulating excessive tension on needle
thread, first obtain correct tension on bobbin thread, as
instructed above.
Regulate needle thread tension only when
presser foot is down (since needle thread tension is automatically released when presser foot is raised).
Fig. 20. Regulating Bobbin Thread Tension
Tension on needle thread should be just enough to
set stitch correctly in material.
Having lowered presser foot, turn thumb nut at the
front of tension discs either over toward right or left, as
required. See instructions in Fig. 21.
PRESSURE OF PRESSER FOOT
ON THE MATERIAL:
The correct presser foot pressure helps feed the
work efficiently. You can regulate the amount of pres
sure exerted by the presser foot on the material by
means of the thumb screw, as shown in
Fig. 22.
The pressure on the material should be as light as
possible, while sufficient to insure correct feeding.
To increase the pressure turn the thumb screw down
ward.
To reduce the pressure turn this screw upward.
The pressure is correct when the work moves steadily
and smoothly without stalling.

REGULATION
LENGTH OF STITCH, ON MACHINE 331K1:
The length of stitch is regulated by moving the
pointer in the stitch indicator plate on the front of the
machine as instructed in Fig. 23.
When pointer is set at 0 there can be no feeding
motion.
Maximum length of stitch is 5Vb stitches per inch.
Move pointer to desired length of stitch and firmly
tighten thumb screw.
LENGTH OF STITCH, ON MACHINE 331K4:
Depress the feed-reversing lever slightly and turn
thumb screw over to the left to lengthen the stitch or over
to the right to shorten the stitch, as instructed in Fig. 24.

When thumb screw is set at “0” feed reversing lever
is fixed at central position and there can be no forward
or reverse feeding.
When thumb screw is set at “5”, machine will feed at
maximum stitch length.
REVERSE FEED, ON MACHINE 331K4:
(See instructions in Fig. 25)
Simply depress the feed-reversing lever as far as it
will go.
Feeding in reverse continues only as long as lever is
held in depressed position.
Forward feeding is resumed upon release of lever.
Direction of feed can be reversed at any point in a
seam while machine is in operation, without disturbing
the work. Back tacking is therefore readily accom
plished and ends of seams are easily fastened.
The range of movement of feed reversing lever is
limited by the setting of thumb screw as instructed
above under stitch length regulation.
When lever is released it will rise to highest point
permitted by setting of thumb screw and machine will
stitch forward at the set stitch length.

When lever is depressed as far as permitted by the
thumb screw setting, machine will feed in reverse at the
set stitch length.

THE STOP MOTION DEVICE
Machine 331K1 and 331K4 are regularly fitted
with solid disc (balanced) machine pulley 139724^
without stop motion device.
When required for treadle operation a machine may
be obtained, on specific order, with machine pulley
139725, including a stop motion device, as shown in
Fig. 26.
This device allows machine pulley to turn without
turning arm shaft so that bobbins ma/ be wound and
correct treadling acquired without disturbing the
stitching mechanism.
To loosen the machine pulley, hold pulley with left
hand and, with right hand, turn the stop motion screw
over toward you, as shown in Fig. 26.

Fig. 26. Loosening Machine Pulley
TREADLING
To acquire correct treadling habits, loosen the
machine pulley, as instructed in Fig. 26 and place both
feet squarely but comfortable upon treadle, as instruct
ed in Fig. 27.
Turn machine pulley over toward you by hand and
at the same time, allow your feet to move freely and
lightly with motion of the treadle.
Continue to do this until a regular, easy movement is
acquired and you are able to stop and restart the
machine without the machine pulley turning in
the wrong direction.
Tighten the stop motion screw and practice sewing
until you have become accustomed to the necessary
motion of hands and feet during the actual operation.

• Height of presser foot above throat plate 5/16
inch.
• Distance from throat plate seat to needle stop in
needle bar (needle bar at lowest point), 1.004 inches.
• Needle bar stroke 1.472 inches
• Rise of needle bar when point of shuttle is at
center of needle (loop lift), .100 inch.
VARIATIONS: Certain conditions of sewing may
necessitate slight variations from thèse settings.
TO SET THE PRESSER BAR
AT THE CORRECT HEIGHT
PREPARATION:
Remove face plate and slide plate.
Accumulation of lint, oil and dirt on presser foot seat
on presser bar may prevent proper seating of foot.
Clean this area before checking and setting the
presser bar.
CHECK:
1. When presser foot is raised with presser bar lifting
lever there should be a 5/16 inch clearance between
presser foot and throat plate.
2. When presser foot rests firmly upon throat plate
(with feed dog below throat plate) there should still be
some clearance between guide bracket A, Fig. 28 and
lifting bracket B, as shown in Fig. 28.
Fig. 28. Checking Height of Presser Bar
3. When presser foot is at its highest point and needle
bar is at its lowest, top of presser foot should clear the
needle thread eyelet C, Fig. 28 at the lower end of
needle bar.
SETTING:
• Release the presser bar lifting lever D, Fig. 28,
lowering the presser foot.
• Loosen clamping screw E, Fig. 28.
• Raise or lower guide bracket A, as required.
• Make certain presser bar is positioned correctly
so that needle will locate centrally between the two
toes of the presser foot.
• Securely tighten screw E.
Whenever guide bracket A, Fig. 28 has been
moved on presser bar, check the setting of check
spring as instructed on page 14.

I
ALTERNATE CHECK:
The gauge distance from throat plate seat to needle
stop in needle bar (at lowest point) should be 1.004
inches, as indicated in Fig. 30.
SETTING:
Loosen clamping screw F, Fig. 30. Raise or lower
needle bar, as required. Then securely tighten screw F.
Replace throat plate, slide plate and face plate.
TO TIME THE SHUTTLE
EXPLANATION:
Timing of shuttle is fixed at the factory for normal
sewing conditions at a 1/10 inch loop lift.
This is accomplished by pinning the shuttle driver at
one end of the oscillating shaft and then pinning crank
G, Fig. 31
at the other end of the shaft at the specified
timing location.
TO CHECK THE TIMING:
Turn the machine pulley over toward you until needle
bar descends to lowest point and then rises approxi
mately 1/10 inch.
At this setting, for normal sewing, the point of the
shuttle should be at the centre of the needle as shown
in Fig. 29.
Fig. 29. Relationship of Shuttle Point to Needle Eye

HEIGHT SETTING
PREPARATION:
Thread the machine.
CHECK:
Turn machine pulley over toward you slowly. When
take-up lever begins to rise^ spring K, Fig. 32 “checks”,
showing a slight dip and a return to its highest position.
Later, as take-up lever approaches top of stroke,
setting the stitch, this “check” spring K should be drawn
all the way down. As lever descends, check spring K
returns to rest.
TO SET THE CHECK SPRING
SETTING:
To obtain the slight dip in check spring when take-up
begins to rise, loosen screw L, Fig. 32. Turn stud M,Fig. 32 (at the same time turning entire tension as
sembly) either over toward left to lower the spring’s
resting position and decrease its movement, or
over toward right to raise the spring’s resting
position and increase its movement. Securely tighten
set screw L.
Fig. 33. Adjusting Tension on Check Spring
VARIATIONS (FOR MACHINE 331K4):
Under certain conditions of tacking, it may be neces
sary to set the check spring higher than it is otherwise
normally set.
TENSION SETTING
PREPARATION:
Thread the machine. Securely tighten set screw L,
Fig. 33. Make certain thumb nut is on stud M, Fig. 33.
CHECK:
Tension on check spring K, Fig. 33, should be suffi
cient to ensure action at top speed; but still light
enough to permit itself to be drawn all the way down
before any thread is drawn through the tension discs,
as take-up lever approaches height of stroke.
Check spring setting should be reviewed each time a
different foot is applied to machine.
SETTING:
Using a large screwdriver in slot of stud M, turn stud
either over toward left to decrease tension or over
toward right in increase it, as shown in Fig. 33.
VARIATIONS:
The tension on the check spring may require a
different setting, depending upon the thread and
material used. Heavier thread or bulkier material re
quires more tension to ensure correct thread control.
Page 15
TO TIME THE FEED
CHECK:
Test feed assembly linkage for freedom of move
ment. Action of feed dog must be regular and smooth
for maximum efficiency
15
When the feeding movement is correctly timed
• The feed dog stops moving toward the rear
just as the take-up lever reaches the top of its stroke.
• The feed dog drops below surface of throat
plate just as needle is about to enter material.
TIMING:
• Set the machine for longest stitch as instructed on
page 10.
• Turn up the cover plate at the rear of the machine
arm.
• Loosen set screw N in feed eccentric P, Fig. 34.
