Apply this oil to oil filler cup on top of machine, pouring oil into reservoir until oil in the sight gauge is at “FULL” mark, as indicated in Fig. 4.

Check oil sight gouge daily before starting machine and oil machine, when necessary, as in structed in Fig. 4 above.

WHEN A MACHINE HAS BEEN IDLE FOR A CON

SIDERABLE TIME (OR AFTER A MAJOR INSTALLA

TION OF PARTS): Clean machine thoroughly. Then apply a few drops of oil to oil grooves of feed bar connections Q5 (see inset at bottom left of Fig. 4) and to looper carrier connection guide bar at

02, Fig. 5 behind upper knife carrier and chip guard. Apply a drop of oil to presser bar at

H5, Fig. 4. Check oil level in reservoir, as instructed in Fig. 4.

AFTER MACHINE IS

INSTALLED AND BEFORE

STARTING MACHINE:

Remove the chip guard from the front of the machine.

Check the oil flow on right hand looper carrier connection guide bar at 02, Fig. 5.

To adjust amount of oil flow on guide bar at

02, loosen lock nut D5 and turn adjusting screw

15, Fig. 5 clockwise as far as possible. Oil flow is now shut off, completely.

Back off screw 15 (turning screw anti-clock wise) 1/2 turn. Check lubrication again.

To increase oil flow, turn screw 15 anti-clock wise a small amount and recheck lubrication.

If oil flow is too great, turn screw L5 clockwise about 1/4 turn and recheck.

Never operate machine when oil flow is SHUT

OFF at 15.

When correct oil flow is obtained, lock the nut

D5, Fig. 5. Replace the chip guard.

Remove belt and check freeness of machine by turning machine pulley by hand. Replace belt.

Finally, “run-in” the machine for approximately

15 minutes at a moderate speed.

Maximum speed recommended for these ma chines is 5500 stitches to the minute.

5000 stitches to the minute is recommended for long runs or while sewing long stitches.

Maximum efficient speed is dependent upon the nature of the operation, the ability of the operator and the type of material being sewn.

SPEED

It is advisable to operate these machines at more moderate speeds the first few days, after which they can be run at tap speed.

When the machine is in operation, top of ma chine pulley must always turn over away from operator.

Needles are of curved blade.

22.

Selection of needles can make a great differ ence in the ease and quality of the work, It is im portant that each needle be lust right for machine, thread and work being done.

Choose your needle carefully.

The correct size will permit thread to pass freely through needle eye; avoiding strain and breakage of thread.

Either right twist or left twist thread may be used.

NEEDLES AND THREAD

If trouble occurs during sewing:

Inspect needle point. A hook or burr may cause poor stitching or some materials may be cut when short stitches are used.

Check curvature of each needle, as instructed below. Unless needle has the correct curvature, it may cause skipping of stitches.

Orders for needles must specify the quantity required, the Size number and the

Catalogue number

For example

‘‘100 Size 9, Catalogue -#1265 (151 x

7) Needles.’’

The best stitching results will be obtained when using needles sold by Singer Sewing Machine

Company.

CURVATURE OF NEEDLE BLADE

(Gauge

164588 for Needles of Sizes

9 to

16 only)

Before making any stitching adjustments, the curvature of each needle blade should be checked in the following manner:

Using gauge 164588, shown in Fig. 6, insert shank of needle, with its flat side up, in the groove

A. Push the needle along the groove as for as it will go against stop B. Tighten clamping screw C.

Swing the indicator D, slowly to and fro, along the curve of the needle blade, observing the dis tance between the needle blade and the tip of the indicator.

The tip of the indicator should lust make con tact at the needle eye and should clear needle blade, at upper end of curve, by approximately

.005 to .006 inch. Use feeler gouge.

Reject any needle that cannot pass this test.

STITCH FORMATION

The four-thread dual chain stitch (Stitch

Type

#507) is shown in Fig. 9. An exceptionally strong overedge stitch and a single line of reinforced stitching run parallel and close to one another on the upper side of the material. The overedge is formed with thread from the right needle two looper threads. Threads carried by stitch and left looper and left needle form the reinforcing stitch which is interwoven with the overedge stitch underside of the fabric. See pages 9 and instructions on threading the machine on the

Fig. 14. Threading the Needles

Pass each thread through threading points, as shown in Figs. 11, 12, 14 and 16.

Use threading wire 164196, shown in Fig. 12, to pass threads through threading tubes, at points indicated in Figs. 11, 14 and 16. Draw four or more inches of thread through eyelet in threading wire and pass threading wire through required threading tube.

THREADING NEEDIE THREADS:

Before passing needle threads through thread ing tubes, turn machine pulley over away from operator until needles are at their lowest position.

The needle thread eyelet must be positioned and threaded as shown in Figs. ii and 14.

After threading needle thread eyelet, raise needles to highest position and pass each needle thread from front to rear through the eye of its respective needle. When threading each needle, double back the end of the thread and twist it; making thread stiff enough to thread the needle eye easily.

TO THREAD THE MACHINE (continued)

LOOPER THREADS:

Before threading left looper, turn machine pulley over from you until eye of left looper is directly in line with threading tube underneath throat plate.

When threading right looper (see Fig. 15) be sure that there is no loose ioop of thread on end of looper to cause thread breakage.

Pass each looper thread through its threading points, as shown in Figs. 12 and 16.

Draw about two inches of each needle thread through its needle eye and draw two inches of each looper thread through its looper eye, with which to start sewing.

REGULATION

THREAD TENSIONS

Tension on needle threads should be just sufficient to set stitch correctly.

(See Fig. 9, page 8 for correct stitch formation.)

For average sewing, tension on looper threads should be very light.

Regulate thread tensions as in structed in Fig. 17.

PRESSURE OF PRESSER FOOT

ON MATERIAL

Correct pressure of presser foot helps feed the work properly.

Always use lightest pressure pos sible.

Regulate the pressure of the presser foot on the material as instructed in

Fig. 17.

TO SHARPEN THE TRIMMER KNIVES ON


MACHINES 246K50

Knives on

Machine 246K51 should be returned to your SINGER Service Representative or to a

SINGER factory, when they require sharpening.

Knife Grinding Machine 701-9 (belt driven), is necessary for sharpening the knives used on Ma chine 246K50. The use of this grinder insures the correct bevel of the cutting edge of each knife.

If this Knife Grinder is not available, knives that require a new edge should be returned to your

SINGER Service Representative or to a SINGER factory for sharpening.

Do not attempt to sharpen these knives by hand.

Fig. 38. Sharpening the Movable

Knife

SHARPENING MOVABLE KNIFE D4:

Insert knife

D4, Fig. 38 in knife holder B5, Fig.

38 on front of lever arm

A5, Fig. 38.

Allow ap proximately

1/16 inch of the knife to extend be yond holder, for grinding. Then tighten thumb screw Z4, Fig. 38.

Turn thumb nut E5, Fig. 38 over from you until the knife D4 clears the grinding face

G5, Fig. 38.

While moving lever arm A5 alternately back and forth, turn thumb nut E5 as required, to bring the cutting edge of the knife lightly against the grind ing face of the wheel.

Continue the back and forth motion of the lever arm, grinding off only enough to sharpen the cutting edge.

The movable knife is thus ground to a shear ing edge, requiring no special setting in the ma chine to shear.
