NEEDLE SIZE

Use KENMQRE needles. The size of the needle should conform to

the size of the thread and both should be suitable to the material. The same size thread should be used in the bobbin as on the

upper part of the machine for ordinary sewing. Never use a bent needle nor one with a blunt point.

This is the exact length of the needle to

be used in your machine. Comparison

with this illustration will determine whether the needle you have is the cor-

rect one for your machine.

PLACEMENT OF NEEDLE

Raise needle .bar to its highest position by turning hand wheel

toward you. Loosen needle clamp

screw. Hold the needle so that

the flat side is to your right. Slip

blunt end of needle as far as it

will go into needle clamp. Tighten

needle into place with needle clamp screw.

THREADING UPPER

MACHINE

PICKING UP BOBBIN THREAD

Raise presser foot lever. Hold needle thread loosely in left hand and rotate hand wheel toward you one complete turn.

Bring bobbin thread up by pulling upper thread. (See illustration).

Place threads back under presser foot.

ADJUSTING THE PRESSURE OF THE PRESSER FOOT

Push down latch of presser foot knob (See illustra- tion). This will release pressure of presser foot.

To increase pressure, push down round top of presser foot knob until suitable pressure is obtained.

When sewing multiple thickness or heavy material, you may prefer less pressure on the presser foot.

When sewing on sheer fabrics, more pressure may

be desired.

SETTING STITCH LENGTH

The stitch regulator controls the stitch length. Set lever to any

desired stitch length position between 0 and 4, and set by turn- ing knob clockwise until it stops. At No. 4 the longest stitch is

obtained. The size of stitch selected will depend on fabric you are sewing. To lengthen stitch, turn the knob counter clockwise

until the lever can be lowered to the position desired.

REVERSE STITCHING

Raise lever for reverse stitching. Lower lever for forward

stitching.

It is best to begin and end most seams with reverse stitching

often called back tacking.

FASTENING A SEAM

Lower needle into fabric. Lower presser foot and move lever up for reverse stitching. Turn hand wheel toward you and

stitch until needle reaches beginning of seam. Push lever down and complete seam. Fasten end of same. Cut thread

with cutter.

ADJUSTING TENSIONS

A perfect stitch will have threads locked between the two layers of fabric with no loops on top or bottom. (Refer to page 24)

Fig. 3

PROBLEM REMEDY

Upper thread too tight

Decrease Tension

:.[: :-

Upper thread too loose

o ......

Increase Tension

• =

When stitching Is unsatisfactory as in figures 2 and 3, adjust the upper thread tension. Lower thread tension requires adjustment less frequently than the

upper thread tension.

When stitch is satisfactory, as in figure

1 and seam is badly puckered, the

cause may be tight tensions and both

upper and lower may be adjusted. (See page 24)

INCREASE TENSION

Turn Clockwise.

DECREASE TENSION

When adjusting the tension on the

bobbin case, make slight adjustments

with a screwdriver. (See page 24)

Clockwise.

INSERTING AND REMOVING THE MATERIAL

For all kinds of sewing, consult chart on page 5.

Before placing the material on the machine,

see that:

• The presser foot and needle clamp screws are both tight.

• The sizes of needle and thread suit the kind of work to be done.

• The needle and take-up lever are at their highest position.

The ends of the threads have been drawn

about 4 inches to the rear of the machine.

• The feed dogs are up.

• Stitch length and width controls are set

at desired settings.

Experiment by sewing on the fabric to be used to determine tension adjustment and

correct stitch settings.

Place material under the presser foot, nsert

the needle into the material by turning the

hand wheel toward you, lower presser foot and start sewing.

To remove the work, first turn hand wheel toward you until needle is at its highest

position, then raise the presser foot, draw material to the rear and cut off excess

thread with the thread cutter located on the presser bar.

IMPORTANT: Always turn the hand wheel

toward you! When machine is not being

used, place a piece of material over the feed dog and lower the presser foot. Always have

fabric under the presser foot when operat-

ing the machine. Operating threaded ma- chine without fabric will cause it to jam by forcing thread into the shuttle." See page 20.

CHANGING THE PRESSER FEET

The various attachment feet available for certain

kinds of work are to be fastened to the presser bar.

To attach the foot, raise the presser bar to its highest

position by raising the presser foot lever. Loosen the presser foot thumb screw, choose the proper foot, insert from the front. Tighten the screw using

the large screw driver and make sure that the foot

is secure.

TURNING A CORNER

Stop sewing machine with needle in fabric. Raise

preseer foot. Turn fabric. Lower presser foot and continue stitching.

FEED DOG CONTROL

The drop feed control knob is situated on the right front of machine bedplate. When knob is turned to

the left, feed dog drops and does not pull material. This allows the operator freedom of movement of

material, as for darning. For regular sewing, turn knob to the right.
