Fundamentals of Machine Operation • Whenever you have to turn the balance wheel, turn it toward you (counter-clockwise as shown by black arrow). Make sure the stop motion knob is tightened before you begin sewing. •

Never run a threaded machine unless you have fabric under the sew ing foot.

—-H’

• Place both threads back under the sewing foot before you put fabric into the machine. • The machine will feed the material under the sewing foot automatically. All you have to do is guide the work. • Always bring the take-up lever to its highest position before you begin and after you have completed a seam. Failure to observe this rule may cause the thread to slip out of the needle eye. Also, it is easier to remove the work with the take-up lever up.

DR 051

How to Operate Your Sewing Machine Engaging the Sewing Mechani sm .4 Hold balance wheel and turn stop motion knob clockwise (as indicated by black arrow). Disengaging the Sewing Mechani sm Hold balance wheel and turn stop motion knob counter-clock wise (toward you). The sewing mechanism is disengaged for bobbin winding.

The Workplate The workplate is used to enlar ge the working area for ordin ary sewing. Before you attach the workplate , raise the presser bar lifter and turn the balance wheel until the take-up lever is at its lowest position (see arrow at right). .4 Hold workplate level and push it between free arm and sewing foot. Tilt it slightly so that its lugs enter the holes in the mach ine base (see arrows in right illustration).

.4 Swing down the support and press it firmly against the base plate (see ill, at bottom).

Inserting a Full Bobbin into the Bobbin Case

R 5867

As shown in illustration 1, hold bobbin in left hand so that the thread end falls from the top down toward you, and insert bobbin into bobbin case.

Hold the bobbin firmly in the bobbin case and pull the thread into the case slot.

Pull the thread under the tension spring until it emerges from the opening at the end of the spring. Leave about three inches of thread hanging from the bobbin case.

Hold the case by its open latch so that the bobbin cannot Fall out.

iij Inserting the Bobbin Case Raise take-up lever to its highest point and lift the latch with the thumb and forefinger of your right hand. Turn bobbin case until slot points up (see arrow). Place bobbin case on center stud s of hook.

In replacing the bobbin case, it is best to hold the loose end of thread so that it will not get jammed between bobbin case and hook. Release the latch and press against bobbin case until you hear it snap into place. An improperly inserted bobbin case will cause needle breakage.

Recommended Needle and Thread Sizes

The appearance of the finished seam is de pendent on the correct relationship between needle, thread and fabric. Select the proper thread sizes and needles from this chart. The same size threads should be used in the needle and on the bobbin. Some experienced seamstresses prefer a somewhat thinner bob bin thread. However, the bobbin thread never should be thicker than the needle thread.

Regulating the Thread Tension The bobbin thread tension has been set for a medium grade at the factory and need not be adjusted for all ordinary sewing operations. If a special sewing operation should require a looser or tighter tension, turn the small knurled screw on the bobbin case as follows: for looser tension. W\ Turn it left for tighter tension.

The raceway in the sewing hook is the most important oiling point. Put one drop of oil into the raceway each day you sew.

From time to time, remove the needle plate and clean the machine feed with a soft brush Take a toothpick and remove accumulations of packed lint. Take out the bobbin case and the bobbin and clean the vicinity of the sewing hook.

Hemming Machine Setting: A = 0 or 2 to 3 (optional) B = The hemmer foot is indispensable if you want to sew a uniform hem. You can hem with straight or zigzag stitches, depending on the type of fabric you are using. Fold over edge of fabric about 1/8” to facilitate insertion into the hemmer foot. Place fabric under hemmer foot so that the needle stitches in the material about 1/2” short of its rear edge and close to the folded edge. Sew backwards as far as the rear fabric edge. Take the work out of the machine by pulling it forward. Don’t trim the threads (sketch 1). Draw the fabric into the scroll of the hemmer by pulling both threads back wards. Inserting the fabric into the scroll like this will ensure a neat hem right from the beginning. Feed fabric so that the hem edge is in line with the left edge of the hemmer scroll. Don’t crowd fabric into the scroll, but keep scroll well filled with fabric at all times (see ill, at top). DR 073

‘4 Avoid ugly ends by slowing down feeding. To do this, press the fabric against the needle plate on the left side of the foot before you come to the end of the hem (see ill, at bottoni). If you want to hem several edges, hem first edge to within about 1/2” of corner, cut away remaining portion of hem, as shown in sketch 2. Then hem the second edge, as instructed above. Before you hem the last edge, cut away about as illustrated in sketch 3.

Feed dog dropped. Script letters are best for monogram embroidery without a sewing foot. It requires a little practice. You will soon enjoy creative embroidery once you have learned to move the material at a uniform rate. The fabric should be held taut in the hoops and the presser bar lifter lowered. Let the needle stitch into the fabric at the beginning of your design and draw bobbin thread up through the fabric. Hold both thread ends and sew over outline, moving hoops slowly and evenly. To give your monogram dimensional quality, embroider outline twice. Be sure stitches are closely spaced.

Thread Size Pin tucks and narrow cording are made with a No. 50 embroidery thread, wider cording with sewing silk in the needle and on the bobbin. Set the machine for a medium stitch length (about 4). Upper Threading Place a spool of thread on each of the two spool pins. Pass both thread ends through both thread retainer openings 2, as Illustrated on page 15.

The bobbin thread is drawn up as instructed on page 16. To do this, hold both needle threads in your left hand.

Thread Tension Slightly increase the bobbin thread tension, and increase or decrease the needle thread tension depending on the type of fabric used. If the tension has been set correctly, the bobbin thread should appear as a faint zigzag line on the other side. Filled Cording If you want to make cording in filmy fabrics or render your cording more prominent, Pfaff recommends that you insert a filler cord, Its thickness depends on the cording size you want. Remove the bed slide and pass the filler cord through hole g from below (see ill, on page 41). Lay the end of the filler cord back under the cording foot (together with the needle and bobbin thread ends). Pull a filler cord forward under the bed slide and place the ball in your lap.
