NAME OF MAIN PARTS

FITTING THE SNAP·ON THE SEWING TABLE

Hold the snap-on sewing table on the slam as shown and set the concave recess to the convex projection of the machine pulling the stopper (I). (Figs. 1 & 2)b. Align the stopper (1) to the stopper hole (1) and release the finger to lock. Lower the snap-on sewing table down to a horizontal position pulling the stopper (2) toward the left. Align the stopper (2) to the stopper hole (2) and release the finger. (Figs. 1 & 3). When you change the bobbin. pull the stopper (2) only toward the left and push the left side: of the snap-on sewing table upward. You do not have to remove it completely.

TURNING THE LIGHT ON AND OFF

The sewing light is built into the face plate and is turned on and off using the push switch located on the right side of the vertical arm of the machine. When replacing the light bulb, first be sure to unplug your sewing machine. Swing out the face plate, then the light bulb is easily accessible and can be removed just as an ordinary light bulb (Fig. 1). Always ensure that the bulb is screwed in tightly.

CORRECT NEEDLE AND THREAD FOR FABRICS

INSERTING THE NEEDLE

It is very important to select the correct needle and thread to get a good stitch. Select the proper needle according to 10 the type or materials to be sewn, referring to the above chart. A bent needle will not produce good work. Check the needle by placing i1s nat side against a flat plane. If the needle is bcn1 or a sharp point has bcc:n damaged, a faulty needle: can cause

• thread breakage
• excessive: noise while the machine is in motion
• damage to the needle plate
• skipped stitching, etc. (Figs. 1 & 2)

Raise the needle bar to its highest point by turning the hand wheel toward you. Loosen the needle clamp screw and insert the needle upwards into the clamp as far as it will go, facing the flat side of the needle: lo the rear. Tighten the needle clamp screw with a screwdriver. (Fig. 3) After inserting the needle, check to see that it is correctly fitted. Turning the hand wheel toward you slowly, make sure that the needle is aligned with the center of the hole of the needle plate. During this procedure, the Uni dial must be set at “O”.

WINDING THE BOBBIN

To wind the bobbin, first, turn the stop motion large screw, counterclockwise to disconnect the sewing machines. (Fig. 1). Place a spool on the spool pin and guide thread as illustrated. (Fig. 2). Wind the thread around the bobbin several times and insert the bobbin on the bobbin winder spindle. (Fig. 3). Push the bobbin winder spindle in 1he direction of the arrow then turn the hand wheel slightly toward you while holding the end of the thread. (Fig. 3)

Place the foot control so that your fool rests on it comfortably. S1an the machine winding 1he bobbin
by gently pressing down 1hc foo1 con1rol. The more you press the fool control down, the faster the
machine runs. When the bobbin is full, the bobbin winder will be automatically released. Stop 1he machine and take it off after pushing the spindle back to its original position. Wind thread evenly as ”A” and avoid winding as “B” or hC”. After the bobbin has been wound, turn the stop motion a large screw clockwise to reconnect the sewing mechanism.

CHANGING THE PRESSER FOOT

To attach the shank, raise the needle bar 10 to its highest point by turning the hand wheel toward you anti attach the shank to the presser bar by means of the shank set screw. (Fig. 1) Place a presser foot exactly under the shank. Lower the presser bar by means of the presser bar lifter, checking to see that the groove of the shank fits the presser footpin. Then pull the one-touch lever. (Fig. 2). To take off the. presser fool, pull the one-touch lever after having raised the needle bar. (Fig. 3)

STRAIGHT STITCH SEWING

For normal straight-stitch sewing, set the machine as follows.

1. Uni dial …………………………………… 0
2. Feed dial ………………………………… I ~ 5
3. Drop feed …………………………….. .—-
4. Presser foot …………………………… Universal foot

For elastic straight stitch sewing, set the machine as follows. Please refer to SEWING ELASTIC MATERIAL on page 23.

1. Unidial ……………………………….. .—-
2. Feed dial ………………………………… J ~ S
3. Drop feed …………………………….. .—–
4. Presser foot ……………………….. Universal foot

In normal sewing. The universal foot is adequate. (Fig.2) In straight sewing, be sure that the needle is
aligned with the center of the needle hole of the presser foot and the needle plate by turning the hand wheel toward you. (Fig. 3)

START SEWING

Hold the upper thread lightly with your left hand. Turn the hand wheel toward you with your right hand until the needle enters into the needle hole catch the lower thread and come up again bringing it up through the needle hole. (Fig. 1) Pick up the ends of both threads together and draw them through under the presser foot to the back of the machine. ( Fig. 2)

Place the material under the presser foot and position the needle in the material. Lower the presser fool using the presser bar lifter and start sewing. (Fig. 3 & 4). It is not necessary to pull or push the fabric by
hand, just guilt it slightly in the desired direction. (Fig. 5) Place the foot control so that the foot rests on it comfortably. Start the machine by gently pressing down the foot control. The more you press the foot control button, the faster the machine runs.

CHANGING SEWING DIRECTION

To change the sewing direction, raise the presser foot leaving the needle in the material, and change the direction of the material. (Fig. 1)

After making the channel lower the presser foot and resume sewing. (Fig. 2) For reverse sewing push the reverse button. Reverse sewing will continue as long as the button is pushed. When the button is relesed the machine will return to forward sewing. (Figs. 1 & 2)

REMOVING MATERIAL

Stop the machine with the needle bar at the highest point. Raise the presser foot through the presser bar lifter and remove the material by pulling it diagonally to the left. (Fig. 1) Be sure to remove the material diagonally to the left and cut the thread with the thread culler. leaving about 12 cm (5″) frt:e at the ends. This makes it easier to resume sewing. (Fig. 2)

ADJUSTING ZIGZAG WIDTH
