"SAVE THESE INSTRUCTIONS"

"This sewing machine is intended for household use."

"IMPORTANTES INSTRUCCIONES DE SEGURIDAD"

If your sewing machine is fitted with a 3 pin non-rewireable BS plug then please read the following.

IMPORTANT (in the United Kingdom)

Main supply (AC 230/240V\~, 50Hz)

DO NOT cut off the mains plug from equipment. If the plug fitted is not suitable for the power point in your home or the cable is too short to reach a power point, then obtain an appropriate safety approved extension lead or consult your dealer.

BE SURE to replace the fuse only with an identical approved type, as originally fitted and to replace the fuse cover.

If none the less the mains plug is cut off ensure to remove the fuse and dispose of the plug immediately, to avoid a possible shock hazard by inadvertent connection to the main supply.

IMPORTANT (in the other countries)

If the available socket outlet is not suitable for the plug supplied with this equipment, it should be cut off and an appropriate three pin plug fitted. With alternative plugs an approved fuse must be fitted in the plug.

NOTE: The plug severed from the main leads must be destroyed as a plug with bared flexible cords is hazardous if engaged in a live socket outlet. In the event of replacing the plug fuse, use a fuse approved by ASTA to BS 1362, i.e. carrying the ASA mark, rating as marked on plug.

Always replace the fuse cover. Never use plugs with the fuse cover removed.

WARNING: DO NOT CONNECT EITHER WIRE TO THE EARTH TERMINAL WHICH IS MARKED WITH THE LETTER 'E', BY THE EARTH SYMBOL OR COLOURED GREEN OR YELLOW.

The wires in these main leads are coloured in accordance with the following code:

Blue Neutral

Brown Live

As the colours of the wiring in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:

The wire which is coloured blue must be connected to the terminal which is marked with the letter 'N' or coloured black or blue.

The wire which is coloured brown must be connected to the terminal which is marked with the letter 'L' or coloured red or brown.

Depending on your selected stitch, you may need to adjust the stitch length for best results.

The numbers marked on the Stitch Length Dial represent the length of the stitch in millimeters (mm). THE HIGHER THE NUMBER, THE LONGER THE STITCH.

The "O" setting does not feed the material. This is used for sewing on a button.

The “F” area is used for making a Satin Stitch (a dense zigzag stitch) which can be used in making buttonholes and decorative stitches. The position needed for making the Satin Stitch varies according to the material and thread being used. To determine the exact dial position, you should first test the stitch and length settings on a scrap of fabric to observe the feeding of the material.

Twin Needle Sewing

Your sewing machine is designed for twin needle sewing, which allows you to sew with two top threads. You can use the same color or two different colors of thread for making decorative stitches. Any of the patterns, except the buttonhole pattern, can be sewn with the twin needle. When using the Straight Stitch, the Stitch Width Dial should be set so that the needle is in the center position (between 2 and 3). However, when other patterns are used, set the Stitch Width Dial between 0 and 3. See page 15 for details on adjusting the Stitch Width Dial.

CAUTION:

When sewing with the twin needle, be sure the Stitch Width Dial is not set above 3 since this may cause the needle to hit the needle plate and break.

INSERTING THE TWIN NEEDLE

Insert in the same way a single needle is inserted (refer to page 9). The flat side of the needle should face toward the back and the rounded side should face toward you.

PLACING THE EXTRA SPOOL PIN

Place the vertical spool pin in the hole found on top of the machine near the horizontal spool pin. Place the second spool of thread onto the vertical spool pin as shown in fig. A.

TWIN NEEDLE THREADING

Each needle should be threaded separately.

  1. Threading the Right Needle Follow the same instructions for single needle threading using the thread from the spool on the extra spool pin. See page 26 for more details.

  2. Threading the Left Needle Thread the left needle in the same manner that the right needle was threaded, but do not pass the thread through the thread guide above the needle before passing it through the eye of the left needle as shown below in fig. B.

① Right needle thread passes through this guide.
② Left needle thread passes in front of this guide.

When the buttonhole is not sewn correctly: There are two different procedures for correcting buttonhole sewing, depending on which part of the buttonhole is not sewn correctly.

Correction Procedure 1 (See fig. A)

  1. Raise the Presser Foot Lever, then remove the fabric and all of the sewn thread.

  2. Pull the buttonhole lever slightly toward you.

  3. Sew about 10 stitches with no fabric in the machine.

  4. Place the fabric under the presser foot again, then lightly push the buttonhole lever toward the back of the machine and sew the buttonhole from the beginning.

Correction Procedure 2 (See fig. B)

  1. Raise the Presser Foot Lever, then remove the fabric and all of the sewn thread.

  2. Place the fabric under the presser foot again, then lightly push the buttonhole lever toward the back of the machine and sew the buttonhole from the beginning.

Ojales mal cosidos:

If the buttonhole lever is pushed toward the back of the machine while sewing any stitch other than a buttonhole, the buttonhole feed will be used and the stitch will not be sewn correctly.

If the buttonhole lever is accidentally pushed toward the back of the machine, lightly pull the buttonhole lever slightly toward you, sew about 10 stitches with no fabric in the machine, then raise the buttonhole lever.

Automatic Thread Cutting

(Model PS-2500, STAR140E)

NOTE:

Do not operate the Thread Cutter Lever while sewing or when there is no fabric in the sewing machine. Threads may become tangled or other problems may be incurred.

* When sewing with thread thicker than #30 or with nylon, metallic and other specialty threads, cut the threads with the thread cutter on the left side of the machine. Sewing without cutting the threads or with a needle thread that is too short may cause the threads to become tangled.
* Normally, the Thread Cutter Lever will move up and the sewing machine will stop operating after the threads are cut. However, the Thread Cutter Lever may stay down when certain threads and fabrics are used. If this occurs, slightly turning the balance wheel will allow the lever to move up. Starting to sew with the Thread Cutter Lever down will cause it to move up; and a problem may occur.
* Depending on the type of thread and fabric used, the needle may stay down near the needle plate after the threads are cut. This is not a malfunction. If this prevents the fabric from being removed from the machine, slightly turn the balance wheel away from you and raise the needle.
* Do not operate the Thread Cutter Lever when sewing with the twin needle. The threads may become tangled. During twin needle sewing, always cut the threads with the thread cutter on the left side of the machine.

If the Thread Cutter Lever stays down and the sewing machine cannot be used, raise the Thread Cutter Lever and check for the conditions mentioned on page 72. If the Thread Cutter Lever stays down, turn the balance wheel to raise the needle and raise the Thread Cutter Lever to its original position.

(Model PS-2500, STAR140E)

Correcting a Problem with the Automatic Thread Cutter

CAUTION:

Be sure to unplug the power supply cord in order to reduce the risk of injuries or electric shock.

  1. Turn off the main power supply.
  2. Raise the Presser Foot Lever and slightly turn the hand wheel either toward or away from you so that the tangled thread and the fabric can be removed.

①Hand wheel

  1. Turn the hand wheel toward you to raise the thread take-up to its highest position. If the bobbin holder has moved over the bobbin, move it to the left.

②Bobbin holder

  1. Remove the bobbin, then feed the lower thread again from the beginning.

(Modelo PS-2500, STAR140E)

text_image Diagram showing a hand operating a device with a knob and dial, labeled with number ①

Cyber Acoustics PS-2500 - CAUTION: - 1

text_image Technical diagram of a mechanical component with labeled parts and directional arrow indicating rotation or movement.

If the threads become tangled again or cannot be cut with the automatic thread cutter, even after performing the operation explained above, it may be possible that the threads are tangled under the needle plate. Clean the needle plate and shuttle as explained below.

  1. Turn off the main power supply.

  2. Raise the Presser Foot Lever and remove the fabric as explained in step 2 above. If the fabric cannot be removed, cut the thread on the back of the fabric with scissors and remove the fabric.

  3. Remove the presser foot holder, needle and needle plate as explained in "Cleaning" on page 65.

  4. Use tweezers to remove thread and dust from around the moving cutter.

* Sewing with thread and dust under the needle plate will prevent the moving cutter from operating properly and prevent the threads from being cut.

③Moving cutter

  1. Turn the hand wheel toward you and move the moving cutter and bobbin holder to the left again.

* Starting to sew with the moving cutter at the right will cause the threads to become tangled again. ④Bobbin holder
