Frequently Asked Questions - HD6620C SINGER

How to thread the machine correctly?

Raise the presser foot and place the needle in the highest position. Follow the thread path: thread guide, tension discs, take-up lever, lower thread guide, then thread the needle from front to back. Use the built-in needle threader if desired.

What to do if the thread tangles under the fabric?

This usually indicates incorrect upper threading. Rethread the machine making sure the thread passes correctly through the tension mechanism and the take-up lever. Also check that the bobbin is inserted correctly.

How to adjust the thread tension?

Turn the thread tension dial on top of the machine. For balanced stitching, the threads should meet in the middle of the fabric. If the bobbin thread appears on top, reduce the tension; if the upper thread appears underneath, increase it.

How to change the needle?

Turn off the machine. Loosen the needle screw, remove the old needle, insert the new one with the flat side toward the back, then tighten the screw. Use the provided L-screwdriver if necessary.

What to do if the machine does not advance the fabric?

Check that the presser foot is lowered, the feed dogs are raised (operate the lever at the back of the free arm), and the stitch length is not set to zero.

How to make a buttonhole?

Use the one-step buttonhole foot. Insert the button into the button holder at the back of the foot to set the length. Place the fabric under the foot, lower the buttonhole lever, then press the pedal. The machine automatically sews the buttonhole.

How to clean the bobbin area?

Turn off the machine. Remove the presser foot, bobbin cover, bobbin, and then the needle plate. Use the provided brush to clean the feed dogs and the compartment. Reassemble in reverse order.

What to do in case of upper thread breakage?

Check that the thread is not caught on the spool or behind the spool pin, that the machine is correctly threaded (raise the presser foot and rethread), and that the thread tension is not too high. Reduce the tension if necessary.

How to wind the bobbin?

Place the thread on the spool pin and guide it around the winding tension disc. Insert the thread through the hole in the bobbin, place the bobbin on the winding shaft, then push the shaft to the right. Hold the thread end and press the pedal. The machine stops automatically when the bobbin is full.

What to do if the machine does not start?

Check that the bobbin winding shaft is not engaged (push it to the left), that the power cord and foot pedal are properly plugged in, and that the switch is set to 'I'. If the problem persists, contact an authorized service center.

Unpacking the Machine

1. Place the box on a steady, flat surface. Lift the machine out of the box, and remove the packaging.
2. Remove all outer packing material and the plastic bag.
3. Wipe off the machine with a dry cloth to remove any lint and/or excess oil around the needle area.

Note: Your sewing machine is adjusted to provide the best stitch result at normal room temperature. Extreme hot and temperatures can affect the sewn result.

Connect to the Power Supply

Among the accessories you will find the power cord and the foot control.

Note: Consult a qualified electrician if in doubt as how to connect the machine to the power source. Unplug the power cord when the machine is not in use.

For this sewing machine, foot control model C-8000 manufactured by Zeng Hsing, Taiwan must be used.

On the bottom right side of the sewing machine, you find the connecting sockets and the ON/OFF button.

1. Connect the foot control cord to the front socket on the bottom right side of the machine (A).
2. Connect the power cord to the rear socket on the right side of the machine (B). Plug the cord into the socket.
3. Press the ON/OFF switch (C) to "I" to turn on pow light.

The sewing speed is regulated by pressing the foot control.

For the USA and Canada

This sewing machine has a polarized plug (one blade wider than the other). To reduce the risk of electric shock, this pl is intended to fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it does not fit, contact a qualified electrician to install the proper outlet. Do not modify the plug in any way.

Note: After turning off the machine, residual power may remain in the machine. This could cause the light to stay on for a few seconds while the power is consumed. This is normal for an energy efficient appliance.

Packing Machine after Sewing

1. Switch the main switch off. After switching off, residual power may still remain in the machine. This may cause the light to stay on for a few seconds while the power is consumed. This is normal behavior for an energy efficient appliance
2. Unplug the cord from the wall socket and then from the machine.
3. Wind the cord around the foot control for easy storage.
4. Place all accessories in the accessory tray. Slide the tray on to the machine around the free arm.
5. Place the foot control and cord in the space above the free arm.
6. Place the soft cover on the machine to help protect it from dust and lint.

Free Arm/Removable Accessory Tray

Store presser feet, bobbins, needles and other accessories in the accessory tray so that they are easily accessible.

Keep the accessory tray on the machine to provide a large flat work surface.

Use the free arm to facilitate sewing trouser legs and sleeve hems. To use the free arm, slide off the accessory tray. When attached, a hook keeps the accessory tray securely attached to the machine. Remove the tray by sliding it to the left.

When the accessory tray is removed from the machine, open the door by putting a finger in the groove at the left side of the accessory box (A) and carefully pull it open. Push the door closed before putting the tray back onto the machine.

Presser Foot Lifter

The presser foot lever is located at the right side of the sewing machine head. The lever is used to raise and lower the presser foot. Raise the lever up for machine threading, lower it for sewing.

By raising the presser foot lever and then pressing it farther upwards, the lift height of the presser foot is increased to an extra height allowing you to slide very thick projects under the foot.

Thread Knife

To use the thread knife, pull the thread from back to front as illustrated. Doing this will leave the thread ends long enough so that the needle doesn't become unthreaded when you start to sew again.

Mechanical assembly diagram showing a pump, valve, and wiring (no text or labels)

Spool Pin

Your machine has two spool pins, a main spool pin and an Auxiliary Spool Pin. The spool pins are designed for all types of thread. The main spool pin is used in a horizontal position (the thread reels off the spool) and the Auxiliary Spool Pin in a vertical position (the thread spool rotates). Use the horizontal position for normal threads and the vertical position for large spools or specialty threads.

Main Spool Pin

Place the thread spool on the spool pin. Make sure that the thread reels off the spool counter clockwise and slide on a spool cap. Use a spool cap slightly larger than the thread spool. For narrow thread spools (A), use a smaller spool cap in front of the spool. For large thread spools (B), use a larger spool cap in front of the spool. The flat side of the spool cap should be pressed firmly against the spool. There should be no space between the spool cap and the thread spool.

Note: Not all thread spools are manufactured in the same If you experience problems with the thread, turn it in the opposite way or use the vertical position.

Auxiliary Spool Pin

The Auxiliary Spool Pin is used when winding a bobbin thread from a second spool of thread or when sewing with large spools or with specialty threads. Insert the Auxiliary Spool Pin into the designated hole at the top of the machine. Place a felt pad under the thread spool. This is to prevent the thread from reeling off too fast. Do not place a spool cap on top of the spool pin as that would prevent the spool from rotating.

Needle Threader

The built-in needle threader allows you to thread the needle quickly and easily.

The needle must be in its highest position to use the built-in needle threader. Turn the hand wheel towards you until the needle is in its highest position, or press the needle up/down button. It is also recommended that you lower the presser foot.

• Use the handle (A) to pull the needle threader all the way down. The metal flanges cover the needle. A small hook will pass through the needle eye (B).
• Place the thread from the back over the thread guide (C) and under the small hook (D).
• Let the needle threader gently swing back. The hook pulls the thread through the needle eye and forms a loop behind the needle. Pull the thread loop out behind the needle.
• Raise the presser foot and place the thread under it.
• Pull out about 6–8" (15–20cm) of thread beyond the needle eye. This will prevent the machine from coming unthreaded when you start to sew.

Note: The needle threader is designed to be used for size 70-110 needles. You cannot use the needle threader for size 60 needles or smaller, wing needles or twin needles. There are also some optional accessories that require manual threading of the needle. When threading the needle manually, make sure that the needle is threaded from front to back.

Needles

The sewing machine needle plays an important role in successful sewing. Use only quality needles. We recommend needles of system 130/705H. The needle package included with your machine contains needles of the most frequently used sizes

Be sure to match the needle to the thread you are using. Heavier threads require a needle with a larger needle eye. If the needle eye is too small for the thread the needle threader may not work properly.

Universal Needle

Universal needles have a slightly rounded point and come in a variety of sizes. For general variety of fabric types and weights.

Stretch Needle

Stretch needles have a ball point and a special scarf to eliminate skipped stitches when there in the fabric. For knits, swimwear, fleece, synthetic suedes and leathers.

Denim Needle

Denim needles have a sharp point to penetrate tightly woven fabrics without deflecting the n-canvas, denim, microfibers.

Embroidery Needle

Embroidery needles have a special scarf, a slightly rounded point and a slightly larger eye t damage to thread and materials. Use with metallic and other specialty threads for embroidery decorative sewing.

Wing Needle

Wing needles have wide extensions on each side of the needle to poke holes in the fabric entredeux and other hemstitches on natural fiber fabrics.

Important Needle Information

Change the needle often. As a general rule, needles should be changed every 6-8 hours of actual stitching time.

Always use a straight needle with a sharp point and make sure the point is not bent or damaged (A).

A damaged needle (B) can cause skipped stitches, breakage or snapping of the thread. It can also damage the needle plate.

Do not use asymmetrical twin needles (C), they can damage your sewing machine.

Thread Tension

To set the thread tension, turn the dial on top of the machine. Depending on the fabric, thread, etc., the tension may need to be adjusted. For the best stitch appearance and durability, make sure the needle thread tension is correctly adjusted. For general sewing, the threads evenly meet between the two layers of fabric (A).

If the bobbin thread is visible on the top side of the fabric, the needle thread tension is too tight (B). Reduce the needle thread tension.

If top thread is visible on the underside of the fabric, the needle thread tension is too loose (C). Increase the needle thread tension.

Diagram of a corrugated structure with no text or symbols

For decorative stitches and buttonholes, the top thread should be visible on the underside of the fabric.

Make a few tests on a scrap piece of the fabric you are going to sew and check the tension.

Sew without Feed Teeth

When sewing on buttons or doing other sewing techniques where you don't want the fabric to feed, you need to lower the feed teeth.

The feed teeth lever is found at the back of the free arm.

1. Lower the feed teeth by moving the lever to the "Feed Teeth Down" position.

2. Raise the feed teeth by moving the lever to the "Feed Teeth Up" position.

Note: The feed teeth will not raise immediately when the lever is switched. Turn the hand wheel toward you one full turn or start sewing to re-engage the feed teeth.

Presser Foot Pressure

The presser foot pressure is used to control the amount of pressure that the presser foot exerts onto the fabric, to ensure smooth feeding of the fabric while sewing. The presser foot pressure has been pre-set to the standard value "2". Though it needs no adjustment for most fabrics, it can be adjusted for very thick or very thin fabric - increase for heavy weight fabrics, decrease for lightweight fabrics.

Note: If the dial is turned counterclockwise too much, it could come off. If this happens, simply replace the dial and turn it clockwise until it stays in place.

Note: If the dial is turned clockwise until it comes to a stop, it has reached the maximum pressure available. Do not try to turn the dial any further!

Change the Presser Foot

1. Make sure that the needle is in the highest position and the presser foot is lifted. The presser foot release lever extends out the back of the presser foot holder. Press this lever to release the presser foot.

2. To attach a presser foot to the holder, place the desired presser foot with its pin directly under the slot in the presser foot holder. Lower the presser foot lifter and the presser foot will snap into place.

Note: If you find it difficult to place the presser foot in correct position, keep the release lever pressed while lowering the presser foot. Use your thumb to carefully guide the presser foot into the correct position and it will snap into place.

SEWING

Sewing

Next to each stitch or sewing technique described in this section of the manual is a chart showing the recommended settings and presser foot. See sample of the chart to the right.

Note: Some fabrics have a lot of excess dye which can cause discoloration on other fabric but also on your sewing machine. This discoloring may be very difficult or impossible to remove. Fleece and denim fabric in especially red and blue often contain a lot of excess dye. If you suspect that your fabric Stitch ready-to-wear garment contains a lot of excess dye, always Presser foot pre-wash it before sewing to avoid the discoloring on your C.

D. Stitch length in mm

Note: For best sewing result, use the same thread on top. thread tension bobbin. If sewing with specialty/decorative threads, use regular sewing thread in the bobbin.

Start to Sew - Straight Stitch

Set your machine for straight stitch (see chart to the right).

Raise the presser foot and position the fabric under it, seam allowance guide line on the needle plate. On the cover there is a 1/4" (6mm) guide line.

Place the top thread underneath the presser foot.

Lower the needle to the point where you want to start. Bring the threads toward the back and lower the presser foot. Pass the foot control. Gently guide the fabric along the scam guide letting the machine feed the fabric (A). If the bobbin thread isn't pulled up, it will be automatically as you start to sew.

To secure the beginning of a seam, press and hold the reverse button. Sew a few reverse stitches. Release the reverse button and the machine will sew forward again (B).

MAINTENANCE

Cleaning the Machine

To keep your sewing machine operating well, clean it often. No lubrication (oiling) is needed. Wipe the exterior surface of your machine with a soft cloth to remove any dust or lint built up.

Cleaning the Bobbin Area

Raise the needle and turn off the machine.

Remove the presser foot. Slide off the bobbin cover and remove the bobbin.

Remove the screws in the needle plate by using the L-screwdriver. Lift up and remove the needle plate.

Clean the feed teeth and the bobbin area with the brush found among the accessories.

Place the needle plate over the feed teeth, replace and tighten the screws.

Attach the presser foot, insert the bobbin and replace the bobbin cover.

Cleaning under the Bobbin Area

Raise the needle and turn off the machine.

Clean the area under the bobbin case after sewing several projects or any time you notice an accumulation of lint in the bobbin case area.

Remove the presser foot. Slide off the bobbin cover and remove the bobbin.

Remove the screws in the needle plate by using the L-screwdriver. Lift up and remove the needle plate.

Remove the bobbin case by lifting it up. This is easier if you push it slightly to the left or right as you lift.

Clean the area with the brush or with a dry cloth.

Note: Do not blow air into the bobbin case area. The dust and lint will be blown into your machine.

Guide the "forked" end of the bobbin case (A) under the bobbin case holder (B) and under the feed teeth. Move the bobbin case slightly from right to left until it slips correctly into the hook race (C). To make sure the bobbin case is properly replaced, turn the handwheel towards you. The hook race (C) should rotate freely in a counter-clockwise direction.

Troubleshooting

Thread Loops on Underside of Fabric

Possible cause: Thread looping on the underside of the fabric is always an indication that the upper thread is not threaded. This happens when the upper thread is not correctly placed in the thread tension mechani has not been threaded through the take up lever.

Solution: Rethread the machine, making sure to first raise the presser foot lifter before starting to thread, so can be properly seated in the tension mechanism and take up lever. To know if you have rethread machine correctly, try this test:

• Raise the presser foot lifter (page 9) and thread the top of the machine (page 12).
• Thread the needle, but don't put the thread under the presser foot yet. As you pull the upper thread to the left, it should pull freely.
• Put the presser foot lifter down. As you pull the upper thread to the left, you should feel resistance. This means you are threaded correctly.
• Put the thread under the presser foot, and then draw up the bobbin thread. Slip both thread tails under the presser foot towards the back. Lower the presser foot and begin sewing.

If you put the presser foot lifter down, but the thread still pulls freely (you feel no difference with presser foot is up or down), this means that you have threaded incorrectly. Remove the upper three rethread the machine.

Bobbin Thread Breaking

Possible cause: Bobbin threaded incorrectly.

Solution: Check that bobbin is placed correctly in the bobbin holder (page 11).

Possible cause: Bobbin wound too full or unevenly.

Solution: Bobbin thread may not have been correctly placed into bobbin winding tension disc during the bot winding process (page 11).

Possible cause: Dirt or lint in bobbin holder.

Solution: Clean bobbin holder (page 27).

Possible cause: Wrong bobbins being used.

Solution: Use bobbins that are the same style as those that come with the machine (SINGER® Class 15 tr. bobbins) - don't substitute.

Bobbin Thread Showing on Top of Fabric

Possible cause: Top thread too tight.

Solution: Reduce upper thread tension (page 15).

Possible cause: Thread path is obstructed, putting extra tension on top thread.

Solution: Check that the top thread path is not obstructed and thread is moving freely through the thread.

Possible cause: Bobbin thread not in bobbin case tension.

Solution: Rethread bobbin (page 11).

Bobbin Winding Difficulties

Possible cause: Bobbin thread loosely wound on bobbin.

Solution: Rewind bobbin, making sure that the thread is placed snuggly in the bobbin winding tension disc 11).

Possible cause: Bobbin winding spindle not fully engaged, therefore bobbin not winding.

Solution: Check that the bobbin winding spindle has been fully engaged before starting to wind.

Possible cause: Bobbin is winding sloppily because thread end not held at beginning of winding process.

Solution: Before starting to wind, hold the thread tail (coming out of the bobbin) securely, allow the bobbin partially fill, then stop to trim the thread tail close to the bobbin.

Fabric Puckers

Possible cause: Top thread is too tight.

Solution: Reduce top thread tension (page 15).

Possible cause: Stitch length is set too short.

Solution: Increase stitch length setting (page 17).

Possible cause: Wrong style needle for fabric type.

Solution: Use correct needle style and size for your fabric (page 13 and page 14).

Fabric Is Tunneling Under Stitches

Possible cause: Fabric is not properly stabilized for the density of the stitches (for example, satin stitch appliqu

Solution: Add a fabric stabilizer underneath the fabric to help keep the stitches from tunneling in together a puckered ridge in fabric.

Loud Noise When Sewing

Possible cause: Thread not in take-up lever.

Solution: Rethread the machine, making sure the take up lever is in its highest position so thread goes the take up lever — turn machine hand wheel toward you to raise the take up lever to its key for threading.

Possible cause: Thread path is obstructed.

Solution: Check that thread is not caught on the thread spool or behind the spool cap.

Machine is Not Feeding Fabric

Possible cause: Presser foot lifter has not been lowered onto fabric after threading.

Solution: Lower the presser foot lifter before starting to sew. Don't "push" or "pull" the fabric as you

Possible cause:

Solution: The feed teeth need to be raised and re-engaged by turning the handwheel one full revolution

Possible cause: Stitch length is set at zero.

Solution: Increase stitch length setting (page 17).

Machine Will Not Run

Possible cause: Bobbin winding spindle is engaged when you try to sew.

Solution: Disengage bobbin winding spindle by pushing it to the left.

Possible cause: Power cord and/or foot control not plugged in correctly.

Solution: Make sure power cord/foot control are correctly seated in machine and power supply (page 8).

Possible cause: Wrong bobbins being used.

Solution: Use bobbins that are the same style as those that come with the machine (SINGER® Class 15 bobbins)—don't substitute.

Needles Breaking

Possible cause: Bent, dull or damaged needle.

Solution: Discard needle, insert new needle (page 14).

Possible cause: Wrong size needle for fabric.

Solution: Insert appropriate needle for fabric type (page 13).

Possible cause: Machine not threaded correctly.

Solution: Rethread the machine completely (page 12).

Skipping Stitches

Possible cause: Needle inserted incorrectly.

Solution: Check that flat side of needle top is toward back of machine and needle is up as far as it can tighten needle clamp screw.

Possible cause: Wrong needle for fabric sewn.

Solution: Use correct needle style and size for your fabric (page 13 and page 14).

Possible cause: Bent, dull or damaged needle.

Solution: Discard needle and insert new needle (page 14).

Stitches Distorted

Possible cause: “Pushing” or “pulling” the fabric.

Solution: Don't manually push/pull fabric in order to sew, but allow the machine's feed teeth to draw fabric presser foot as you guide it.

Possible cause: Incorrect stitch length setting.

Solution: Adjust stitch length setting (page 17).

Possible cause: Stabilizer may be needed for technique.

Solution: Place stabilizer underneath fabric.

Thread Bunching at Beginning

Possible cause: Top and bobbin threads have not been properly placed underneath presser foot before starting to se

Solution: Ensure that both the top thread and the bobbin thread are under the presser foot and toward the before starting to sew.

Possible cause: Sewing was started with no fabric under the presser foot.

Solution: Place fabric under foot, making sure that needle comes down into fabric; lightly hold both three first few stitches.

Possible cause: Stabilizer may be needed for technique.

Solution: Place stabilizer underneath fabric.

Upper Thread Breaking

Possible cause: Thread path obstructed

Solution: Check if thread is caught on thread spool (rough spots on the spool itself) or behind spool pin cap (if the thread has fallen behind the spool cap and therefore cannot feed freely through the path).

Possible cause: Machine is not threaded correctly.

Solution: Remove upper thread completely, raise presser foot lifter, rethread machine making sure thread i. up lever (raise take up lever to its highest position by turning hand wheel toward you.

Possible cause: Upper tension too tight.
