Frequently Asked Questions - 57820 SINGER
How do I thread the Singer 57820 sewing machine?
Start by raising the presser foot and turning the handwheel to lift the needle to its highest position. Place the spool on the spool pin, draw the thread through the thread guide, then down between the tension discs. Continue through the take-up lever, then down to the needle area. Finally, pass the thread through the needle eye from front to back. Make sure to follow the numbered threading path indicated on the machine.
How do I wind a bobbin on the Singer 57820?
Place a bobbin on the bobbin winder spindle. Push the bobbin winder to the right until it clicks. Thread from the spool through the bobbin winding tension disc, then wind around bobbin a few times. Hold the end of the thread and press the foot controller gently to start winding. Once you have the desired length, stop and cut the thread, then push the bobbin winder left.
What type of bobbin does the Singer 57820 use?
It uses class 15 transparent bobbins, which are widely available. These bobbins are top-notch and allow you to see the thread level at a glance.
How do I adjust the stitch length and width?
Use the stitch length dial to set the desired length, typically between 0 and 4, where higher numbers create longer stitches. The stitch width dial adjusts the zigzag width and is used for decorative stitches. Refer to the stitch chart on the machine for recommended settings.
Why is my thread bunching underneath the fabric?
Thread bunching is usually caused by incorrect upper threading or a poorly inserted bobbin. Rethread the top thread, ensuring the presser foot is up when passing through the tension discs. Check that the bobbin is wound evenly and inserted in the correct direction. Also, verify that the bobbin case tension is balanced with the top tension.
How do I sew a buttonhole with the Singer 57820?
Attach the buttonhole foot provided. Select the buttonhole stitch on the stitch selector. Set the stitch length dial to the buttonhole setting (typically 'S' or between 0 and 1). Lower the needle and starting at the front mark, sew the forward side, then stop at the rear mark, press the reverse lever to sew the other side. The machine will create a four-step buttonhole automatically if you follow the steps labeled on the machine.
Can I sew heavy fabrics like denim or leather with this machine?
Yes, the Singer 57820 is capable of sewing medium-weight and some heavy-weight fabrics such as denim and canvas. Use a heavier needle (size 90/14 or 100/16) and adjust the tension and stitch length accordingly. For leather, use a leather needle and lower the presser foot pressure if possible, or use a walking foot for even feeding.
What maintenance does the Singer 57820 require?
Regularly remove the needle plate and clean out lint and dust with the small brush provided. Oil the machine lightly at the indicated points, using only sewing machine oil, after every 8-10 hours of use or as directed in the manual. Do not over-oil, and wipe up any excess. For long-term storage, keep it covered in a dry place.
How do I troubleshoot skipped stitches?
Skipped stitches are often caused by a dull, bent, or incorrect needle. Replace the needle with a new one, ensuring it is inserted fully and oriented correctly. Check that the needle is suitable for the fabric type (use a ballpoint for knits, sharp for woven). Also, verify that the threading path is correct and the machine is not under tension.
Are spare parts and accessories available for the Singer 57820?
Yes, Singer offers a wide range of spare parts and accessories for this model, including bobbins, needles, feet, and belts. You can find them at authorized Singer dealers or online through official parts distributors. The machine has a 25-year limited warranty, so ensure any repairs are done by qualified service centers to maintain coverage.
