Don't panic! First, ask yourself these four questions. Make this a rule for yourself: new sewing project, new needle. Sewing machine needles can become dull after about 7 hours of sewing, and a needle that's dull, bent, or simply old can easily make your stitches skip. At the same time, make sure that your needle is in all the way, if you don't loosen the screw all the way before you insert, then your needle may by to low.
Not only can this make stitches skip, it can actually damage your sewing machine. Most times when your machine is acting up, a simple re-thread of your sewing machine is the answer!
Make sure that the thread is in the tension disk and the spool is placed correctly on the machine. Also, double-check to see if the bobbin is in the correct way and threaded tightly. Sometimes, a poorly wound bobbin is the culprit for skipped stitches. As with any piece of mechanical equipment, the life of a serger and the quality of its performance are greatly enhanced by regular care, maintenance and some basic troubleshooting knowledge.
The good news is that sergers are relatively simple to care for. It only takes a few minutes to keep them running well. Clean the serger on a regular basis.
Some fabrics create a great deal of lint and fuzz; these require more frequent serger cleanings. Others are relatively lint-free, meaning the serger can go longer between cleanings. Gather a few tools to help the process go quickly and smoothly. For deep cleaning, unthread the machine and remove the presser foot and needles.
Some models may also allow the removal of the throat plate. Open both doors of the serger for full access to the loopers. Using a soft brush, such as a paintbrush, lint brush or make-up brush, clean the lower area of the serger. Remove all lint from the loopers and the feed dog area. A brush that has stiff bristles is also useful in certain areas to push lint out of the machine.
Pull long threads from the machine using tweezers if needed. Use a pipe cleaner for hard-to-reach areas. The stiffness of the cleaner paired with its flexibility allows it to snake into areas too small for hands. The texture of the pipe cleaner acts as a dust catcher to remove lint. Use a small vacuum or vacuum attachment to remove lint quickly. This can potentially build up inside the serger, causing difficulty for the moving parts.
After cleaning the looper area, oil the needed areas using the type of oil recommended by the serger manufacturer. Another cause may be that the needle and thread are mismatched. Why is my zig zag stitch not working? Try some of the simple things first. Remove the bobbin plate using a screwdriver and then remove the bobbin. Clean out any lint that may be under the bobbin and which may cause your zigzag stitch not to work. Replace the bobbin and the bobbin plate and test your zigzag stitch.
How do you adjust the tension on a sewing machine? Adjust your top tension if it's too loose. To increase your top tension if it's too loose, turn your knob so that the numbers are increasing. Continue until it looks even on both sides and you can no longer see the bottom thread on the top. Why is my thread shredding?
The most common reason why thread shreds, frays, or breaks at the needle is because the eye is too small to accommodate the thread, causing stress and friction, which results in shredding or breaking the top thread.
How a stitch is formed? Stitch Forming Devices During sewing the needle descends through the fabric to the bottom of its stroke and as the needle rises a loop of sewing thread is formed in the scarf of the needle. The sewing machine hook be it rotary or oscillating shuttle interlocks the needle thread with the bobbin thread. Why does my sewing machine keep jamming? Fabric jamming in your machine may be caused by the feed dogs. The feed dogs are those tiny teeth along the sewing machine underneath the presser foot as those teeth pull the fabric through when the needle is making stitches.
Lint or debris in the feed dog area can jam the mechanisms preventing them to move.
