How to solve the thread jam and broken needle of sewing machine?

There will always be large and small problems in the process of using the sewing machine. When encountering problems, we must patiently find out where the problems occur, and then go to solve the problems slowly. Always pay attention to the maintenance of the machine and lubricate the machine. If you want the service life of the machine to be longer, the maintenance of the machine cannot be ignored.

First of all, look at the service life of the machine, whether the machine is aging, and the parts are seriously worn out for a long time. Second, check the traces left after the needle is broken, and see if you can find out the cause of the broken needle through the traces. These problems may also be caused if the operator is not skilled enough.

Then check if there is any problem with the spare parts of the machine. Loose presser foot screws, skewed presser feet, and misalignment of the machine needle with the presser foot groove may also cause the above problems, which should be adjusted in time. Then check whether the needle is installed properly. If the needle is not installed, the needle is installed backwards, or the needle is too long or too short. The needle is too long and it is easy to break, and the needle is too short and it will jump. Thread, generally like this situation can only replace the needle or reinstall the needle.
