Common faults of computer flat car at work

The computer flat car often encounters various problems during the working process, which makes the machine unable to work normally. Here are some problems and solutions I listed for you:

Sudden stop during sewing: It may be that the sewing machine has been in operation for a long time, and the motor power is automatically turned off due to overheating of the machine. At this time, it takes about half an hour for the machine to start working again.

The machine does not feed: This happens if the stitch length is set to 0. Check the position of the feed dog again. If the position of the feed dog is too low, the feeding cannot be completed.

It is necessary to reset the stitch length and raise the feed dog.

Broken needle: There are many cases of broken needles, such as sewing thick materials with thin needles, improper installation of machine needles, improper selection of presser feet, loose presser feet, etc. may cause needle breakage. If the machine needle is not suitable, it needs to be replaced with a suitable machine needle, and if the installation is not in place, reinstall it. If it is a problem with the presser foot, replace the presser foot or reinstall the presser foot.

Bottom thread breakage: In general, this situation may be that the bobbin is not installed properly, or the bobbin is caught by the thread. At this time, we must carefully check the installation of the bobbin to ensure that it is installed in a proper position. If the bobbin is found If you are entangled by the thread, you have to untangle the thread, and that's it.
