We get a lot of calls about sewing machine maintenance. In this video we will see how to maintain and clean the machine with the vertical hook, which is the most common construction in Redstar machines: Redstar R09S, R10S, R20S. It may happen that the machine stops sewing, tangles the threads, the stitch is ugly. Often the cause is prosaic, the thread has fallen into the looper somewhere and either blocks or makes work difficult. It is best to start by disassembling this part of the machine to remove the cause. It is very simple and we can see in this video. In addition, let's remember about regular maintenance of the machine, and it will repay you with long work. We carry it out with varying frequency depending on the intensity of work, even daily if necessary. It will take us literally 5 minutes. Once every six months, I encourage you to carry out a review on our website. The machine will be like new!
