The most important part of doing maintenance is to do proper cleaning of the machine parts like bobbin raceway, feed teeth, needle plate, etc. It must be remembered that the machine should be cleaned properly before oiling as it can lead to accumulation of fluff and dust around the oil thus jamming the machine. It is always advisable to use good quality thread as it produces fewer amounts of fluff.
The care and maintenance of a sewing machine help to improve its working. This consists mainly of cleaning, oiling, and right handling, which contributes to good output, quality production, and safety of the workers. Care and maintenance are also necessary in order to operate the machine smoothly and for its long term use. It is very important to identify the sewing defects such as upper thread break, bobbin (lower) thread break, bunching of threads, skipped stitches, irregular stitches and stitches that are not formed properly, etc., for the proper working of the sewing machine and good quality production. This Unit discusses the cause and different defects and the corrective action to be taken.
