If you do a lot of sewing
Lint, thread and broken needles can collect in the needle bar, hook and feed mechanisms, causing problems ranging from noise to more serious problems that can stop the machine from functioning. Heavy use can also remove oil on moving parts that the machine needs to operate smoothly. Lint and thread build up can cause serious tension problems.
If you sew occasionally:
Lint, thread and broken needles can still collect in the needle bar area and in the gears of the thread-handling mechanism. Even moderate use necessitates oiling of moving parts of the sewing machine. A small piece of thread in the tension unit will necessitate cleaning and recalibration of the tension.
If your sewing machine has been in the closet for a few years and you want to sew again:
The machine should be tuned up so that you will have peak performance of the machine and trouble free sewing. Even sitting in the closet, the oil in the machine can and will dry out which will lock up parts and potentially lead to further damage of the machine.
Thorough servicing by the Sewing Studio Fabric Superstore will eliminate all of these problems and guarantee trouble free sewing.
