Your manual should give you some instructions on removing lint and oiling your machine. Or go online and type in Cleaning a sewing machine and you will get tips on how to keep it running smoothly. After the first time, it will be easier to do it yourself, I understand sewing machine dealers often have a special so watch for that. It is a good thing to know how to take care of the machine yourself. Not as hard as it looks.
Look in your manual for tips.
