I have never oiled or cleaned my machine. I know, it's such a bad idea! I probably need to get that done soon. Getting it done here by someone might be the death of it though. We have found that if something is working, getting work done on it, sometimes is the worst idea. My machine is happy, so maybe I'll just use the brush on it to get all that fuzz out of it that I can reach! I am not even sure what parts I would oil if I had some! Ha!
