I just want to give a warning. It doesn't give any directions in the manual for oiling. My machine froze up yesterday. I did a good cleaning. Nothing. I decided to oil what I could see and worked the wheel until it loosened up. I let it sit until I got home from work today. Put it back together and it is working like a new machine. I told my DH the other day that it sounded like it needed oiled and was going to take it in. The moral is if it sounds like it needs oil....it does!
