That's the one I have! 4452. I was told "no oiling needed" by CS rep. They said nothing in the manual about cleaning, even. I did finally clean up the bobbin area, took out so much lint, it ran quieter. I'll have to look at that video.
Hop you are happy with your new machine, I love mine. First "non-vintage" machine I have had. I got it free from a dear friend.
