Janome SUV 1108 Maintenance Sewing Machines Parts and Sales in Los Angeles

Anyone else have this machine? I've had mine about 3 years and want to give it a tune up. I thought I remembered seeing in the manual an image that indicated spots that required lubrication, but I've lost the manual and the one I found online doesn't mention lubrication at all. I also read that some of the newer machines don't require lubricant so maybe I just imagined the lubrication part? My machine is running fine at the moment and I'd like to keep it that way. Any tips appreciated!
