I have 2 Janome machines and the manuals don't say a word about oiling the machine. My dealer told me to add a drop of oil on the wick in the center of the bobbin housing every time I clean the bobbin area. With my first machine I thought the wick was just lint and removed it--took a lot of work and not recommended--I managed to put it back in and never had a problem. Oh, to be young and dumb again!!! lol
