Nowhere in the manual did it tell me to oil this spot and my dealer didn't tell me in spite of numerous complaints from me about the loud bobbin that would jump out of the case and jam. This problem even caused my needle to puncture a hole in the bobbin case and then my dealer charged me $25 to replace it and called it operator error. I finally found out about this crucial oiling spot from another owner on the Janome 6500 Yahoo group. Other Janome machines may also need oiling here as well. I know my friend was having the same problem with the rattling jumping bobbin with her Janome Jem and the oil drop fixed her machine too. I guess over time that little bit of wick just dries out.
