According to this machines manual, you also take the bottom cover off and oil there in 5 places. After opening the face cover plate it is showing 7 places there, also at the base of where you set the bobbin to wind it, and the usual places from the top of the machine. If I can get the scanner hooked up tonight I will see if it will scan, as the diagrams are a real funky green color, (gotta love the 70's avocado green).
