Be careful where and what you buy the grease/lubricant. Friday I took a 7 hour class on how to take apart, clean with kerosene, oil and lubricate my Featherweight machine. The instructor was Nova Montgomery. If you go to her website you can purchase what you need. She and a chemist produced and patent her lubricant. It goes only on the two sets of gears and in the motor. Oil goes on the bushings and designated sites. Sorry for such a long post but we all learned so much.
