JoeJr gives good advice. . Turn the machine over and oil all the oil holes and every place there is metal to metal movement. Also since you have a machine with cams, they are more likely than straight stitchers to get gummed up with old oil. heat from a hair dryer can loosen up the old oil and let your new oils soak in. BE Patient. I have been using heat and penetrating oil ( that I rarely use) on a Husqvarna -Viking. After 3 weeks the zigzag lever is turning free enough I can do it cold. Until today It would not turn when it cooled down. Not ready to go back to the owner though. I have pretty strong hands. More heat and oil to come...
