Things You'll Need
Instructions
Unplug your sewing machine and place it in a well-lit area. Keep a flashlight handy for peering into the sewing machine.
Take the needle, presser foot, bobbin case and slide plate off of the sewing machine. As you remove pieces, note their position so you can replace them correctly. Use a small screwdriver with a blade that fits the size of screw you encounter.
Take any lint and thread ends out of the bobbin area. Use tweezers too pick up small pieces of debris that are stuck or wound around the bobbin working parts.
Brush the bobbin casing and under the needle plate, with a narrow soft nylon brush or blow it away with a can of pressurized air.
Clean out oil holes with a sharp needle or other pointed tool.
Turn the sewing machine handwheel by hand, as you squirt fine sewing machine oil into oil holes and any places where parts rub against each other.
Wipe excess oil off of the sewing machine with a soft cloth. Replace all pieces back in their original locations.
