2, Apply one drop of oil to the section shaded in the figure below( section protruded from the nozzle inner when you push the nozzle slider in the direction indicated with the arrow mark) with a cotton swab whose half part is dampened with oil.
3, Move the nozzle slider up and down twenty to thirty times to spread oil over the entire nozzle slider.
4, Wipe off excessive oil around the nozzle with clean waste cloth.
