Daily Cleaning Procedure (cont.)
Note: The best way to remove an “O” Ring is to first wipe off all of the lubricant using a clean paper towel. Pinch the “O” Ring upward with a dry towel between your index finger and thumb. When a loop is formed in the “O” Ring, roll it out of the groove with your other thumb. Always remove the “O” Ring farthest from
the end of the plunger first. (See figure M).
