Remove the air stem from your lantern's check valve in order to determine which of the two threaded rods to use (8-32 or -32 thread) 2. Hand screw the rod into the check valve at least finger tight. Engage as much thread as possible. 3. Slide the tube down over the rod. 4. Make sure that the ears are fully engaged in the slot. Gently turn the tube until the ears drop into the slots cut in the check valve. 5. Drop a washer onto the rod and then screw on the wing nut(1/4-20 thread) and tighten just enough to eliminate any play in the tube and lock it into place. Caution: Do not over tighten as the brass threads in the check valve may strip! 6. Using adjustable wrench, fit it to the flats on the exposed end of the tube. 7. Hold the fount in a solid grip. If you have a vise, this is a great application for it. Give the wrench a solid turn counterclockwise. Do not side load the wrench. The check valve will loosen and you will be able to remove the entire assembly with the check valve attached. 8. Clean and loosen the ball bearing in the check valve and when free, screw the check valve back into the fount, or use a new replacement valve, we offer replacement check valves and other parts. 9. As Always, Check for Leaks. Place empty Font, Lightly Pressurized with air, submerged in water. Look for air bubbles. Or use A Font Pressure Gage. 10. Be careful not to reinstall the valve too tight! 11. It's also a good idea to lightly coat the tool with oil as it can rust in a damp environment.
