The circular paper that lists the PSI level in my gauge has come somewhat dislodged. Anyone know how to open up the gauge so I can attempt to put it back in place? Can't seem to figure it out. See pic below.
Mine came off fairly easy. I didn't have to use any tools. I bent the metal back as normal as I could get it then put the clear plastic piece back on. Good luck, hope that it works out for you!
Some of mine come off with a very small twist, the plastic lens has 2 little nubs on it that twist lock into the metal housing. They only turn about 1/8 inch. Aslo have a couple that the plastic cover is threaded and screws on.
