The foot pedal is for pumping up. Often there is a lowere function when the pedal is held down.Thanks for the responses. The other sticker is just warnings, no identification. I just looked up Lincoln, I don't see anything similar, the letters don’t seem to line up on the sticker either. It definitely has an “N”. I need to see how I can adjust / repair the knob. There is no foot released, so it is slow going down.
