Campell Hausfeld compressor
Prior to turning the unit "on", i turn the regular counter-clock wise all the way to the left. I then set the regulator to 40 pounds air pressure. I'm pumping up a tire. The tank guage continues to climb to 40 pounds. I connect the tire air guage - connected directly to the air hose on the CH unit - to the tire. The regulator guage shows the current tire pressure but no air is passing through the compressor in to the tire. Am I missing something?
