So I had just left the mill after unloading my Redwood logs, heading back out to the forest. My dash lite up red and was screaming at me with its alarm. My pressure gauges on both the first and secondary tanks were at 60 lbs. After pulling to the side of the highway i set my brakes and throttled up. The gauges moved up in pressure and alarms turned off. I headed back out after doing a complete walk around check and found to leaks, hissing or noises that would point to the reason. I made the rest of the day without incident. What would have caused the issue.
Inexplainable Loss of air
