I got the Cat at 12 noon today. I fired it up for the first time at 6 o'clock. Everything went perfect on the ramp up, the green light came on and I had throttle control. It ran for a minute or so before I realized that the 3 position switch was still in the middle (standby-start) position. I switched it to run and the turbine revved up alittle before shutting down. The display said (auto shut down). Are you supposed to move the 3 position switch to the run position at another time? I started it again and everything ran perfect if I left it in the middle. Cool down and everything else went normally. Help please?
