How To Inflate/Deflate Tires Using The Viair Automatic Portable Air Compressor
Question:
Would be helpful to see a video demonstrating how well this inflator actually works filling a few tires, instead of just hooking up the battery cord and hose and stretching it out and running the pump for a few seconds. For example, how do you start/stop inflation to get to a target psi when the only on/off switch is back at the pump 30-feet away? Does automatic shutoff work only if the chuck is not engaged to the valve stem?

I went ahead and checked the owner's manual for the Viair Automatic Portable Air Compressor # VA29WR and they state that the compressor is equipped with built-in pressure switch with a factory set cut-on pressure of 130 PSI (± 5%) and a factory set cut-off pressure of 155 PSI (± 5%). During inflation of tire pressures between 130 PSI to 155 PSI, if you stop inflation, the compressor may not restart.
However, this is completely normal, since inline pressure is greater than cut-on pressure of the pressure switch and less than cut-off pressure of the pressure switch.
To restart compressor, deflate tire pressure to below 130 PSI, reconnect tire chuck to tire valve stem and resume tire inflation.
To inflate tires:
1. Attach one end of the extension coil hose to the compressor and the other end to the tire gun kit.
2. Push the tire chuck, with the lever in the upright position, down over the tire valve stem and then push the lever down to the horizontal position to lock in place.
3. Turn compressor switch on and hold down the trigger on the tire gun kit to begin inflation.
4. When desired pressure is reached, release the trigger and turn power switch on compressor off.
To release excess pressure turn off compressor and disconnect hose from compressor. With the tire inflation gun still connected to the other end of the coil hose, pull trigger on the tire inflation gun to release excess pressure.
Finally, to deflate tires push the tire chuck (with the lever in the upright position) down over the tire valve stem and then:
1. Push the lever down to the horizontal position to lock in place.
2. Press the bleeder valve button on the tire gun kit to decrease tire pressure.
3. When desired pressure is reached, release the bleeder valve button to halt deflation.
