To use an ARB Digital Inflator, simply:

1. Clip on your Digital Inflator to your air compressor using your ARB Inflation Kit.
2. Remove your tire valve cap.
3. Connect the valve connector to the tire valve of the tire you want to inflate.
4. After being connected to the valve, the Digital Deflator will sense air pressure and automatically turn on. Displayed on the monitor will be a real-time pressure reading of your tire.
5. To inflate simply press down on the inflation handle with your thumb.
6. If you need to deflate, press the deflation button to the left of the inflation handle.

ARB's analog gauge operates with the same protocol, but does not need to be powered on.
