2. Adjusting Output Pressure
The compressor features a pressure regulator to control the air pressure delivered to your tools.
- Attach your air hose and tool to one of the quick-connect valves.
- Turn the pressure regulator knob (usually located near the output gauges) clockwise to increase pressure and counter-clockwise to decrease pressure.
- Monitor the output pressure gauge to set the desired pressure for your application.
