1. Adjust the air pressure regulator adjustment knob by turning it counter clockwise to drop air pressure and clockwise to increase air pressure.
2. Check the manufacturer guide for the tools you are planning to use with this unit once it has reached full pressure. The guide will properly inform you which tools can be used with the unit. 3. Get a sighted person to tell you what pressure is operating and by turns from fully open or fully shut remember the turns it takes to get to that pressure. 4. Remember you will have to be running that air tool while adjusting the pressure regulator. 5. You might like to start adjusting from no pressure up to the desired pressure sort for that tool. 6.
