How to adjust the truck barometer?

1. First find the dryer at the front of the truck.

2. Secondly, after finding the air pressure regulating valve, don't adjust it directly. Observe the barometer first to ensure that the air pressure does not exceed 6 pressure values.

3. After the final preparation, clamp the adjusting screw of the air pressure regulator with a wrench, and turn the adjusting screw of the air pressure regulator clockwise by 1 turn, so that the exhaust pressure of the system rises by 1. Turn the adjusting screw of the air pressure regulator 1 turn counterclockwise, and the system exhaust pressure will rise 1. Generally, the air pressure at the factory is 8. Test internal air pressure. The displacement is usually 9 atmospheres. According to the pressure gauge, turn the wrench to adjust to the air pressure specified by the system.
