Where is the pressure adjustment in Futian Ou Ma?

Where is the air pressure adjustment in Futian Ou Ma? The solution is as follows. Found the dryer in the front of the truck. The function of dryer is to remove moisture from the air and provide clean air for the pneumatic system of truck. Below the dryer is an air pressure regulator, which is used to adjust the air pressure. After finding the air pressure regulating valve, don't directly adjust it first. First, observe the barometer to ensure that the air pressure is below six pressure values. For beginners, if they don't know how to adjust the pressure, it is easy to have excessive pressure, and the explosion of the air reservoir is very dangerous. After the preparatory work is completed, clamp the adjusting screw of the air pressure regulator with a wrench and turn the adjusting screw of the air pressure regulator clockwise for one turn, so that the system exhaust pressure will increase by 1. We can turn the adjusting screw of the air pressure regulator counterclockwise, and the exhaust pressure of the system will rise and fall 1. The air pressure in the factory is 8 atmospheres. Test the internal air pressure. When traveling, it is usually 9 atmospheres. Therefore, according to the pressure gauge, the torque wrench is adjusted to the air pressure specified by the system.
