When the Carter excavator is operating normally, its air pressure parameter is one of the key factors to ensure the efficient and stable operation of the equipment. Generally speaking, the air pressure of the main system of the Carter excavator should be maintained between 8.5-10kg/cm², which is considered to be the normal working range of the air pressure of the Carter excavator. However, please note that the standard air pressure of different models and excavators under different working conditions may be different, so it is recommended to refer to the factory instructions of specific models for setting and adjustment. In order to ensure the performance and longevity of the excavator, the operator needs to check regularly and ensure that the air pressure system is stable and accurate. In daily maintenance, it is necessary not only to pay attention to whether the air pressure value is within the normal range, but also to pay attention to the changes in the reading of the barometer, so as to find potential problems in time and prevent various failures caused by abnormal air pressure. To sum up, it is important for Carter excavators to understand and master the correct air pressure standards and reasonable maintenance methods to ensure that the machine is always in top working condition.
