The hydraulic oil replacement interval of Carter excavators is one of the key maintenance links to ensure the performance and life of the equipment. As the core part of the excavator, the working efficiency and stability of the hydraulic system depend to a large extent on the quality of the hydraulic oil. Typically, the frequency of hydraulic oil changes on a Carter excavator is affected by a variety of factors, including the working environment (e.g., temperature, dust pollution level), working load (continuous working time, work intensity), and the quality level and oxidation resistance of the hydraulic oil itself. Under the general industrial recommendation standard, for the Carter excavator under normal working conditions, it is recommended to change the hydraulic oil every 2000 hours or every year, but this is not fixed and needs to be flexibly adjusted according to the actual situation. The user should regularly test the hydraulic oil, and when it is found that the hydraulic oil is black, turbid or contains foreign objects such as metal shavings, even if the specified working hours are not reached, the hydraulic oil should be replaced in time to prevent potential damage to the hydraulic system. To maximize the life of your excavator and keep it running efficiently, it's important to follow the manufacturer's maintenance guidelines and incorporate the recommendations of a professional technician to develop a proper hydraulic oil change schedule. In summary, the specific time point of the replacement of hydraulic oil of Carter excavator needs to be comprehensively judged according to the actual use of the equipment, and the timely replacement can not only effectively protect the hydraulic system, but also ensure the smoothness and durability of the overall operation of the excavator.
