The selection of suitable hydraulic fluids for hydraulic system maintenance by Cat excavators is essential to ensure that they meet standard requirements.Hydraulic fluids not only affect the overall performance and efficiency of excavators, but also have a direct impact on the life of the equipment.For Cat excavators, hydraulic fluids should have appropriate viscosity, good resistance to oxidation and excellent resistance to wear and tear.In general, hydraulic oil specifications recommended by Cat excavators will vary according to the specific type of aircraft, but generally need to meet ISO 46 or ISO68 standard levels, and users are advised to obtain accurate hydraulic oil specifications and replacement cycle information by reference to official manuals provided by equipment manufacturers.At the same time, in working-temperature zones of hydraulic fluids, the viscosity index (VI) should be within the range recommended by the manufacturer to ensure that the hydraulic system works normally under various conditions.In order to ensure the clean and efficient operation of hydraulic systems, it is also important to check regularly the quality of hydraulic fluids, including by observing the depth of the colour of hydraulic fluids, the presence of metal particles or other impurities, which is an important basis for determining whether hydraulic fluids need to be replaced.In summary, the selection and use of hydraulic fluids for the Cat excavator requires strict official guidance to ensure that the quality of hydraulic fluids is met and that the actual needs for machine operations are met in order to effectively extend the life of the excavator, reduce failure rates and improve operational efficiency.
