贴士1:使用高等级油品按照厂商规定时间更换机油,是确保挖掘机性能和使用寿命的基本条件。发动机油尤其是含添加剂的机油,在高负荷循环工作时容易发生分解。使用劣质或黏度不当的机油,会缩短发动机使用寿命,并产生高昂的维修费用。安装废气再循环和颗粒捕捉装置的新型Tier4发动机,要求使用优质高等级机油。优质机油杂质含量低,不仅有助于提高发动机耐磨防护性 Tip 1: The use of high-grade oil in accordance with the provisions of the manufacturer’s time to replace the oil, excavator is to ensure the performance and service life of the basic conditions. Engine oils, especially those containing additives, are prone to decompose during high duty cycle operation. Use of inferior or improper viscosity of the oil, will shorten the life of the engine, and generate high maintenance costs. The new Tier 4 engines with exhaust gas recirculation and particulate capture units require the use of premium high grade oil. High quality oil impurities low, not only helps to improve the wear resistance of the engine
