油站滤芯HC9700FDT27Z液压油滤芯保护方法如下：

1.换前先放掉原有液压油，查看回油滤芯，吸油滤芯，先导滤芯，看是不是附有铁屑铜屑或别的杂质，有的话或许有液压元件缺陷，修补清扫后，清洗系统。2.换液压油时须一起更换全部液压油滤芯(回油滤芯，吸油滤芯，先导滤芯)，否则相当于没换。
3.区别液压油标号，不一样标号、不一样品牌的液压油不混用，或许会起反响蜕变发作絮状物。举荐用该开掘机指定用油。
4.加油前有必要先装上吸油滤芯，吸油滤芯罩着的管口直接通向主泵，进了杂质轻则加快主泵磨损，重则打泵。
5.加油至规范方位，液压油箱上通常都有油位表，看液位表。留神停放方法，通常是全部油缸全部回收，即小臂、铲斗完全伸出并落地。
6.加完油后留神主泵要排空气，否则轻则暂时全车无动作，主泵异响(空气音爆)，重则气穴损坏主泵。排空气方法是直接在主泵顶部松开管子接头，直接加满即可。
