安县晴空滤芯厂生产的液压油滤芯保养方法如下：

1.换前先放掉原有液压油，检查回油滤芯，吸油滤芯，先导滤芯，看是否附有铁屑铜屑或其他杂质，有的话可能有液压元件故障，检修排除后，清洗系统。

2.换液压油时须同时更换所有液压油滤芯(回油滤芯，吸油滤芯，先导滤芯)，否则相当于没换。

3.辨别液压油标号，不同标号、不同品牌的液压油不混用，可能会起反应变质产生絮状物。推荐用该挖掘机指定用油。

4.加油前必须先装上吸油滤芯，吸油滤芯罩着的管口直接通向主泵，进了杂质轻则加速主泵磨损，重则打泵。

5.加油至标准位置，液压油箱上一般都有油位表，看液位表。注意停放方式，一般是所有油缸全部收回，即小臂、铲斗完全伸出并落地。

6.加完油后注意主泵要排空气，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，直接加满即可固安县晴空滤芯厂
