1300R020BN4HC/-V-KB滤芯***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。1300R020BN4HC/-V-KB滤芯性能指标：过滤精度：1～100μm工作压力（MAX）：21MPa工作介质：一般液压、磷酸脂液压油、乳化液、水-乙二醇工作温度：-30℃～+110℃1300R020BN4HC/-V-KB1300R003BN,1300R003BN/-V,1300R003BN3,1300R003BN3/-V,1300R003BN3HC,1300R003BN3HC/-B6,1300R003BN3HC/-KB,1300R003BN3HC-S0105,1300R003BN3HC/-S062,1300R003BN3HC/-V,1300R003BN3HC/-V-KB,1300R003BN3HC/-V-S0105,1300R003BN3HC/-V-S062,1300R003BN3HC/B4-KE50,1300R003BN3HC/-V-B4-KE50,1300R003BN4HC,1300R003BN4HC/-B6,1300R003BN4HC/-KB,1300R003BN4HC/-S0105,1300R003BN4HC/-S062,1300R003BN4HC/-V,1300R003BN4HC/-V-KB,1300R003BN4HC/-V-S0105,1300R003BN4HC/-V-S062,1300R003BN4HC/B4-KE50,1300R003BN4HC/-V-B4-KE50,1300R003BNHC,1300R003BNHC/-B6,1300R003BNHC/-S062,1300R003BNHC/-V,1300R003BNHC/-V-S0105,1300R003BNHC/-V-S062,1300R003ECO/N,1300R003ECO/N/-V,1300R003/-V1300R005BN,1300R005BN/-V,1300R005BN3,1300R005BN3/-V,1300R005BN3HC,1300R005BN3HC/-B6,1300R005BN3HC/-KB,1300R005BN3HC-S0105,1300R005BN3HC/-S062,1300R005BN3HC/-V,1300R005BN3HC/-V-KB,1300R005BN3HC/-V-S0105,1300R005BN3HC/-V-S062,1300R005BN3HC/B4-KE50,1300R005BN3HC/-V-B4-KE50,1300R005BN4HC,1300R005BN4HC/-B6,1300R005BN4HC/-KB,1300R005BN4HC/-S0105,1300R005BN4HC/-S062,1300R005BN4HC/-V,1300R005BN4HC/-V-KB,1300R005BN4HC/-V-S0105,1300R005BN4HC/-V-S062,1300R005BN4HC/B4-KE50,1300R005BN4HC/-V-B4-KE50,1300R005BNHC,1300R005BNHC/-B6,1300R005BNHC/-S062,1300R005BNHC/-V,1300R005BNHC/-V-S0105,1300R005BNHC/-V-S062,1300R005ECO/N,1300R005ECO/N/-V,1300R005/-V1300R010BN,1300R010BN/-V,1300R010BN3,1300R010BN3/-V,1300R010BN3HC,1300R010BN3HC/-B6,1300R010BN3HC/-KB,1300R010BN3HC-S0105,1300R010BN3HC/-S062,1300R010BN3HC/-V,1300R010BN3HC/-V-KB,1300R010BN3HC/-V-S0105,1300R010BN3HC/-V-S062,1300R010BN3HC/B4-KE50,1300R010BN3HC/-V-B4-KE50,1300R010BN4HC,1300R010BN4HC/-B6,1300R010BN4HC/-KB,1300R010BN4HC/-S0105,1300R010BN4HC/-S062,1300R010BN4HC/-V,1300R010BN4HC/-V-KB,1300R010BN4HC/-V-S0105,1300R010BN4HC/-V-S062,1300R010BN4HC/B4-KE50,1300R010BN4HC/-V-B4-KE50,1300R010BNHC,1300R010BNHC/-B6,1300R010BNHC/-S062,1300R010BNHC/-V,1300R010BNHC/-V-S0105,1300R010BNHC/-V-S062,1300R010ECO/N,1300R010ECO/N/-V,1300R010/-V1300R020BN,1300R020BN/-V,1300R020BN3,1300R020BN3/-V,1300R020BN3HC,1300R020BN3HC/-B6,1300R020BN3HC/-KB,1300R020BN3HC-S0205,1300R020BN3HC/-S062,1300R020BN3HC/-V,1300R020BN3HC/-V-KB,1300R020BN3HC/-V-S0205,1300R020BN3HC/-V-S062,1300R020BN3HC/B4-KE50,1300R020BN3HC/-V-B4-KE50,1300R020BN4HC,1300R020BN4HC/-B6,1300R020BN4HC/-KB,1300R020BN4HC/-S0205,1300R020BN4HC/-S062,1300R020BN4HC/-V,1300R020BN4HC/-V-KB,1300R020BN4HC/-V-S0205,1300R020BN4HC/-V-S062,1300R020BN4HC/B4-KE50,1300R020BN4HC/-V-B4-KE50,1300R020BNHC,1300R020BNHC/-B6,1300R020BNHC/-S062,1300R020BNHC/-V,1300R020BNHC/-V-S0205,1300R020BNHC/-V-S062,1300R020ECO/N,1300R020ECO/N/-V,1300R020/-V1300R010P,1300R010P/-V,1300R010P/HC,1300R010P/HC-KB,1300R010P/HC-KB-V,1300R010P/HC-V,1300R025W1300R025W-S062,SBF1300RZ05V,SBF1300RZ10B,SBF1300RZ10V,SBF1300RZ25B,SBF1300RZ25V,SBF1300RZ3B,SBF1300RZ5B,1300R025W-V,1300R025W/-V-S062,1300R025W/HC,1300R025W/V-KB,1300R025WHC,1300R025WHC/-V,1300R025WHC/-V-KB,1300R025WHC,1300R025WHC/-V,1300R025WHC/-V-KB,1300R040HC,1300R040HC-KB,1300R040HC-KB-V,1300R040HC-V,1300R040HC/V,1300R050W/HC,1300R050W/HC-V,1300R074W,1300R074W-V,1300R074WHC,1300R074WHC-V,1300R149W,1300R149W-V,1300R149WHC,1300R020BN4HC/-V-KB)
