------ WARNING! ------

吊装或垫塞不当可能会造成人员伤亡。

当使用起重机或千斤顶顶升任何零件或部件时,与之保持距离。 确保起重机或千斤顶具备正确的部件吊装能力。 在沉重部件下面进行任何工作之前先安装垫块或台架。

图上显示的是部件的近似重量。 清洁要安装零件的所有表面。



注意

在检验、保养、测试、调整及维修产品时,务必留心,确保液体盛装在容器中。 在打开任何腔室或拆解任何储有液体的部件之前,要准备好用合适的容器收集液体。

有关适合收集和盛接卡特彼勒产品上液体的工具及用品,参考专门出版物, NENG2500, "卡特彼勒工具和修理车间设备指南"。

按照当地法规和指令处置所有液体。


  1. 在所有管路、软管、导线及管上作识别标记,以便于安装。 插接好所有线路、软管和管路。 这将有助于防止液体泄漏和有助于防止机油系统污染。
