在检验、保养、测试、调整及维修发动机时，请小心确保盛接流出的液体。 在打开或拆解任何储有液体的部件之前，要准备好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的液体的工具和供应品，请参阅专门出版物, NENG2500, "卡特彼勒代理商工具目录"。 按照本地法规和条例处置所有液体。 |
- 把机器开到平整水平的地方。 远离其它机器和所有人员。 将所有选装部件降至地面。 将铲刀提升阀的操纵杆置于浮动位置。
- 在前轮轴上安装轮子倾斜锁定螺栓。 安装机架锁定销子。 接合停车制动器，然后关闭发动机。
- 机器上仅允许停留一位操作员。 其它人员远离机器。 而且，操作员要能看到所有人员。
- 轮子前后都垫上楔子。
- 执行以下任一程序之前，确保所有液压已全部释放。
- 松开所有的连接件，软管或其它部件。
- 拧紧所有的连接件，软管或其它部件。
- 拆卸所有的连接件，软管或其它部件。
- 调整所有的连接件，软管或其它部件。
- 松开所有的连接件，软管或其它部件。
- 系统里的压力释放完毕后，仔细把连接件松开，并取下管路和部件。
