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。 |

滚热的油或液压油的压力会对人员造成伤害。 发动机停机之后，液压油的压力仍会保留在液压系统里。 对液压系统进行维修之前，如果不事先释放压力，可能会造成严重伤害。 卸下机具和其油路之前，必须先把机具放到地面上，让油先冷却，才可进行工作。 只能在发动机停机，并且加注口盖冷却到可以用徒手触摸时才能卸下加注口盖。 |
注: 在软管组件上标上识别标记，以用于安装目的。 插上软管组件。 这将有助于防止液体泄漏和污染物进入系统。
注: 清洁度是一项重要的因素。 拆卸步骤开始之前，应彻底清洁部件外部。 这有助于防止尘土进入内部结构。
注: 转向计量泵位于驾驶室前侧下方位置。
