即使是从针孔大小的渗漏中漏出的空气或液体，都能够穿透人体组织而造成严重创伤，甚至死亡。 如果液体喷射穿透进您的皮肤，必须立即找熟悉这类型创伤的医生处置。 检查渗漏时，请务必使用木板或硬纸板作为挡板。 |

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。 |

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。 |
如果油受到污染，可能会造成部件的早期故障。 受到污染的油也会引起过热。
采用以下程序确定液压系统中油的污染程度。
- 检查液压滤清器滤芯中有无异物。
- 青铜色颗粒说明泵或马达配流盘发生故障。
- 闪亮的钢颗粒说明泵或马达活塞发生故障。
- 橡胶颗粒物说明密封或软管发生故障。
- 铝颗粒说明转向和/或充油泵发生故障。
注: 如果在液压滤清器滤芯中发现这些颗粒物中的任意一种，则必须清洁液压油系统的所有部件。 不要使用任何损坏的零件。 必须卸下损坏的零件并安装新零件。
