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

高压喷射流体可造成人员伤亡。

高压喷射流体,即使是针孔大小的泄漏,也能穿透人体组织并造成严重的人员伤亡。 如果流体射入皮肤,必须立即寻求熟悉此类创伤的医生进行救治。

检查泄漏时,务必随身携带木板或硬纸板。


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

突然移动车辆或释放油压会伤害车上或附近的人员。

为避免可能造成的伤害,在测试和调整制动系统之前,执行以下步骤。



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。
