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

热的冷却液、蒸汽和碱会造成人身伤害。

在工作温度下,发动机冷却液是热的而且处在压力下。 散热器和所有到加热器的管路或发动机中都有热的冷却液或蒸汽。 与它们的任何接触都会造成严重烫伤。

只有当发动机停机且冷却系统压力盖已经冷却到可以徒手触摸时,再慢慢拆下冷却系统压力盖以释放压力。

不要试图在冷却液还热的时候去拧紧软管接头,软管会脱落而造成灼伤。

警告:冷却系统的冷却液添加剂含碱。 应避免它与皮肤和眼睛接触。



注意

保持所有零件清洁无杂质。

杂质会造成快速磨损和缩短部件寿命。



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。
