增压系统: 热的冷却液能造成严重的烫伤。 为了打开盖子,要停机,等候散热器冷下来。 然后慢慢松开盖子,释放压力。



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。



注意

将 卡特彼勒 长效性冷却液加上或混和其它不符合 卡特彼勒 EC-1 技术规格的冷却液会降低冷却液的功效和缩短冷却液的工作寿命。

对于预混合或浓缩的冷却液,只能使用卡特彼勒 产品或符合卡特彼勒EC-1 规格的市售产品。 所有的延长剂只能是卡特彼勒 ELC。

不遵循这些建议会缩短冷却系统零部件的寿命。


参考关于向冷却系统中添加延长剂的资料,见操作和保养手册, "冷却系统冷却液的延长剂(ELC)- 添加",或者向 Caterpillar 代理商咨询。

如果原先使用的是长效冷却液,就需要用清水把冷却系统冲洗干净。 不需要其他的清洁剂。 使用下述程序来更换长效冷却液。
