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

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。


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

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。



注意

在进行检验、保养、测试、调整及维修产品期间,必须小心以确保装好排放出的油液。 在打开任何舱室或解体任何储有液体的部件之前,要准备好合适的容器收集液体。

有关收集和盛接 Cat 产品上油液的适用工具和用品,请参阅专门出版物, NENG2500, "代理商维修工具目录"。

按照当地法规和要求处置所有液体。

变速箱滤清器底座上有滤清器进口和冷却器出口测压口。 参考图 2。 进口测压口同时还是两用定期油取样(SOS)口(带有紫色防尘罩)。 在为 SOS 进行油品取样时采用此端口。 为了防止损坏端口内的密封并由此引发泄漏,在使用油液取样口时务必采用 169-8373 油液取样瓶。

按照以下程序获取 SOS 油样。

  1. 起动发动机。 加热机油,直至油位达到 47° C (116° F)

  2. 确保变速箱控制装置处于空档位置并将油门置于低怠速位置。

  3. 卸下防尘盖。 使用 169-8373 油液取样瓶从 SOS 口获取油样。

  4. 停止发动机。

  5. 检查液压滤清器滤芯中有无异物。

  6. 更换液压滤清器滤芯。

有关计划油样和计划油样分析的更多信息,请参考变速箱操作和保养手册, "S·O·S 信息"。

请参考专门出版物, PEHP6001, "如何获取良好油样"以了解有关获取油样的更多信息。

关于为设备建立 SOS 计划的详细资料和协助,请咨询您的 Caterpillar 代理商。
