------ 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。

卸下液压系统的部件或管路时,确保所有的作业机具都已降到地面上,而且液压油温度已冷。 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

在检查、保养、测试、调整及维修产品时,请小心确保盛接油液。 在打开任何舱室或拆卸任何含有油液的部件前,请准备好盛接液体用的适当容器。

有关收集和盛接 Cat® 产品油液的合适工具和用品,请参阅专门出版物, PERJ1017, "代理商维修工具目录"。

按照本地法规和要求处置所有油液。


简介

按照以下步骤排除辅助泵和 PTO 驱动装置内的空气。

注: 在排除辅助泵和 PTO 驱动装置内的空气之前,确保液压主泵和风扇泵已正确注满液压油,以免系统损坏。 有关详细信息,请参阅操作和保养手册 , 主液压泵空气 - 排气和液压系统空气 - 排气(风扇泵)。
