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

压力下飞溅的油液,会造成人员伤亡。

带有压力的渗漏液体可能会穿透人体组织。 液体穿透进入身体会造成严重的人身伤害,甚至可能导致死亡。 即使是一个针孔大小的漏洞,也可能会引起严重的人身伤害。 如果液体喷射穿透您的皮肤,必须立即找熟悉这类型创伤的医生处置。

请使用木板或硬纸板作为挡板来检查渗漏。


------ 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,在测试和调整液压系统之前,遵照以下程序:



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。


  1. 将机器放在光滑、水平的表面上。 远离其它运转机器和人员。 将铲斗和/或附件降至地面。 关闭发动机。

  1. 机器上仅允许停留一位操作员。 让其他人员远离车辆或离开操作人员的视野。

  1. 接合停车制动器。 轮子前后都塞上垫块。

  1. 在升起铲斗和/或附件进行测试或调整时,务必正确支撑铲斗和/或附件。

    注: 除非测试特别需要,否则停放机器时,不要使机器前端脱离地面。 将机器降至地面并停运发动机。

  1. 通过连接转向机架锁使机器不能铰接。

  1. 将发动机启动开关转到 ON 位置。 将机具锁定开关置于解锁位置。

  1. 在所有位置循环移动液压操纵杆,以释放液压系统内的压力。 将提升操纵杆放在浮动位置。

  1. 将发动机起动开关转到断开位置。

  1. 要想完全释放液压油箱内的压力,推入断路器安全阀上的柱塞,直到所有液压力得以释放。

    注: 也可以拆下液压油箱加注口盖,但使用断路器安全阀上的柱塞是比较安全的油箱卸压方法。
