有关变速箱液压系统的所有检查和测试,请参考以下警告和测压口位置。 如果问题的范围未知,按照提供的顺序执行测试。 对于所有测试,如果问题的范围未知,机油必须处于正常工作温度。

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

机器的突然动作或在压力下放油,可能对机器上或机器附近人员造成伤害。 为避免可能造成的伤害,在进行测试前执行以下步骤。


  1. 把机器开到平整水平的地方。 移到远离工作的机器和人员的地方。

  1. 将变速箱前进档/倒档换向控制置于空档 位置。

  1. 激活空档锁定开关。 停止发动机。

  1. 机器上仅允许停留一位操作员。 让所有人员远离机器或在操作人员的视野范围内。

  1. 启动停车制动器。

  1. 将铲斗(装载机和反铲)降至地面。 将稳定器降至地面。

  1. 部件调整前,务必释放所有液压压力。

故障的检查和排除也许很困难。 下几页中列出了一些可能的故障和解决方法。

故障和解决方法列表只指示故障类型和所需的修理。 通常情况下,在列表建议之外还需要更多维修工作或其他维修工作。 本列表不能提供所有可能出现的故障和排除方法。 维修人员必须要找到故障和故障的源头。 然后,维修人员必须进行必要的修理。

首先进行目视检查。 检查机器的运行情况,然后用器具检查。
