Stopping the Engine

Usage:

395 LTK


注意

在负荷下工作后立即将发动机熄火会造成发动机过热和发动机部件的加速磨损。

参考以下步骤,使发动机冷却,并防止涡轮增压器壳体出现过高温度而引起油的焦化问题。



注意

发动机运转时决不可将蓄电池断路开关转到“断开”(OFF)位置。 否则会导致电路系统严重损坏。


  1. 将机器停放在平地上。 有关推荐的程序,请参阅操作和保养手册, "停止机器"。

  2. 机器停止后,低怠速运转发动机 5 分钟。 怠速运转发动机可使发动机的高温区域逐渐冷却。

  3. 把发动机起动开关转到断开位置,拔出钥匙。

    注: 如果"主动再生"指示灯点亮,不要关闭发动机。 有关指示灯的更多信息,请参阅操作和保养手册, "监控系统"。

发动机的停机控制

将发动机起动开关转到断开位置。 如果发动机不停机,应执行下列步骤。

注: 务必使用发动机起动开关停止发动机。 将发动机停机控制装置用作起动开关故障时停止发动机的替代方法。

  1. 开关位于驾驶座椅左侧的下面。

  2. 提升罩盖 (1)。

  3. 将开关 (2) 往上拨。 这样会停止发动机并防止发动机再次起动。

  4. 将开关返回原位。 发动机应能够起动。

    注: 在故障未排除之前不要再操作机器。

  5. 如果上述的步骤不能停止发动机,应使用以下方法。

如果发生电气故障应关闭发动机

将发动机起动开关转到断开位置。 如果发动机不停机,应执行下列步骤。

燃油切断阀位于右侧检修门后面。

顺时针转动燃油切断阀 (3),将燃油供应切断。 在燃油管道中的燃油消耗掉之后,发动机就会停机。 发动机可能持续运转几分钟。

重新起动发动机之前要修理好发动机。 燃油系统可能需要充油。 请参考操作和保养手册, "燃油系统 - 注油"中的说明。
