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

渗漏或溅溢到热表面或电气部件上的燃油会引起失火。 为防止可能的伤害,当更换燃油滤清器或油水分离器滤芯时,要将起动开关断开。 应立即将溅溢的燃油清除干净。


如果发动机燃油系统在运转时油量不够,加注燃油箱。 向燃油系统注油以去除系统中的气泡。


注意

不要拧松燃油歧管处的燃油管路。 当燃油管路松开时,发动机部件可能损坏和/或注油压力可能损失。

典型实例

按照以下步骤充注燃油系统:

  1. 定位燃油充油泵。

  1. 通过操作注油泵的柱塞 (1) 加注燃油细滤器。 继续泵送直到感觉到有阻力。

    注: 可能需要推动充油泵 25 次或以上以便加满燃油滤清器。 另外,可能需要推动充油泵多达 75 次以加满燃油供油道。

  1. 推入柱塞并顺时针拧紧柱塞。 用手拧紧柱塞。

  1. 加压燃油系统后,立即盘车起动发动机。

    注: 使用发动机起动步骤。 请参阅操作和保养手册, "发动机起动"(操作章节)。
