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

接触高压燃油可能导致液体渗透和烧伤危险。 高压燃油溢出可能会产生火灾。 如果不遵循检查、保养和维修指南,可能会造成人身伤亡。


在进行调整和修理前,请参阅操作和保养手册, "一般危险信息和高压燃油管路"。

注: 有关在所有燃油系统工作期间必须遵循的清洁度标准的详细信息,请参阅系统运作, "燃油系统部件清洁度"。

确保所有的调整和修理由经过适当培训的授权人员来执行。


注意

持续盘车不要超过30秒。 再次盘车前,让起动马达先冷却2分钟。


如果空气进入燃油系统,在发动机起动前,必须排除燃油系统的空气。 发生以下事件时,空气可能会进入燃油系统:

  • 燃油箱排空或燃油箱部分排放。

  • 断开低压燃油管。

  • 低压燃油系统存在泄漏。

  • 已更换燃油滤清器。

手动燃油注油泵

按照以下步骤,排出燃油系统中的空气:
