进行此一保养时，要确保发动机不会被起动。 不要使用起动马达来旋转飞轮，以免造成人身伤害。 热的发动机零部件可能造成烫伤。 在测量/调整单体喷油器前要等一定时间，让发动机冷下来。 电子单体喷油器采用高电压。 断开单体喷油器的电路接头以防止人身损伤。 发动机运转时，不要接触喷油器接线端。 |
在电子单体喷油器调整不当的情况下运行 Cat 发动机可能降低发动机的效率。 这种效率降低将导致燃油用量过大和/或发动机部件寿命缩短。
只有具有资质的维修人员才能执行此项保养。 请参阅下述主题中有关发动机的正确步骤：请参阅系统操作、测试和调整, "电子单体喷油器 - 测试"中的测试步骤，以及系统操作、测试和调整, "电子单体喷油器 - 调整"中调整喷油器的正确步骤。

在对燃油喷油器进行间隙调整之前，凸轮轴相对于曲轴的正时必须调整正确。 旋转曲轴之前，正时销必须从凸轮轴上取下来，否则将会对缸体造成损坏。 |
