(1) 维修指示器

某些发动机可能装有不同的维修指示器。

观察维修指示器。 发生下列情况时,清洁或更换空气滤清器滤芯:

  • 维修指示器窗口变红。

  • 空气阻力达到 6.2 kPa (25 in H2O)。

测试保养指示器

维修指示器是重要的仪器。

检查复位是否容易。 维修指示器在三次以下的按下尝试后应当复位。如果维修指示器不容易复位,应更换维修指示器。 如果新的维修指示器也不能复位,则维修指示器的接头可能已堵住。

如有必要,在严重多尘的环境下,维修指示器需要频繁地更换。 不管运转情况如何,每年都要更换维修指示器。 发动机大修和更换主要发动机部件时,更换维修指示器。

注: 安装新的维修指示器时,拧得过紧可能使维修指示器顶部开裂。 拧紧维修指示器至扭矩为 2 N·m (18 lb in)。
