典型保养指示器

观察保养指示器。 发生以下情况之一时,应清洁或更换空气滤清器滤芯:

  • 黄色膜片进入红色区域。

  • 红色柱塞锁定在可见位置。

测试保养指示器

保养指示器是重要仪器。

  • 检查复位是否灵活。 保养指示器应在少于 3 次按压的情况下复位。

  • 发动机加速到发动机的额定转速时,检查黄芯的移动情况。 黄芯应大致锁定在可以达到的最大真空位置。

如果保养指示器不燃油复位或黄芯无法锁定在最大真空位置,应更换保养指示器。 如果新的保养指示器也不能复位,则保养指示器的安装孔可能堵塞。

如有必要,在严重多尘的环境下,保养指示器可能需要频繁更换。 不管运转情况如何,每年都要更换保养指示器。 发动机大修和更换主要发动机部件时,更换保养指示器。

注: 安装新的保养指示器时,拧得过紧会使保养指示器顶部开裂。 拧紧保养指示器至扭矩2 N·m (18 lb in)。
