- 将工具 (C) 安装在工具 (D) 上，连接工具 (E) 和气罐，以及测试压力表。
- 起动发动机，使气压增加到最大压力。
- 参考连到左侧气罐测试压力表的截断压力。
- 多次上下踩动行车制动器（踏板），把其交替合上和松开。 动作要快。
- 参考测试压力表的接通压力。
- 正确的接入压力为 790 ± 70 kPa (115 ± 10 psi)。 正确的截断压力为 965 ± 34 kPa (140 ± 5 psi)。
必要时，对空气压缩机调节器作以下调整:
- 把空气压缩机调节器 (7) 的顶盖 (8) 打开。

- 松开调节螺钉的锁定螺母。
- 把调节螺钉反时针方向拧转，使接通压力提高。
- 把调节螺钉顺时针方向拧转，使截断压力降低。

注: 空气压缩机的排列取决于发动机的配置。
- 如果调节螺钉不能使截断压力改变，则空气压缩机的卸载阀工作失常。
- 如果接通压力和截断压力的差别不正确，则空气压缩机调节器工作失常。
