Starting Air Pressure - Adjust
必须检查每台发动机的安装，以确定最有利的起动条件。 气压调节阀的设定受到下述因素的影响：
- 来自起动期间发动机拖动的附加装置的负载
- 环境温度条件
- 空气起动马达润滑剂的粘度
- 储气罐的容量
- 发动机状况
较高的气压增加起动马达的扭矩和使发动机更快地旋转。 较低的气压延长压缩空气的供气时间。
注: 确保供气管具有适当的尺寸。 如未能提供足够量的空气到起动机，则将会导致起动机旋转减慢和起动扭矩降低。
使用下述步骤来检查和调整气压调节阀：
- 将压缩空气从系统中排出。
- 断开调节器出气口 (3) 的气管。

- 将 8T-0849 压力表 连接到调节器出气口 (3) 。
- 向压力表施加气压，并检查气压。
- 使用调整螺钉 (1) 将气压调整到 620 至 1030 kPa (90 至 150 psi)。
- 正确调整气压之后，将系统的压缩空气排出。
- 从调节器出气口拆下 8T-0849 压力表总成 。 接回气管。
