- 起动发动机。 储脂罐内的浆片应当顺时针转动。
- 记下泵的运行时间。 确保运行时间与计时器参数一致。 关于润滑泵的时间间隔，请参阅系统操作, "电气系统"内的表 1。
- 通过按泵底座上的手动按钮反复循环运行系统。
- 润滑剂流经主润滑分配阀 (2) 。 润滑剂流驱动指示杆 (3) ，为正常工作的确认提供直观指示。 润滑剂泵运行中，指示杆 (3) 应当内外移动。
- 润滑剂流经辅助润滑分配阀 (5) 。 润滑剂流驱动指示杆（未显示），为正常工作的确认提供直观指示。
- 断开某轴承上的一条润滑管。
- 继续手动循环润滑泵 4 分钟。
- 关闭发动机。
- 润滑剂应当从断开的润滑管中喷出。 重新连接润滑管。
