Yes
(Main Reservoir Pipe is train-lined)
When do both Air Compressors operate simultaneously?
Main Reservoir Pressure falls below 650kpa
What fault light illuminates when Main Reservoir Pressure drops below 650kpa?
Low Pressure in Main Reservoir Fault Light
What should a driver do when Main Reservoir Pressure is between 750kpa and 580kpa?
- Book TMM
- Continue as normal (monitor MR pressure)
If the Air Compressors aren’t running, what should the driver do?
