ETR and ETS refer to how the shutoff solenoid is operated on older mechanical engines.
ETR is Energize To Run
ETS is Energize To Shutdown. This used a timer, when the engine needed to be shutdown the solenoid was energized for 70 seconds.
I don't have this manual in electronic format (still have a paper copy)
Maybe another member can help with a manual
