Yes, you must have air for the air solenoid to pull back on the throttle box ( I will call it). I have seen a few coaches with a metal handle, like a “T” on the drivers side, rear compartment door next the the radiator. It is a manual shutoff. Just a mechanical rod connected to the throttle box to pull back the rack to stop the engine
