“Tonight, when we want to shut the generator down, how do I do that?”

You will hit the circuit breaker switch on the generator first. Let the unit run for about 10 minutes to cool down, then turn to the “OFF” position. In the morning, you will turn the unit to “AUTO” and it will go on if you have no power, let it warm up for a few minutes, then turn the circuit breaker switch on the unit back on.
