Every Predator generator sold by Harbor Freight is equipped with the CO Secure framework. This is indicated by a large warning light present on the generator’s control panel. As the generator works, its internal CO sensor is constantly monitoring the CO levels in its immediate vicinity. If the ambient CO levels cross a threshold of danger to living beings, the generator will shut itself off automatically and begin flashing its warning light red for five minutes.
When the light is flashing, the levels of CO around the generator are not safe to stand in, which means you need to stay clear until the area has aired out. Once the light shuts off, you need to move the generator from its current position to a more well-ventilated one before you start it back up again, one with at least 5 feet of clearance on all sides of the generator.
Once you start the generator again, the light should shut off if the ambient CO levels are safe. If they aren’t, the generator will swiftly shut itself off again. In addition to the red light, if the generator experiences some kind of problem with its CO detection system, it will begin flashing a yellow light, which means you’ll need to schedule service right away.
