CO DETECT technology monitors the accumulation of carbon monoxide (CO), a poisonous gas produced by
engine exhaust when the generator is running. If CO Sensor detects unsafe elevated levels of CO gas, it
automatically shuts off the engine. CO Sensor is not a substitute for an indoor carbon monoxide alarm or for safe
operation. DO NOT allow engine exhaust fumes to enter a confined area through windows, doors, vents or other
openings. Generators must ALWAYS be used outdoors, far away from occupied buildings with engine exhaust
pointed away from people and buildings. Meets the requirements of ANSI/PGMA G300-2018.
