Carbon Monoxide (CO) Detection and Shut-off System
This generator features CO WARNING, which will automatically shut-off if dangerous levels of CO is
detected.
Carbon monoxide (also known as CO) can be dangerous for humans and pets. Carbon monoxide
poisoning can lead to death in a very short time. It is called "the silent killer" because it is odorless,
tasteless and invisible: you may be exposed without knowing it.
The CO Detection module monitors for the accumulation of poisonous CO gas found in engine exhaust
when the generator is running. If CO detector detects increasing levels of CO gas, it automatically
shuts off the engine. CO detector only monitors when the engine is running. Generators are intended to
be used outdoors, far from occupied buildings and the exhaust pointed away from personnel and
buildings. However, if misused and operated in a location that results in the accumulation of CO, like
indoors or in a partially enclosed area, CO detector shuts off the engine, notifies the user of what has
happened and directs the user to read the instruction action label for steps to take. CO detector is not
a substitute for an indoor carbon monoxide alarm.
After a shut-off, a blinking RED light in the CO detector badge on the side of the generator provides
notification that the generator was shut off due to an accumulating CO hazard. The RED light will blink
for at least five minutes after a CO shut-off. Move the generator to an open, outdoor area and point the
exhaust away from people and occupied buildings. Once relocated to a safe area, the generator can be
restarted and the proper electrical connections made to supply electrical power. The RED light will stop
blinking automatically upon engine re-start. Introduce fresh air and ventilate the location where the
generator had shut down.
If a CO detector system fault has occurred and no longer provides protection, the portable generator is
shut off automatically and the YELLOW light will blink for at least five minutes in the CO detector badge
to notify the user of the fault. The CO detector module can only be diagnosed and repaired by a trained
technician at the dealer. The generator can be re-started, but may continue to shut-off.
CO detector will detect the accumulation of Carbon Monoxide from other fuel burning sources such as
engine powered tools or propane heaters used in the area of operation. For example, if another
generator is used and the exhaust is pointed at a CO detector equipped generator, CO detector may
initiate a shut-off due to rising CO levels. This is not an error. Hazardous Carbon Monoxide has been
detected. The user must take action to move and re-direct these devices to better dissipate Carbon
Monoxide far away from personnel and occupied buildings.
