Carbon monoxide detectors. Carbon monoxide can
cause severe nausea, fainting, or death. Install carbon
monoxide detectors on each level of the building. Locate the
detectors to adequately warn the building's occupants of the
presence of carbon monoxide. Keep the detectors operational
at all times. Periodically test and replace the carbon monoxide
detectors according to the manufacturer's instructions.

WARNING
Hot coolant and steam.
Can cause severe injury or death.
Before removing the pressure cap,
stop the generator set and allow it to
cool. Then loosen the pressure cap
to relieve pressure.
Allow the engine to cool. Release pressure from the
cooling system before removing the pressure cap. To
release pressure, cover the pressure cap with a thick
cloth and then slowly turn the cap counterclockwise to
the first stop. Remove the cap after pressure has been
completely released and the engine has cooled. Check
the coolant level at the tank if the generator set has a
coolant recovery tank.
