Carbon Monoxide Hazards
• Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing exhaust can cause loss of consciousness and may
lead
to death.
$ If you run the generator in an area that is confined, or even partially enclosed, the air you breathe could contain a dangerous amounts of
exhaust gas.
To keep exhaust gas from building up, provide adequate ventilation.
Electric Shock Hazards
• The generator produces enough electric power to cause a serious shock or electrocution if misused.
• Using a generator or electrical appliance in wet conditions, such as rain or snow, or near a pool or sprinkler system, or when your hands are
wet, could result
in electrocution. Keep the generator dry.
• If the generator is stored outdoors, unprotected from the weather, check all electrical components on the control panel, before each use.Moisture
or ice can cause a malfunction or short circuit

-Keep flammable materials away from the generator.
• The muffler becomes very hot during operation and remains hot for a while after stopping the engine. Be careful not to touch the muffler while
it is hot. Let the engine cool before storing the generator indoors.
• Gasoline is extremely flammable and is explosive under certain conditions. Do not smoke or allow flames or sparks where the generator is
refueled or where gasoline is stored. Refuel in a well-ventilated area with the engine stopped.
