SAFETY INSTRUCTIONS
Carbon monoxide hazards
Exhaust contains poisonous carbon monoxide, a colorless, odorless gas. Breathing exhaust
can cause loss of consciousness and may lead to death. If you run the generator in an
area that is conned, or even partially enclosed area, the air you breathe could contain a
dangerous amount of exhaust gas.
Never run your generator inside a garage, house, or near open windows or doors.
Electric shock hazards
The generator produces enough electric power to cause a serious shock or electroc- ution 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 of the electrical
components on the control panel before each use. Moisture or ice can cause a malfunction
or short circuit in electrical components that could result in electrocution.
If you get an electric shock, consult a doctor and have medical treatment immediately.
Fire and Burn Hazards
Do not use the generator in areas with a high risk of re.
The exhaust system gets hot enough to ignite some materials.
-Keep the generator at least 1 meter (3 feet) away from buildings and other equipment
during operation.
-Do not enclose the generator in any structure.
-Keep ammable materials away from the generator.
Some parts of the internal combustion engine are hot and may cause burns. Pay attention
to the warnings on the generator.
The mufer becomes very hot during operation and remains hot for a while after stopping
the engine. Be careful not to touch the mufer while it is hot. Let the engine cool before
storing the generator indoors.

SAFETY INSTRUCTIONS
Do not pour the water directly on the generator to put out the re when it occurs.
Use an appropriate re extinguisher specially designed for electric re or oil re.
If you inhale fumes produced by an accidental re with the generator, consult adoctor and
have medical treatment immediately.
Refuel with care
Gasoline is extremely ammable, and gasoline vapor can explode. Allow the engine to cool
if the generator has been in operation.Refuel only outdoors in a well ventilated area with the
engine off. Do not refuel during operation.
Do not overll the fuel tank.
Never smoke near gasoline, and keep other ames and sparks away. Always store gasoline
in an approved container.
Make sure that any spilled fuel has been wiped up before starting the engine.

If you run the generator in an area that is conned,
Improper connections to a building's electrical system can allow
current from the generator to backfeed into the utility lines.
Such backfeed may electrocute utility company workers or others who
contact the lines during a power outage, and the generator may
explode, burn, or cause res when utility power is restored.
Consult the utility company or a qualied electrician prior to making
any power connections.
Gasoline is highly ammable and explosive. Turn the
engine off and let it cool before refueling.
Connect and remove the receptacle box for parallel
operation with the engine stopped. For single operation,
the receptacle box for parallel operation must be removed.
