1. SAFETY
DANGER!
Using a generator indoors can kill you in minutes.
Generator exhaust contains carbon monoxide. This is a poison
that you cannot see or smell.
NEVER use inside a home or garage.
WARNING!
This product can expose you to chemicals including carbon
monoxide, which is known to the State of California to cause
cancer and birth defects or other reproductive harm. For more

1.1 OPERATOR SAFETY
WARNING!
Always perform an oil, fuel and air lter check before starting the engine.
Properly clean and maintain the equipment.

dependable service.
Before operating the generator, read the user guide carefully. Otherwise,
personal injuries or equipment damage may result.
Never run the generator in an enclosed area to avoid harm from exhaust
emissions of a poisonous carbon monoxide gas.
Pay attention to the warning labels. The engine exhaust system will
become heated during operation and remain hot immediately after the
engine is stopped.
TOXIC FUMES HAZARD. Running engines give off
carbon monoxide, an odourless poisonous gas
that can cause nausea, fainting, or death. Do
not start engine indoors or in an enclosed area,
even if the windows and doors are open.
DANGER TOXIQUE. Faire fonctionner un moteur dégage de
l’oxyde de carbone, un gaz inodore toxique qui peut
provoquer la nausée, évanouissement ou la mort. Ne
démarrer pas le moteur à l’intérieur ou dans une espace clos,
meme si les fenêtres et les portes sont ouvertes.

Gasoline is a highly ammable and explosive liquid. Refuel in a well
ventilated area with the engine stopped.
When refueling the generator, keep it away from cigarettes, open ames,
smoke and/or sparks.
Use of gasoline with an ethanol content greater than 10% can damage
the engine and fuel system and will void the manufacturer’s warranty.
Place the generator at least 10 feet away from buildings or other
equipment during operation.
Run the generator on a level surface. Tilting the generator may result in
fuel spills.
Do not touch the spark plug while the engine is operating or shortly after
the engine has been shut down.
Know how to stop the generator quickly and understand operation of
all the controls. Never permit anyone to operate the generator without
proper instructions.
Keep children, pets and machinery with rotating parts away during
operation.
Do not operate the generator in rain or snow.
Do not allow any moisture to come in contact with the generator.
1.2 AC SAFETY
WARNING!
Before connecting the generator to an electrical device or power cord:
Make sure that everything is in proper working order. Faulty devices or
power cords can lead to an electrical shock.
Turn off the generator immediately if the device begins to operate
abnormally. Then disconnect the device and investigate the problem.
Keep away from other electric cables or wires.
To prolong engine life, make sure that the combined load of your
devices does not exceed the rated running wattage of the generator.
When an extension cable is required, be sure to use a tough rubber
sheathed exible cable (according to IEC245 or equivalent standards).
The maximum length of the extension cable: 196 feet (60 meters) for
cable of 15.5 gauge (1.5mm2); 328 feet (100 meters) for cable of 13.25
gauge (2.5mm2).
Connections for standby power to a building’s electrical system must
be done by a qualied electrician and must comply with all applicable
