Notice Regarding Emissions

DANGER:This generator produces poisonous carbon monoxide gas when running. This

gas is both odorless and colorless. Even if you do not see or smell gas, carbon monoxide

may still be present. Breathing this poison can lead to headaches, dizziness, drowsiness,

and eventually death.

●Use outdoors ONLY in non-conned areas.

●Keep several feet of clearance on all sides to allow proper ventilation of the generator.

WARNING: The exhaust from this product contains chemicals known to the State of

California to cause cancer, birth defects, or other reproductive harm.

WARNING: This generator produces heat when running. Temperatures near exhaust can

exceed 150°F (65°C).

●Do not touch hot surfaces. Pay attention to warning labels on the generator denoting

hot parts of the machine.

●Allow generator to cool several minutes after use before touching engine or areas
