2. Safety Information
WARNING: Failure to follow these safety instructions can result in serious injury or death.
- Carbon Monoxide Hazard: Generators produce carbon monoxide, an odorless, colorless, poisonous gas. Operate generators outdoors only, far away from windows, doors, and vents. Never operate indoors, in garages, or in partially enclosed areas.
- Fire Hazard: Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the generator. Store fuel in approved containers away from living areas.
- Electrical Shock Hazard: Never operate the generator in wet conditions. Ensure all electrical connections are secure and dry. Do not connect the generator directly to your home's electrical system without a transfer switch installed by a qualified electrician. This can cause backfeeding, which is dangerous for utility workers.
- Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid contact to prevent burns.
- Moving Parts: Keep hands, feet, hair, and clothing away from moving parts to prevent injury.
- Children and Pets: Keep children and pets away from the generator at all times.
