• 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 heat sources.
• Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all electrical connections are secure and dry. Use only grounded extension cords and appliances.
• Hot Surfaces: The generator engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid contact to prevent burns.
• Children and Pets: Keep children and pets away from the generator during operation and while it is cooling down.
