Its vapor is explosive. · Keep fuel out of children’s reach. · Refuel generator in a well-vented area. Do not fill fuel tank in the dark. Do not refuel while engine is running. Unhook all electrical loads and shut off engine before refueling. · Do not overfill fuel tank. Always allow room for fuel to expand. If you overfill tank, fuel can overflow onto hot generator. This can cause fire or explosion. After refueling, tightly close fuel tank cap. · Do not spill fuel. Fuel or fuel vapor may ignite. If fuel spills, make sure area is dry before starting engine. · Never smoke in refueling area. Never allow open flames or sparks in area. · Store fuel in approved container. Store fuel in a well-vented area free of open flames or sparks. Guard against fire hazard. Keep operation area well-vented. Keep generator at least three feet away from any object. Do not place flammable objects near generator. · Do not use generator where flammable vapors are present. Some vapors are heavier than air. These vapors settle in low-lying places. · Do not use generator in enclosed spaces. This includes motor home or RV generator compartments. Guard against electric shock. Generator produces high voltage. This high voltage can cause severe electric shock. Only responsible adults should use generator. · Properly ground generator before starting. · Never let anyone operate or service generator without proper instructions. · Avoid contact with live terminals or bare wires. · Do not use generator outdoors in rain or snow. · Do not use generator near standing water or snow. · Do not use if generator is wet or damp. · Do not use generator in highly conductive areas. These areas include metal decking and steelwork. · Only use grounded extension cords. 2 4. 5. 2. 6. 3. 7. 8. · Do not use any worn or damaged electric cords. Electric shock or damage to generator may result. · Do not wear damp clothing or wet shoes when using generator. Guard against burns. Hot engine parts can cause severe injury. Use caution and remain alert when using generator. · Keep children and animals away from generator while it is running or hot. · Keep all covers and shields in place. Keep them tightly secured. · The muffler becomes very hot during operation. The muffler remains hot for a while after shutdown. Do not touch muffler while it is hot. Do not let muffler touch anything flammable. Let engine cool before transporting or storing. Have standby installation to home or building performed by a licensed electrician. Do not let anyone else wire into a utility circuit. Personal injury, equipment damage, or damage to home could occur. Never connect generator to any existing electrical circuits. The generator output will back-feed into the utility power line. This may electrocute a power company line repair person. Also, if generator is powering electrical circuits, the chance of an electrical fire exists. Battery gives off explosive gases. Keep sparks, flames, and cigarettes away. Do not remove or install battery cables when engine is cranking or running. Only service or use battery in a wellvented area. Battery contains sulfuric acid. Battery acid is poisonous if swallowed.
