Please carefully read the extremely important safety warnings we have written in the User Manual and the sticker of the generator set. This is to remind you of the potential dangers which may harm you and others. Before each safety warning is a symbol and one of the three following words: danger, warning or caution. These words indicate: If you fail to follow the instructions, your life will be at risk or you will be severely injured. If you fail to follow the instructions, your life may be at risk or you may be seriously injured. If you fail to follow the instructions, your generator set and other property may be damaged. General Safety Guidelines • Carbon Monoxide Hazards 1. Exhaust gas from the generator contains toxic carbon monoxide fumes. Inhaling these fumes may lead to shock, loss of consciousness or even death 2. Do not use the generator indoors, including in homes, garages, basements, and other enclosed or partially- enclosed areas. 3. Keep the generator away from doors, windows, and vents to prevent CO from entering indoors. 4. Leave at least three feet of space on all sides of the generator to ensure adequate ventilation. | 2 5. Install battery-powered carbon monoxide alarms in your home to alert for CO level. • Electrical Hazards 6. Do not use the generator in damp environments. 7. Do not operate the generator with a damaged cord or plug. 8. Do not overload the generator. Ensure the connected loads do not exceed its wattage capacity to prevent damage. 9. Earthing the Generator: The generator is equipped with a grounding system that connects its frame components to the ground terminal in the AC outlet. Before use, always ensure the grounding terminal is connected to appropriate grounding equipment, such as a grounding rod. Grounding codes can vary by location. Check with your local electrical regulation for specific requirements. 10. Floating Neutral: The grounding system does not connect to the AC neutral line. 11. Electrical Backfeeding Hazards: Do not connect the generator to a building’s electrical system unless a licensed electrician has installed an isolation switch. Check with your local electrical regulation for specific requirements. • Fire Hazards 12. Keep any combustibles at least 1m / 3ft away. The generator’s components or exhaust system can become very hot during operation. 13. Keep fuel away from sparks, open flames, and any other ignition sources. • Environment Requirements 14. Follow the environment temperature requirements specified in the product specification to use or store the generator. Avoid degradation or damage to the generator, or risks to personal safety due to excessively high or low temperatures. 15. Usage in High Altitude Areas: In high altitude areas, the atmospheric pressure may reduce the amount of air intake, decline the performance and increase the fuel consumption of standard carburetors. Moreover, the dense mixture may contaminate the spark plug and lead to…
