Operating a generator can be hazardous if proper safety precautions are not followed. Always prioritize safety to prevent serious injury or death. This section outlines critical safety guidelines. Refer to the complete owner's manual for a comprehensive list of safety instructions.
2.1 Carbon Monoxide Hazard
- Generators produce carbon monoxide (CO), an odorless, colorless, and poisonous gas.
- NEVER operate the generator indoors, in a garage, or in any enclosed or partially enclosed area.
- Always operate the generator outdoors in a well-ventilated area, far away from windows, doors, and vents.
- Install battery-operated carbon monoxide alarms in your home or RV.
2.2 Electrical Safety
- Do not operate the generator in wet conditions, such as rain or snow.
- Ensure all electrical connections are secure and properly grounded.
- Use only approved extension cords that are rated for outdoor use and the appropriate amperage.
- If connecting to a home's electrical system, use a transfer switch installed by a qualified electrician to prevent backfeeding into the utility grid.
2.3 Fuel Safety
- Gasoline and propane are highly flammable. Handle with extreme care.
- Refuel gasoline only when the engine is off and cool.
- Store fuel in approved containers in a well-ventilated area, away from ignition sources.
- Do not smoke near the generator or fuel.

5. Operating Instructions
Follow these steps to safely start and operate your generator.
5.1 Pre-Start Checks
- Ensure the generator is on a level surface outdoors, away from combustible materials.
