Operating Instructions
Control Panel Overview
The generator's control panel provides all necessary controls and indicators. It features a digital display for remaining run time, fuel level, power output, and voltage. It also includes two 120V AC outlets, two USB ports (1.0A and 2.1A), and a 12V DC outlet.

Starting the Generator
To start the generator, ensure the eco mode switch is in the 'Off' position. Turn the fuel valve to the 'On' position. The generator can be started using the pull cord or, if equipped, via remote control. Allow the engine to warm up for a few minutes before connecting loads.
Eco Mode
The Eco Mode feature automatically adjusts the engine speed to match the electrical load. This optimizes fuel consumption and reduces operational noise when full power is not required. Switch to 'On' for Eco Mode operation.

Maintenance
Regular maintenance is crucial for the longevity and performance of your generator. Always refer to the detailed maintenance schedule in your user manual for specific intervals and procedures.
- Oil Change: Perform after the first 20 hours of operation, then every 50-100 hours or annually, whichever comes first.
- Air Filter: Inspect regularly and clean or replace as needed, especially in dusty conditions.
- Spark Plug: Inspect and clean or replace annually to ensure reliable starting and efficient operation.
- Fuel System: Use fuel stabilizer for storage. If storing for extended periods, drain the fuel tank and carburetor to prevent fuel degradation.
Troubleshooting
This section addresses common issues you might encounter with your generator. For more complex problems, consult the full user manual or contact customer support.
- Generator won't start: Check fuel level, oil level, spark plug condition, and ensure the engine switch is in the 'On' position.
- No power output: Check the AC circuit breakers on the control panel. Ensure the generator is not overloaded (overload indicator will be red). Verify the output ready indicator is green.
- Overload indicator on: Reduce the connected load. The generator will automatically shut down if overloaded to prevent damage.
- Low oil indicator on: The generator will shut down or not start if the oil level is too low. Add engine oil to the recommended level.
