- Pull Start: Firmly pull the recoil start handle until the engine starts.
- Run Position: Once the engine starts, turn the EZ Start Dial to the 'Run' position.
Connecting Equipment:
The generator offers multiple outlets for various power needs:
- 120V 20A Household Duplex Outlet (5-20R): For standard household appliances and tools.
- 12V Automotive-Style Outlet: For charging 12V batteries or powering compatible devices.
- Dual Port USB Adapter: For charging mobile devices and other USB-powered electronics.
Plug in your desired equipment into the appropriate outlets. The generator provides clean power, safe for sensitive electronics.

Economy Mode:
Activate Economy Mode to optimize fuel consumption and reduce noise. When the electrical load is reduced, the inverter automatically lowers engine speed, leading to quieter operation, extended engine life, and higher fuel economy.
CO Shield® Safety System:
The integrated CO Shield® technology continuously monitors carbon monoxide (CO) levels. If unsafe elevated levels of CO gas are detected, the system will automatically shut off the engine to prevent carbon monoxide poisoning. This is a critical safety feature, but generators must ALWAYS be used outdoors, far away from occupied buildings.

Parallel Operation (Optional):
For increased power output, you can connect this inverter with another 2800-watt or higher Champion inverter using an optional Parallel Kit (sold separately). This allows you to combine the power of two units for greater versatility.
