Adding Engine Oil
The generator is shipped without engine oil. Before first use, add the recommended amount and type of oil (typically 10W-30) using the provided oil funnel. Refer to the owner's manual for exact oil capacity and type. The generator is equipped with a low oil alert light and automatic shutdown to protect the engine.
Adding Fuel
This generator operates on gasoline. Fill the fuel tank with fresh, unleaded gasoline. Do not overfill. Ensure the fuel cap is securely tightened after refueling.
Warning: Do not use E85 or any other fuel containing more than 10% ethanol. This can damage the engine and void the warranty.

Parallel Capability
The SUA4000i is designed with fully integrated parallel capability, allowing you to connect two identical generators together to double the power output. Refer to the owner's manual for detailed instructions on parallel connection using the appropriate cables.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your generator. Always shut down the engine and allow it to cool before performing any maintenance.
- Engine Oil: Check oil level before each use. Change engine oil after the first 20 hours of operation, then every 100 hours or annually, whichever comes first.
- Air Filter: Inspect and clean the air filter every 50 hours or more frequently in dusty conditions. Replace if damaged.
- Spark Plug: Inspect the spark plug every 100 hours. Clean or replace as needed.
- Fuel Filter: Inspect and clean or replace the fuel filter as recommended in the owner's manual.
- Storage: For long-term storage, drain the fuel tank and carburetor, or add a fuel stabilizer. Store in a clean, dry area.
