• Electric Start: Includes battery and Quick Touch Panel for easy starting.
• Quiet Operation: Operates at 61 dBA from 23 feet, comparable to normal conversation.
• Clean Power: Produces electricity with less than 3% Total Harmonic Distortion (THD), safe for sensitive electronics.
• RV Ready: Features a 120V 30A RV (TT-30R) outlet, two 120V 20A household outlets (5-20R), and a 12V DC automotive-style outlet with dual USB adapter.
• Economy Mode: Reduces electrical load for quieter operation, extended engine life, and better fuel economy.
• Portability: Fully assembled with a foldaway handle, built-in handles, and never-flat tires for easy transport.
• Safety: Equipped with a low oil shut-off sensor.

3. Setup

Before operating your Champion 4500-Watt Inverter Generator, follow these essential setup steps:

1. Unboxing and Placement: Carefully remove the generator from its packaging. Place the generator on a firm, level surface outdoors, away from windows, doors, and vents to ensure proper ventilation and prevent carbon monoxide buildup.
2. Add Engine Oil: The generator requires 0.6 quarts of 10W-30 engine oil. Locate the oil fill cap/dipstick and use the included funnel to add the oil. Do not overfill. The low oil shut-off sensor will prevent the engine from starting if the oil level is too low.
3. Connect Battery: The electric start feature requires the battery to be connected. Locate the battery compartment, typically behind a side panel, and connect the battery terminals as instructed in the manual.
4. Fuel Selection: Decide whether to operate on gasoline or propane.
   • For Gasoline: Fill the fuel tank with unleaded gasoline (minimum 87 octane). Do not overfill.
   • For Propane: Connect the included propane hose with regulator to a 20-pound propane tank and to the generator's propane inlet. Ensure all connections are secure.

4. Operating Instructions

Follow these steps to safely operate your generator:

1. Starting the Generator:
   • Ensure the generator is on a level surface and all connections (fuel, battery) are secure.
   • Turn the EZ Start Dial to the appropriate fuel position (Gasoline or Propane).
   • Press the electric start button. If using the pull start, pull the recoil handle firmly.
   • Once the engine starts, allow it to run for a few moments before connecting any loads.
2. Connecting Electrical Loads:
   • Plug in your appliances or RV power cord into the appropriate outlets (120V 30A RV, 120V 20A household, or 12V DC/USB).
   • Avoid overloading the generator. Monitor the IntelliGauge display for wattage output.
3. Economy Mode:
   • Activate Economy Mode for quieter operation and improved fuel efficiency when running light loads.
   • The generator will automatically adjust engine speed to match the load.
4. Shutting Down:
   • Disconnect all electrical loads from the generator.
   • Allow the generator to run for a few minutes without load to cool down.
   • Turn the EZ Start Dial to the "OFF" position. If running on propane, close the valve on the propane tank first and let the engine run until it stalls to clear the fuel line.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your generator.

• Break-in Procedure: For new generators, it is recommended to run the unit for a break-in period (typically 5 hours) at varying loads, staying below 50% of the rated wattage. This helps seat the piston rings and allows the stator windings to heat and cool properly.
• Oil Changes: The generator has a 0.6-quart oil capacity. The first oil change should be performed after the break-in period. Subsequent oil changes are recommended every 50-100 hours of operation, depending on usage. Always use 10W-30 engine oil.
• Fuel Management:
  • If using gasoline, consider using a fuel stabilizer if storing the generator for extended periods to prevent fuel degradation and gumming issues.
  • Propane has a longer shelf life and is a cleaner-burning fuel, reducing carburetor maintenance.
• Air Filter: Regularly inspect and clean the air filter to ensure proper engine performance.
• Spark Plug: Check and clean or replace the spark plug as needed for reliable starting.

6. Troubleshooting

If your generator encounters issues, consider these common troubleshooting steps:

• Engine Not Starting:
  • Check fuel level (gasoline or propane).
  • Ensure the oil level is correct; the low oil shut-off sensor will prevent starting if too low.
  • Verify battery connections for electric start.
  • Check the spark plug for fouling or damage.
• No Power Output:
  • Check circuit breakers on the control panel; reset if tripped.
  • Ensure all electrical connections are secure.
  • Verify the generator is running at the correct RPM (Economy Mode might reduce RPM for light loads).
• Engine Running Rough:
  • Check fuel quality; stale gasoline can cause issues.
  • Inspect the air filter for clogs.
  • Ensure proper ventilation around the generator.
• Carbon Monoxide Warning: This generator is equipped with a CO Shield system. If the CO sensor detects high levels of carbon monoxide, the generator will automatically shut off. Move the generator to an open, well-ventilated area immediately.
