2. Important Safety Information

Always read and understand this entire manual before operating the generator. Failure to follow instructions can result in serious injury or death. Generators produce carbon monoxide (CO), an odorless, colorless gas that can kill you. Always operate the generator outdoors in a well-ventilated area, far away from windows, doors, and vents. Never operate it inside a home, garage, shed, or other enclosed space.

• Carbon Monoxide (CO) Hazard: This generator is equipped with a CO sensor that automatically shuts down the engine if CO levels become too high. Do not disable or bypass this safety feature.
• Fire Hazard: Fuel is highly flammable. Always refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the generator.
• Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all electrical connections are secure and properly grounded.
• Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid contact with hot surfaces.

5. Initial Setup

Before first use, or after extended storage, follow these steps to prepare your generator:

1. Add Engine Oil: The generator is shipped without engine oil. Unscrew two screws on the side panel, pop the side panel, and use the included filler tube and funnel to add the appropriate 4-stroke engine oil. Refer to the specifications section for oil type and capacity. Note: All Efurden generators are factory tested, so a slight smell of gas may be present upon receipt. It is recommended to change the oil after the first tank of fuel.
2. Add Fuel: Fill the 1.1-gallon fuel tank with fresh, unleaded gasoline. Ensure the fuel cap is securely tightened but allow for venting during operation if applicable.
3. Check Connections: Ensure all electrical connections are secure and the generator is placed on a firm, level surface outdoors, away from any combustible materials.

6. Operating Your Generator

Starting the Generator:

1. Ensure the generator is on a level surface and all connections are secure.
2. Turn the fuel valve to the ON position.
3. Set the engine switch to the CHOKE position (if cold starting).
4. Pull the recoil starter handle firmly and smoothly until the engine starts.
5. Once the engine starts, gradually move the engine switch to the RUN position.

ECO Mode:

The ECO mode switch allows the generator to automatically adjust engine speed to match the load, saving fuel and reducing noise. When you don't need full power, turn the ECO switch to the ON position. This will decrease power and fuel consumption, and significantly reduce the noise level.

Parallel Operation:

For increased power output, two Efurden 2500-Watt Inverter Generators can be connected in parallel using a compatible parallel kit (sold separately). This allows you to double the available wattage without sacrificing portability.

CO Sensor Protection:

The integrated CO sensor continuously monitors carbon monoxide levels. If unsafe levels are detected, the generator will automatically shut down to protect users. Ensure the generator is always operated in an open, outdoor environment to prevent CO buildup.

7. Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your Efurden generator. Always ensure the engine is off and cool before performing any maintenance.

• Oil Change: Check engine oil level before each use. Change the oil after the first 20 hours of operation, and then every 50-100 hours or annually, whichever comes first.
• Air Filter: Inspect the air filter regularly and clean or replace it as needed, especially in dusty conditions.
• Spark Plug: Inspect the spark plug annually or every 100 hours. Clean or replace if necessary.
• Fuel Filter: Check and clean the fuel filter periodically.
• General Cleaning: Keep the generator clean and free of debris. Use a damp cloth to wipe down exterior surfaces.
