2. Important Safety Information

Always follow these safety guidelines to prevent serious injury or death.

• Carbon Monoxide Hazard: Generators produce carbon monoxide (CO), a colorless, odorless, poisonous gas. Operate the generator ONLY outdoors and far away from windows, doors, and vents. Never operate indoors, in a garage, or in any enclosed space.
• Fire Hazard: Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cooled. Do not smoke or allow open flames near the generator.
• Electrical Shock Hazard: Never operate the generator in wet conditions. Ensure all electrical connections are dry 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 touching hot surfaces to prevent burns.
• Children and Pets: Keep children and pets away from the generator, especially during operation.
• Read the Manual: Always read and understand the entire instruction manual before operating the generator.

4. Initial Setup

Before starting your generator for the first time, perform the following steps:

4.1 Add Engine Oil

1. Remove the maintenance cover by loosening the screws.
2. Unscrew and remove the oil dipstick.
3. Using the provided oil funnel, add 350ml of new SAE 10W-30 engine oil. Do NOT overfill; the oil level should not exceed the "H" position on the dipstick.
4. Tighten the oil dipstick securely.
5. Reinstall the maintenance cover.

4.2 Add Gasoline

1. Remove the fuel cap.
2. Add E10 gasoline. The gasoline level should NOT be higher than the red ring inside the fuel tank. The fuel tank capacity is 1.1 gallons.
3. Carefully tighten the fuel tank cap.

5. Operating Instructions

5.1 Starting the Generator (Recoil Start)

1. Turn the three-in-one switch to the "CHOKE" position.
2. Ensure the ECO switch is in the "OFF" position.
3. Firmly grasp and pull the recoil handle slowly until you feel increased resistance, then pull rapidly.
4. Once the engine starts and runs smoothly, turn the engine switch to the "RUN" position.
5. After the AC indicator turns green, plug in your device.

5.2 Stopping the Generator

1. Remove all loads from the output receptacles.
2. Turn the three-in-one switch to the "OFF" position.
3. NOTICE: Always turn off the main power switch on the control panel after use. A drained battery will prevent the generator from starting.

6. Maintenance

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

6.1 Clean the Air Filter

1. Take off the air filter cover.
2. Take out the sponge air filter element.
3. Wash the filter element in household detergent and warm water.
4. Use a clean cloth to slowly squeeze out excess water, then air dry naturally.
5. Spray some engine oil on the filter element. Use a clean absorbent cloth to squeeze out excess oil.
6. Place the air filter element in the assembly and install the air cleaner cover.

6.2 Drain the Gasoline for Storage

If storing the generator for an extended period, drain the gasoline to prevent fuel degradation issues.

1. Turn the three-in-one switch to the "RUN" position.
2. Loosen the drain bolt counterclockwise on the carburetor.
3. Allow gasoline to drain into a suitable container.
4. After discharging gasoline, tighten the drain bolt clockwise.
5. Install the maintenance cover.

6.3 Replace the Spark Plug

1. Remove the spark plug maintenance cover.
2. Pull off the spark plug cap.
3. Turn the spark plug wrench counterclockwise to remove the old spark plug.
4. Install the new spark plug clockwise using the wrench.
5. Fasten the spark plug maintenance cover.

7. Troubleshooting

If your generator encounters issues, refer to the following common troubleshooting steps. For complex problems, contact customer service.

7.1 Generator Cannot Recoil Start (First Use)

1. Check Oil Level: Ensure the oil level is correct and not overfilled. If the low oil indicator light is still yellow after filling, disconnect the oil sensor connector (this will disable the low oil warning function).
2. Check Fuel System: Verify that the entire fuel system is unobstructed. Turn the fuel switch to the "ON" or "RUN" position. Locate the carburetor and loosen the drain bolt counterclockwise to allow gasoline to drain. If gasoline flows continuously, the system is fine. If it flows intermittently or very little, the fuel system is obstructed. Check if the fuel pipe is folded or bent and correct it.
3. Check Circuit System: Remove the spark plug maintenance cover and check if the spark plug cap is inserted properly. Take out the spark plug and check for damage; replace if necessary. Check if the spark plug ignites when starting the generator (hold the spark plug against the engine case, but do not touch with bare hands due to electric shock risk). If there is no spark, check for loose or damaged plug boxes.
4. Check Carburetor Choke Operation: (Applicable to recoil start models only) Locate the throttle stepper motor above the carburetor. Turn the three-in-one switch to the "RUN" position. Loosen the fixing bolts on the carburetor and let the throttle assembly automatically return to the fully open position. Pull the cable to ensure the choke cable is straight, then tighten the cable fixing bolts. Turn the three-in-one switch to the choke position and observe whether the choke position is correct.

If the above checks cannot solve your problem, please contact our customer service.
