1. Safety Instructions
Always read and understand all safety warnings and instructions before operating the generator. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
General Safety Guidelines
- Carbon Monoxide Hazard: Never operate the generator indoors or in poorly ventilated areas. Exhaust contains carbon monoxide, a colorless, odorless, poisonous gas that can kill you.
- Fire Hazard: Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow flames or sparks near the generator.
- Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all electrical connections are secure and properly grounded. Never touch live electrical parts.
- Moving Parts: Keep hands, feet, hair, and clothing away from moving parts to prevent injury.
- Children and Pets: Keep children and pets away from the generator, especially when it is operating.
- Proper Grounding: Always ensure the generator is properly grounded before use to prevent electric shock.

3. Setup and Assembly
3.1 Unpacking and Inspection
Carefully remove the generator from its packaging. Inspect for any damage that may have occurred during shipping. Report any damage to your dealer immediately. Ensure all components listed in the packing list are present.
3.2 Wheel and Handle Assembly
The transport wheels and foldable handles need to be assembled. Use the provided hardware and tools (or your own if better suited) to securely attach them. Refer to the assembly diagrams in the separate assembly guide if provided.
3.3 Adding Engine Oil
The generator is shipped without engine oil. Before first use, you must add the correct type and amount of oil. Locate the oil fill cap/dipstick. Fill with approximately 1.1 liters of SAE 10W-30 or 10W-40 engine oil (check manual for exact specification and capacity). Do not overfill. The oil alert lamp will prevent the engine from starting if the oil level is too low.
3.4 Adding Fuel
Use only fresh, unleaded gasoline with an octane rating of 87 or higher. The fuel tank capacity is 25 liters. Fill the tank slowly to avoid spills, leaving a small air gap at the top. Do not overfill. Ensure the fuel cap is securely tightened after refueling.
4. Operating Instructions
4.1 Starting the Generator
Before starting, ensure the generator is on a level surface, away from combustible materials, and in a well-ventilated area.
- Ensure the circuit breakers are in the 'OFF' position.
- Turn the fuel valve to the 'ON' position.
- If the engine is cold, move the choke lever to the 'CHOKE' position.
- Electric Start: Insert the key into the ignition switch and turn it to the 'START' position. Release the key once the engine starts.
- Recoil Start: Pull the recoil starter handle slowly until resistance is felt, then pull quickly and firmly. Repeat if necessary until the engine starts.
- Once the engine starts, slowly move the choke lever to the 'RUN' position. Allow the engine to warm up for a few minutes before connecting any loads.
4.2 Connecting Electrical Devices
Once the generator is running smoothly, you can connect your electrical devices. Ensure the total wattage of connected devices does not exceed the generator's rated output.
- For 230V devices, plug them into the 230V AC outlets.
- For 400V devices, plug them into the 400V AC outlet.
- For 12V DC devices, use the 12V DC connector. This is typically used for battery charging.
- Flip the circuit breakers to the 'ON' position to supply power to the outlets.
4.3 Shutting Down
- Disconnect all electrical loads from the generator.
- Turn the circuit breakers to the 'OFF' position.
- Turn the engine switch to the 'OFF' position.
- Turn the fuel valve to the 'OFF' position to prevent fuel flow to the carburetor.
5. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your generator. Always perform maintenance with the engine off and cool, and disconnect the spark plug cap to prevent accidental starting.
Regular Maintenance Schedule:
- Before Each Use: Check engine oil level, check fuel level, inspect for any visible damage or leaks.
- Every 25 Hours or Annually (whichever comes first): Change engine oil.
- Every 50 Hours or Annually: Clean/inspect air filter, inspect spark plug.
- Every 100 Hours or Annually: Replace spark plug, inspect fuel filter (replace if necessary), inspect fuel lines.
- Storage: For long-term storage, drain the fuel tank and carburetor, or use a fuel stabilizer. Store in a dry, well-ventilated area.
