5. Setup
5.1. Adding Engine Oil
The generator is shipped without engine oil. You must add the correct amount of oil before first use.
- Place the generator on a level surface.
- Locate and remove the oil fill cap/dipstick.
- Using the provided funnel, slowly add approximately 330 ml of 15W-40 engine oil. Do not overfill.
- Reinsert the dipstick and check the oil level. It should be at the upper mark.
- Securely replace the oil fill cap.
5.2. Adding Fuel
Use unleaded gasoline only. Do not use E85 or mixed fuels. Ensure the engine is off and cool before refueling.
- Unscrew the fuel cap.
- Carefully pour unleaded gasoline into the fuel tank. The tank capacity is 4 liters.
- Do not fill above the red indicator inside the tank. Leave space for fuel expansion.
- Securely replace the fuel cap.
6. Operating Instructions
6.1. Starting the Generator
- Ensure the generator is on a level surface and all electrical devices are disconnected.
- Turn the fuel valve to the 'ON' position.
- Move the choke lever to the 'CHOKE' position (for cold starts). For warm starts, the choke may not be necessary.
- Turn the engine switch to the 'ON' position.
- Firmly pull the recoil starter handle 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 electrical loads.
6.2. Stopping the Generator
- Disconnect all electrical loads from the generator.
- Allow the engine to run for a few minutes without load to cool down.
- Turn the engine switch to the 'OFF' position.
- Turn the fuel valve to the 'OFF' position.
6.3. Eco Mode
The Eco Mode switch allows the generator to automatically adjust engine speed to match the electrical load. This reduces fuel consumption and noise levels when less power is required.
- To activate Eco Mode, press the 'ECON SW' switch to the 'ON' position.
- To deactivate Eco Mode (for full power output), press the 'ECON SW' switch to the 'OFF' position.
6.4. Connecting Devices
Connect your devices to the appropriate outlets:
- AC 230V: Plug appliances directly into the 230V outlets. Ensure the total wattage does not exceed the generator's continuous output (1700W).
- USB Ports: Use standard USB cables to charge compatible devices.
- DC 12V: Use the provided 12V charging cables to connect to a 12V battery.
