5. Setup
Before starting your generator for the first time, follow these steps carefully:
- Unpacking: Carefully remove the generator from its packaging. Inspect for any shipping damage.
- Add Engine Oil: The generator is shipped without engine oil. Locate the oil fill cap/dipstick. Add the recommended type and amount of engine oil (refer to specifications for oil type and capacity). Do not overfill.
- Add Fuel: Ensure the generator is turned off and cool. Open the fuel cap and fill the fuel tank with fresh, unleaded gasoline. Do not overfill. Leave some space for fuel expansion.
- Check Connections: Ensure all electrical connections are secure and free from damage.
- Grounding: For safety, ensure the generator is properly grounded. Connect a grounding wire from the generator's grounding terminal to an appropriate ground source.
6. Operating Instructions
Starting the Generator:
- Place the generator on a flat, level surface outdoors, away from any enclosed areas.
- Ensure the fuel valve is in the 'ON' position.
- Move the 3-in-1 switch to the 'CHOKE' position (if the engine is cold).
- Pull the recoil starter handle firmly and smoothly until the engine starts.
- Once the engine starts, slowly move the 3-in-1 switch to the 'RUN' position.
- Allow the generator to warm up for a few minutes before connecting any electrical devices.
Connecting Appliances:
- Ensure the generator is running stably.
- Plug your appliances into the appropriate AC or DC outlets.
- Do not exceed the generator's rated running wattage (2800W) or starting wattage (3100W). Overloading can trip the circuit breaker or damage the generator/appliances.
Using ECO Mode:
- The ECO mode switch allows the engine speed to automatically adjust to the load, improving fuel efficiency and reducing noise when less power is required.
- Flip the ECO mode switch to 'ON' for quieter operation and better fuel economy when powering light loads.
- Flip the ECO mode switch to 'OFF' when powering heavy loads or starting appliances with high surge requirements.
Stopping the Generator:
- Disconnect all electrical loads from the generator.
- Move the 3-in-1 switch to the 'OFF' position.
- Turn the fuel valve to the 'OFF' position.
- Allow the generator to cool completely before storing.
