5. Operating
5.1 Starting the Generator
- Ensure the generator is on a level surface and all electrical loads are disconnected.
- Check engine oil and fuel levels.
- Turn the fuel valve to the ON position.
- Set the engine switch to the START position.
- If the engine is cold, apply choke.
- Pull the recoil starter handle firmly until the engine starts. It may require several pulls.
- Once started, gradually push the choke back to the RUN position.
- Allow the engine to warm up for a few minutes before connecting electrical loads.
5.2 Connecting Electrical Devices
Connect your devices to the appropriate outlets (230V AC, 12V DC, or USB). Ensure the total load does not exceed the continuous power output of 3200W (or 3500W peak).
5.3 ECO Mode
Activate the ECO mode switch for quieter operation and improved fuel economy when running light loads. The engine speed will automatically adjust to the load.
5.4 Stopping the Generator
- Disconnect all electrical loads.
- 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. Maintenance
Regular maintenance ensures the longevity and reliable performance of your generator.
- Engine Oil: Check oil level before each use. Change oil after the first 20 hours of operation, then every 100 hours or annually.
- Air Filter: Inspect and clean the air filter every 50 hours or more frequently in dusty conditions. Replace if damaged.
- Spark Plug: Inspect and clean the spark plug every 100 hours. Replace if necessary.
- Fuel Filter: Inspect periodically and replace if clogged.
