4. Setup
Before operating your generator, proper setup is crucial for safety and performance.
4.1 Adding Engine Oil:
- Place the generator on a level surface.
- Locate the oil fill cap/dipstick.
- Carefully add the recommended engine oil (refer to specifications for type and capacity) until it reaches the upper mark on the dipstick. Do not overfill.
- Securely replace the oil fill cap.
4.2 Adding Fuel:
- Ensure the generator is turned off and cool.
- Move the generator to a well-ventilated outdoor area, away from ignition sources.
- Unscrew the fuel cap.
- Slowly pour fresh, unleaded gasoline into the fuel tank, avoiding spills. Do not fill to the very top; leave space for expansion.
- Securely replace the fuel cap. Wipe up any spilled fuel immediately.
5. Operating Instructions
Follow these steps for safe and effective operation of your SG2500i generator.
5.1 Starting the Generator:
- Ensure the generator is on a level surface outdoors.
- Turn the fuel valve to the "ON" position.
- Move the choke lever to the "CHOKE" position (if the engine is cold).
- Turn the engine switch to the "ON" position.
- Pull the recoil starter handle firmly and smoothly until the engine starts.
- Once the engine starts, gradually move the choke lever to the "RUN" position.
5.2 Connecting Electrical Devices:
- Allow the generator to run for a few minutes to warm up.
- Plug your devices into the 230V AC outlets or the 2.1A USB ports.
- Ensure the total wattage of connected devices does not exceed the generator's maximum output (2000W).
- ECO Mode: For lighter loads, switch to ECO mode to reduce engine speed, save fuel, and lower noise levels. The generator will automatically adjust engine speed to match the load.
