3. Remove the cap and carefully add 1.1 liters of SAE10W40 engine oil. Do not overfill.
4. Replace the oil fill cap securely.

3.3 Adding Fuel

Use fresh, unleaded gasoline with an octane rating of 87 or higher.

1. Ensure the generator is off and cool.
2. Open the fuel tank cap.
3. Carefully pour gasoline into the tank, avoiding spills. The tank capacity is 25 liters. Do not fill above the maximum fill line.
4. Securely close the fuel tank cap.

3.4 Battery Connection (for Electric Start)

Connect the battery terminals for the electric start function.

1. Locate the battery compartment.
2. Connect the positive (+) battery cable (red) to the positive (+) battery terminal.
3. Connect the negative (-) battery cable (black) to the negative (-) battery terminal.
4. Ensure connections are tight. The battery features automatic shutdown during prolonged inactivity to prevent deep discharge.

4. Operating Instructions

This section details how to start, operate, and stop your GENERGY CRETA 7500W generator.

4.1 Starting the Generator

Ensure the generator is on a level surface and all initial setup steps have been completed.

1. Fuel Valve: Open the fuel valve.
2. Choke: If starting a cold engine, move the choke lever to the 'CHOKE' position. For a warm engine, set it to 'RUN'.
3. Engine Switch: Turn the engine switch to the 'ON' position.
4. Electric Start: Press and hold the electric start button until the engine starts. Release the button once the engine is running.
5. Remote Start: Alternatively, use the remote control to start the generator. Press the start button on the remote.
6. Choke Adjustment: Once the engine starts and runs smoothly, gradually move the choke lever to the 'RUN' position.

4.2 ECO-Drive Mode

The ECO-Drive mode helps conserve fuel and reduce noise levels.

• To activate ECO-Drive mode, switch the ECO-Drive switch to the 'ON' position. The engine speed will automatically adjust based on the connected load.
• For maximum power output or when connecting high-demand appliances, switch ECO-Drive mode to 'OFF'.

4.3 Connecting Electrical Devices

Ensure the generator is running stably before connecting any devices.

1. Plug your electrical devices into the appropriate outlets on the control panel.
2. Do not exceed the generator's rated wattage.
3. The generator includes 2 x 16 A (IP44) and 1 x 32 A (IP44) AC outlets, and a 12 V DC outlet.

4.4 Stopping the Generator

1. Disconnect all electrical loads from the generator.
2. Turn the engine switch to the 'OFF' position.
3. Close the fuel valve.
