4. Setup

4.1 Unpacking and Inspection

• Carefully remove the generator from its packaging.
• Inspect for any shipping damage. If damaged, contact your dealer immediately.
• Verify all included accessories are present: user manual, gas hose with pressure regulator, spark plug wrench, oil filling funnel, parallel connection cable, Schuko 16A plug, PH2 6.0mm screwdriver, battery charging terminals.

4.2 Adding Engine Oil

The engine is shipped without oil. You must add engine oil before first use.

1. Place the generator on a level surface.
2. Locate the oil fill cap/dipstick.
3. Using the provided funnel, slowly add 0.35 liters of recommended engine oil (e.g., SAE 10W-30) until it reaches the upper mark on the dipstick. Do not overfill.
4. Securely replace the oil fill cap.

4.3 Connecting Fuel

For Petrol Operation:

1. Ensure the generator is off and cool.
2. Open the fuel tank cap.
3. Fill the 4.0-liter fuel tank with unleaded petrol (octane 91-95). Do not overfill.
4. Securely close the fuel tank cap.

For LPG Operation:

1. Ensure the generator is off and cool.
2. Connect one end of the gas hose with pressure regulator to the generator's LPG inlet.
3. Connect the other end of the gas hose to a standard LPG gas bottle (DIN 477).
4. Ensure all connections are tight and leak-free.

5. Operating Instructions

5.1 Starting the Generator

Manual Start (Petrol):

1. Ensure the generator is on a level surface and away from flammable materials.
2. Set the fuel selector switch to 'Petrol'.
3. Turn the engine switch to 'ON'.
4. If cold, apply choke.
5. Pull the recoil starter handle firmly until the engine starts.
6. Once started, gradually open the choke (if used).

Manual Start (LPG):

1. Ensure the generator is on a level surface and away from flammable materials.
2. Set the fuel selector switch to 'LPG'.
3. Open the valve on the LPG gas bottle.
4. Turn the engine switch to 'ON'.
5. Pull the recoil starter handle firmly until the engine starts.

5.2 ECO Mode Operation

The ECO mode reduces engine speed when the electrical load is low, improving fuel efficiency and reducing noise.

• To activate ECO mode, press the 'ECO' switch on the control panel. The ECO indicator light will illuminate.
• To deactivate ECO mode for full power, press the 'ECO' switch again.

5.3 Parallel Connection (Optional)
