Fill the fuel tank with fresh, unleaded gasoline. The fuel tank capacity is approximately 0.95 gallons (3.6 liters).
- Unscrew the fuel tank cap.
- Carefully pour gasoline into the tank using a funnel. Do not overfill.
- Securely replace the fuel tank cap.
3.4. Connecting Water Supply
Connect a garden hose to the pressure washer's water inlet. Ensure the water filter is properly inserted into the pump inlet to prevent debris from entering the pump.

- Turn the engine switch to the "ON" position.
- Open the fuel valve.
- Move the choke lever to the "CLOSE" position (for cold starts). If the engine is warm, move it to "OPEN".
- Locate the recoil cord and pull it slowly until resistance is felt, then pull rapidly to start the engine.
- Once the engine starts, gradually move the choke lever to the "OPEN" position.
4.2. Using Quick-Connect Nozzles
The pressure washer comes with 5 quick-connect nozzles for various cleaning tasks:
- 0° (Red): Intense pencil-point jet for stubborn stains and hard-to-reach areas. Use with extreme caution.
- 15° (Yellow): Focused spray for heavy-duty cleaning of hard surfaces like concrete and brick.
- 25° (Green): General cleaning spray for decks, patios, and fences.
- 40° (White): Wide, gentle spray for delicate surfaces like vehicles, windows, and furniture.
- Soap (Black): Low-pressure spray for applying detergent.
