3. Operating Instructions

Follow these steps for safe and effective operation of your pressure washer.

3.1 Starting the Engine

  1. Ensure the unit is on a level surface.
  2. Turn the engine switch to the 'ON' position.
  3. Open the fuel valve.
  4. Set the choke lever to the 'CHOKE' position (cold start) or 'RUN' position (warm start).
  5. Pull the recoil starter handle firmly until the engine starts.
  6. Once the engine starts, gradually move the choke lever to the 'RUN' position.

3.2 Using Nozzles and Detergent

The pressure washer includes 4 Quick Connect nozzles (0°, 15°, 40°, Soap) and a Turbo nozzle for various cleaning tasks.

  • 0° (Red): Concentrated, high-pressure stream for tough, localized stains. Use with caution.
  • 15° (Yellow): Narrow fan spray for heavy-duty cleaning and stripping.
  • 40° (White): Wide fan spray for general cleaning of delicate surfaces.
  • Soap (Black): Low-pressure spray for applying detergent.
  • Turbo Nozzle: Rotates a 0° stream in a circular motion for intense cleaning over a wider area.

To apply detergent, use the black soap nozzle. The unit will automatically draw detergent from the soap tank at low pressure. After applying detergent, switch to a high-pressure nozzle (e.g., 15° or 40°) to rinse the surface thoroughly.
