Operating Instructions
1. Starting the Engine
- Ensure the fuel valve is open and the engine switch is in the 'ON' position.
- Move the choke lever to the 'CHOKE' position (if the engine is cold).
- Pull the recoil starter handle firmly until the engine starts.
- Once started, gradually move the choke lever to the 'RUN' position.
2. Using Quick-Connect Nozzles
The pressure washer comes with 5 quick-connect nozzles for various cleaning tasks. To change a nozzle, pull back the collar on the spray gun wand, insert the desired nozzle, and release the collar to lock it in place. Always ensure the nozzle is securely seated before operating.
- 0° (Red): Pin-point stream for tough, concentrated cleaning. Use with caution.
- 15° (Yellow): Narrow spray for intense cleaning of small areas.
- 25° (Green): Wider spray for general cleaning tasks.
- 40° (White): Widest spray for gentle cleaning and rinsing.
- Soap (Black): Low-pressure spray for applying detergent.

3. Applying Detergent
To apply detergent, ensure the soap nozzle (black) is installed. The pressure washer will automatically draw detergent from the on-board tank at low pressure. After applying detergent, switch to a high-pressure nozzle (e.g., 25° or 40°) to rinse the surface thoroughly.

- Turn off the water supply.
- Squeeze the spray gun trigger to release any remaining pressure in the system.
