6. Operating the Pressure Washer
Once set up, your pressure washer is ready for use. Always ensure you are wearing appropriate safety gear.
Starting and Stopping:

- To Stop: Release the spray gun trigger. The motor will stop automatically. For complete shutdown, turn the power switch to the 'OFF' position and disconnect from the power supply.
Using the Nozzles:
The pressure washer comes with an adjustable nozzle and a rotary nozzle, allowing you to select the appropriate spray pattern for different cleaning tasks.
- Adjustable Nozzle: Twist the nozzle to change the spray pattern from a concentrated jet for tough dirt to a wider fan spray for general cleaning.
- Rotary Nozzle: Provides a powerful, pulsating jet for stubborn dirt and grime on hard surfaces like concrete.
Using the High Pressure Foam Sprayer:
The foam sprayer is ideal for applying detergent or cleaning solutions. Fill the foam sprayer bottle with your desired cleaning solution, attach it to the spray gun, and activate the pressure washer. The unit will mix the solution with water to create a rich foam.
