Operating Instructions

Once set up, operate your pressure washer as follows:

1. Adjust Spray Pattern: Rotate the adjustable nozzle at the end of the wand to select your desired spray intensity and pattern. You can choose from a concentrated jet for stubborn dirt to a wide fan spray for rinsing larger areas.
2. Initiate Water Flow: Aim the nozzle away from yourself and others. Squeeze the trigger on the handle to begin the water flow. Release the trigger to stop the flow.
3. Begin Cleaning: Direct the spray towards the surface you wish to clean. Maintain an appropriate distance to avoid damaging the surface. For best results, start with a wider spray and adjust to a narrower jet as needed for tougher spots.
