5. Operating Instructions

Your YKYI Cordless Pressure Washer is designed for ease of use and versatility.

1. Power On: Once assembled and connected to a water source, press the power button on the unit. The LED display on the back will show the battery level and current speed setting.
2. Adjust Speed Level: Use the '+' and '-' buttons on the LED display to select one of the 30 adjustable speed levels. Lower speeds are suitable for delicate surfaces like car paint or plants, while higher speeds are for tough dirt and stains.
3. Select Spray Pattern: If using the 6-in-1 multi-function nozzle, rotate the nozzle head to choose from 0°, 15°, 25°, 40°, concentrated jet, or shower mode. Select the pattern appropriate for your cleaning task.
4. Apply Foam (Optional): If using the foam pot, fill it with car wash fluid or appropriate cleaning solution. Attach it to the wand. The pressure washer will mix the solution with water to create foam for deep cleaning.
5. Begin Cleaning: Aim the nozzle at the surface to be cleaned and press the trigger. Maintain a safe distance from the surface, especially with higher pressure settings, to avoid damage.
6. Prime the Pump: If the unit does not spray immediately, release the trigger and allow the pump to prime by holding the unit below the water source for a few seconds, then press the trigger again.
