4. Setup
Follow these steps to set up your Aihand Cordless Pressure Washer for operation:
- Install the Battery: Ensure the 21V 4.0Ah battery is fully charged. Align the battery with the slot at the base of the pressure washer handle and slide it in until it clicks securely into place.
- Connect the Water Hose: Attach the 16.5 ft water hose to the water inlet on the pressure washer unit. Ensure the connection is tight to prevent leaks. Place the filter basket end of the hose into your chosen water source (e.g., bucket of water, lake).
- Attach Nozzle/Accessory: Choose the appropriate nozzle or accessory for your task.
- For 6-in-1 or High/Low Pressure Nozzle: Press and rotate the nozzle onto the end of the pressure washer or extension pole until it locks.
- For Foam Cannon: Attach the foam cannon to the end of the pressure washer or extension pole. Fill the 400ml container with your desired cleaning solution.
- For Extension Pole: If extra reach is needed, connect the extension pole to the pressure washer unit, then attach your chosen nozzle/accessory to the end of the extension pole.
- For Cola Bottle Adapter: Screw the cola bottle adapter onto a standard plastic bottle filled with water, then press the adapter into the water inlet of the pressure washer.
- Priming the Pump (Important for first use or if water is not spraying): If the unit is not spraying water, remove the water inlet pipe. Press and hold the power button while continuously filling water into the inlet until water sprays from the nozzle. Please avoid letting water enter the pressure washer's internal components.

5. Operating Instructions
Once your pressure washer is set up, follow these guidelines for effective and safe operation:
- Start the Unit: Press the power button on the handle to start the pressure washer. The unit will begin drawing water and spraying.
- Select Spray Pattern (6-in-1 Nozzle): Rotate the head of the 6-in-1 nozzle to select your desired spray pattern: 0° (pencil jet), 15°, 25°, 40° (fan spray), Fan-Shaped Mode, or Shower Mode. Choose a pattern appropriate for the cleaning task and surface.
- Apply Detergent (with Foam Cannon): If using the foam cannon, ensure it is filled with detergent. The foam cannon allows you to adjust the amount of foam dispensed. Spray the detergent onto the surface, allowing it to soak for a few minutes before rinsing.
- Cleaning Technique: Hold the nozzle a safe distance from the surface to avoid damage. Start with a wider spray pattern and lower pressure on delicate surfaces, gradually increasing as needed. Move the nozzle in a sweeping motion to ensure even cleaning.
- Stop the Unit: Release the power button to stop the water flow. For prolonged breaks or when finished, remove the battery.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Aihand Cordless Pressure Washer:
- Clean the Water Filter: Regularly inspect and clean the filter basket on the water hose to remove any accumulated debris. A clogged filter can reduce water flow and pressure.

- Store Properly: Store the pressure washer, battery, and accessories in the provided storage case in a dry, cool place, away from direct sunlight and extreme temperatures.
- Battery Care: Store the battery in a charged state. If storing for extended periods, charge the battery every 3-6 months to maintain its health.
- Winterization: In cold climates, ensure all water is drained from the unit and hose before storing to prevent freezing and damage.
