Setup and Assembly
- Charge the Battery: Insert the 2.0 Ah battery pack into the fast charger. Connect the charger to a 220-240V ~ 50/60Hz power outlet. The indicator light on the charger will show the charging status. Ensure the battery is fully charged before first use.
- Attach the Spray Gun: Align the spray gun with the main unit and push it firmly until it clicks into place.
- Select a Nozzle: Choose the appropriate spray pattern nozzle for your task. Insert the desired nozzle into the end of the spray gun and twist to secure it. The unit includes 6 different spray patterns for various applications.
- Connect Water Supply:
- Hose Connection: Attach the 6-meter water inlet hose to the water inlet port on the pressure washer unit using the quick connector. Ensure a secure fit.
- Self-Suction: For drawing water from a bucket or other container, attach the self-suction connector to the water inlet hose and place the filter end into the water source.
- Attach Foam Bottle (Optional): If using detergent, fill the 400ml foam bottle with appropriate pressure washer detergent. Attach the foam bottle to the spray gun as instructed in the foam bottle's specific manual.

Operating Instructions
- Insert Battery: Once the unit is assembled and connected to a water source, insert the charged battery pack into the battery slot on the pressure washer unit.
- Prime the Pump: Before starting, ensure water flows freely through the hose and unit to remove any air. Squeeze the trigger without the battery inserted until water flows out of the nozzle.
- Start the Washer: Point the nozzle away from yourself and others. Press the power button or squeeze the trigger to start the pressure washer. The unit features an automatic stop system that activates when the trigger is released.
- Adjust Spray Pattern: Rotate the nozzle head to select the desired spray pattern (e.g., narrow jet for stubborn dirt, wide fan for general cleaning).
- Cleaning Technique: Hold the nozzle at an appropriate distance from the surface to be cleaned. Start with a wider spray pattern and lower pressure, gradually moving closer or selecting a narrower pattern if needed. Always test on an inconspicuous area first.
- Using Detergent: If using the foam bottle, ensure it is filled with suitable pressure washer detergent. The foam bottle will mix the detergent with the water stream. Apply detergent to the surface, allow it to soak (do not let it dry), then rinse thoroughly with clean water.
- Shutting Down: Release the trigger. Disconnect the water supply. Squeeze the trigger to release any remaining pressure in the system. Remove the battery pack.
Maintenance and Storage
- Cleaning: After each use, flush the system with clean water to remove any detergent residue. Wipe down the exterior of the unit with a damp cloth.
- Nozzle Care: Regularly check nozzles for blockages. Use a small pin or needle to clear any debris from the nozzle opening.
- Water Filter: Inspect the water inlet filter regularly and clean it if necessary to prevent debris from entering the pump.
- Battery Care: Store the battery pack in a cool, dry place away from direct sunlight and extreme temperatures. Do not store fully discharged. Charge the battery periodically if not used for extended periods.
- Winter Storage: If storing in an area where temperatures may drop below freezing, ensure all water is drained from the pump and hoses to prevent damage from freezing. Consider using a pump protector.
- Storage: Store the pressure washer and all accessories in the provided portable carry bag in a dry, secure location, out of reach of children.
