4. Setup and Assembly

4.1 Battery Charging

Before first use, fully charge both 4Ah batteries. Connect the charger to a power outlet and then to the battery. The charging indicator on the battery or charger will show the charging status. A full charge typically takes 4 to 5 hours.

4.2 Assembling the Pressure Washer

1. Insert a fully charged battery into the battery slot on the main unit until it clicks into place.
2. Attach the extension wand to the main unit by aligning the connectors and twisting until secure.
3. Select the desired nozzle (6-in-1 or 180° pivoting) and attach it to the end of the extension wand. Ensure it is firmly in place.
4. Connect the 5-meter water hose to the water inlet on the main unit using the provided connector.
5. Place the water filter end of the hose into your chosen water source (e.g., bucket of water). Ensure the filter is fully submerged.

Note: The water drop should not exceed 1.5 meters, as this may affect pumping performance. Seawater is prohibited to prevent corrosion of internal components.

5. Operating Instructions

5.1 Powering On and Adjusting Pressure

Press the power button on the unit to turn it on. The power display will illuminate. Use the '+' and '-' buttons to switch between the two pressure settings:

• Low Pressure (25 bar): Ideal for watering plants or light cleaning tasks.
• High Pressure (65 bar): Suitable for more demanding cleaning, such as cars, fences, or floors.

The battery provides a maximum runtime of 45 minutes per battery in low-pressure mode.

5.2 Nozzle Usage

The 6-in-1 nozzle allows you to select different spray patterns by rotating its front. The 180° pivoting nozzle offers additional flexibility for reaching awkward angles.

• 0° Jet: For concentrated, powerful cleaning of stubborn dirt.
• 15°, 25°, 40° Fan Spray: For general cleaning of various surfaces.
• Shower Mode: Gentle spray for watering plants.
• Foam Jet: For applying cleaning solutions with the foam sprayer.

Warning: Do not change nozzles while spraying water.

5.3 Using the Foam Sprayer

Fill the foam sprayer bottle with your desired cleaning solution. Attach it to the pressure washer in place of the standard nozzle. Select the "Foam Jet" setting on the 6-in-1 nozzle (if using) or use the dedicated foam sprayer nozzle to apply foam evenly to the surface. After applying foam, remove the foam sprayer and rinse the surface with a suitable spray pattern.

6. Maintenance

6.1 Cleaning the Unit

After each use, disconnect the battery and water hose. Rinse the nozzles and extension wand with clean water to remove any residue. Wipe the main unit with a damp cloth. Do not use harsh chemicals or abrasive cleaners.

6.2 Water Filter Maintenance

Regularly inspect and clean the water filter to ensure optimal performance and prevent clogging. Remove any debris or sediment from the filter mesh.

6.3 Storage

Store the pressure washer and its accessories in the provided carrying case in a dry, cool place, away from direct sunlight and extreme temperatures. Ensure batteries are partially charged before long-term storage.

7. Troubleshooting

7.1 Unit Not Pumping Water

If the unit is not pumping water, the internal rubber gasket may stick to the water inlet due to dryness.

• Solution: Pour a small amount of water into the water inlet and simultaneously start the machine. This helps to soften the rubber gasket and initiate pumping.

7.2 Low Pressure Output

• Check battery charge level.
• Ensure the water filter is clean and not clogged.
• Verify that the water source is adequate and the hose is not kinked.
• Confirm the correct nozzle and pressure setting are selected.

7.3 Unit Not Turning On

• Ensure the battery is fully charged and correctly inserted.
• Try using the second battery provided.
