2. Attach the Battery: Slide the charged battery into the battery slot at the base of the pressure washer body until it clicks securely into place.
3. Connect the Extension Rod and Nozzle: Attach the extension rod to the front of the pressure washer body. Then, connect the 6-in-1 adjustable nozzle to the end of the extension rod. Ensure both connections are secure.
4. Connect the Hose: Attach one end of the 16.5ft hose to the water inlet quick connector on the pressure washer body. Place the other end of the hose, with the hose filter attached, into a clean fresh water source (e.g., bucket, lake, pool). The filter prevents debris from entering the pump.

2. Prime the Pump (First Use or After Dry Storage): Before starting, ensure the hose filter is fully submerged in water. Squeeze the trigger for a few seconds to allow water to flow through the pump and expel any air.
3. Start Cleaning: Aim the nozzle at the surface to be cleaned and press the trigger to activate the water flow. Release the trigger to stop.
4. Using Detergent: If using the detergent container, ensure it is filled with appropriate cleaning solution and attached. Select the "foam jet" setting on the nozzle for optimal foam application.
5. Adjusting Pressure: The pressure output is primarily controlled by the nozzle setting. For stubborn stains, use the 0° high-pressure mode. For wider coverage or delicate surfaces, use wider spray angles or the shower mode.

Maintenance

  • Disconnect the water source and run the pressure washer for a few seconds to clear any remaining water from the pump and hose.
  • Remove the battery.
  • Clean the exterior of the unit with a damp cloth.
  • Rinse the hose filter to remove any trapped debris.
• Battery Care:
