Setup
- Charge the Battery: Connect the lithium battery to the charger and plug the charger into a power outlet. Ensure the battery is fully charged before first use.
- Attach the Battery: Slide the charged battery into the battery compartment at the base of the pressure washer until it clicks securely into place.
- Connect Water Inlet Hose: Attach the water inlet hose to the pressure washer's water intake port. Ensure the water filter is securely attached to the other end of the hose.
- Prepare Water Source: Place the filtered end of the water inlet hose into a clean water source, such as a bucket, river, or connect it to a faucet using the quick connector if available. The device supports self-priming from various sources.
- Attach Nozzle/Accessory: Select the desired nozzle (e.g., adjustable nozzle) or accessory (e.g., foam pot) and securely attach it to the spray wand.

Operating Instructions
- Power On: Press the power button to turn on the pressure washer. The motor will start.
- Prime the Pump (First Use or After Dry Storage): Before spraying, allow the pump to run for a few seconds to draw water and expel any air from the system.
- Adjust Spray Pattern: If using the adjustable nozzle, rotate the nozzle head to select the desired spray pattern (e.g., 0° direct injection, 20° fan spray, 45° wide fan spray).
- Apply Foam (Optional): If using the foam pot, fill it with appropriate cleaning solution and attach it to the spray wand. The pressure washer will mix the solution with water to create foam.
- Begin Cleaning: Direct the spray at the surface to be cleaned, maintaining a safe distance. Move the spray wand steadily to ensure even cleaning.
- Power Off: Release the trigger and press the power button to turn off the device after use.
