- Using the Draw Hose: Attach the 20’ draw hose to the quick connect adapter (WA4017), then connect the adapter to the water inlet on the pressure washer. Place the other end of the draw hose into a bucket, lake, or any fresh water source. Ensure the filter on the end of the hose is submerged.
- Using a Garden Hose: For continuous water supply, connect a standard garden hose directly to the water inlet on the pressure washer.
- Using a 2-Liter Bottle: For ultimate portability, attach the bottle cap adapter (WA4038) to a standard 2-liter bottle filled with water, then connect it to the water inlet.
- Prime the Pump: Before starting, ensure the unit is properly primed. Point the nozzle away from yourself and others, then press the trigger for a few seconds until a steady stream of water emerges.
5. Operating Instructions
- Power On: Ensure the battery is inserted and the water source is connected. The unit is ready for operation.
- Adjust Nozzle Settings: The 5-in-1 multi-spray nozzle allows you to select different spray patterns and pressures by rotating the nozzle head. The settings include:
- 0° (Pencil Jet): For concentrated, high-impact cleaning on tough spots.
- 15° (Narrow Fan): For intensive cleaning over a smaller area.
- 25° (Medium Fan): A balanced spray for general cleaning tasks.
