2. Water Source Connection
Choose one of the following methods for water supply:
- Standard Garden Hose: Connect a standard garden hose (not included) to the water inlet on the pressure washer unit. Ensure the hose is free of kinks and the water supply is turned on.
- Siphon Hose (Freshwater Source): Attach the 10' siphon hose to the water inlet. Place the other end of the siphon hose into a clean freshwater source (e.g., bucket, lake). Ensure the siphon hose is fully submerged and free of air bubbles for proper priming.

Operating Instructions
1. Priming the Pump (Siphon Hose Only)
If using the siphon hose, the pump needs to be primed:
- Ensure the siphon hose is fully submerged in water.
- With the battery installed, press the power button to turn on the unit.
- Squeeze the trigger on the handle and hold it open until a steady stream of water emerges from the nozzle, indicating the pump is primed. This may take a few moments.
2. Powering On and Mode Selection

- Select your desired operating mode:
- ECO Mode (900 PSI, 0.8 GPM): For lighter cleaning tasks and extended battery runtime.

3. Cleaning Operation
- Hold the trigger handle firmly with both hands.
- Direct the nozzle towards the surface to be cleaned, maintaining a safe distance to avoid damage.
- Squeeze the trigger to start the water flow. Release the trigger to stop.
- Move the spray in a sweeping motion, overlapping slightly to ensure even cleaning.
