5. Operating Instructions
- Preparation: Ensure all connections are secure and the water supply is fully open.
- Priming the Pump: Before switching on the motor, squeeze the trigger on the spray handle to allow water to flow through the system and expel any air. Continue until a steady stream of water emerges.
- Starting the Unit: Switch on the pressure washer. The induction motor will start, and the pump will build pressure.
- Using the Spray Handle: Squeeze the trigger to activate the high-pressure jet. Release the trigger to stop the flow.
- Changing Nozzles: To change nozzles, turn off the unit and release any residual pressure by squeezing the trigger. Detach the current nozzle and attach the desired ClickClean nozzle.

- Shutting Down: Turn off the pressure washer. Turn off the water supply. Squeeze the trigger to release any remaining pressure in the system. Disconnect the water hose and power cable.
6. Maintenance
- Nozzle Cleaning: Regularly clean the nozzles using the provided nozzle jet cleaning tool to prevent blockages and maintain optimal spray patterns.

- Hose and Connections: Inspect the high-pressure hose and all connections for wear, damage, or leaks before each use. Replace damaged parts immediately.
- Storage: Store the pressure washer in a dry, frost-free environment. Ensure all water is drained from the pump and hose before storing to prevent freezing damage. Utilize the hose reel for neat storage of the high-pressure hose.
