5. Operating Instructions
Before starting, ensure all connections are secure and the water tap is fully open.
- Purge Air: Squeeze the trigger on the high-pressure gun until a steady stream of water emerges, indicating that all air has been purged from the system.
- Start the Appliance: Switch on the pressure washer using the ON/OFF switch. The pump will start and build pressure.
- Begin Cleaning: Direct the water jet at the surface to be cleaned, maintaining a safe distance. Adjust the nozzle or switch to a different nozzle as needed for various cleaning tasks.
- Detergent Application: If using detergent, fill the detergent nozzle with appropriate pressure washer detergent. Attach the detergent nozzle to the gun. The pressure washer will automatically draw detergent and mix it with water at low pressure.
- Stopping Operation: Release the trigger on the gun. The motor will stop. For longer breaks, switch off the appliance at the ON/OFF switch.
- Shutting Down: After use, switch off the appliance, turn off the water tap, and squeeze the trigger to release any residual pressure in the system. Disconnect the power and water supply.

6. Maintenance and Storage
Regular maintenance ensures optimal performance and extends the lifespan of your pressure washer.
- Cleaning the Water Filter: Periodically check and clean the water filter located at the water inlet. Remove any debris to prevent blockages.
- Nozzle Maintenance: Clean nozzles regularly to ensure an even spray pattern. A clogged nozzle can reduce pressure and damage the pump.
- Hose and Cable Management: Utilize the integrated hose reel and cable storage to keep the high-pressure hose and power cable tidy and prevent damage.
- Winter Storage: In freezing temperatures, drain all water from the pump, hose, and accessories to prevent damage from ice expansion. Store the appliance in a frost-free environment.
- General Cleaning: Wipe down the exterior of the unit with a damp cloth. Do not use harsh chemicals.
