4. Operating Instructions

Before starting, ensure all connections are secure and the water supply is turned on.

2. Start the Pressure Washer: Turn the ON/OFF switch to the 'ON' position. The motor will start.
3. Begin Cleaning: Aim the nozzle at the surface to be cleaned, maintaining a safe distance. Squeeze the trigger on the high-pressure gun to start the water jet.
