Setup

1. Unpacking: Carefully remove the pressure cleaner and all accessories from the packaging.
2. Positioning: Place the unit on a firm, flat surface. The lashing rings and lever pedal facilitate transport and loading, making it easier to position the unit.
3. Water Supply Connection: Connect the pressure cleaner to a suitable water supply using a garden hose. Ensure the water supply is clean and free of debris.
4. Fuel Supply (for heating): Fill the fuel tank with the recommended type of fuel.
5. Electrical Connection: Connect the power cable to a grounded electrical outlet. This unit operates via an electric cable.
6. High-Pressure Hose and Spray Gun Assembly:
   • Attach the high-pressure hose to the outlet on the machine.
   • Connect the spray gun to the other end of the high-pressure hose.
   • Ensure all connections are secure to prevent leaks.

Operating Instructions
