How to use

Connect the high-pressure hose and lance compatible with the unit, supply the machine with a clean water source and switch on according to the manufacturer's operating sequence. Adjust the pressure control to the appropriate level for the surface to be cleaned. Hold the lance at a safe distance from the surface and move it steadily to avoid damage from concentrated spray. For heavily soiled areas, use a suitable detergent compatible with cold-water operation and the selected nozzle. After use, flush the system with clean water, relieve pressure, and store hoses and accessories properly to extend service life.

Usage recommendations

Use low-pressure fan nozzles for delicate surfaces and narrow high-pressure nozzles for stubborn dirt; maintain safe working distances and wear appropriate protective equipment. Regularly check connections, seals and hoses for wear and perform scheduled maintenance to ensure reliable operation under professional workloads.
