Start the high-pressure system and adjust the water flow and system pressure using the nozzle selection, pump speed, and controlling unloader setting. To test the functionality of the mechanism, pull the trigger on the gun.
Place the sand induction probe inside the sand supply container. Adjust the tiny mixing head valve while the gun's trigger is open. By creating a vacuum in the sand hose line, the adjustment initiates the flow of sand. Sand is introduced to the system directly from a container through the sand point. The head's suction capabilities allow sand to be drawn into the head via the sand collection tube. In the head, sand and high-pressure water are combined. Through the nozzle, the resulting sand and water mixture is sprayed at high pressure across surfaces.
