Abstract

A method for controlling an airless sprayer (10) having an electronic control (12) with a user selectable pressure setpoint monitors the actual output pressure developed by the pump (14). When the pump output pressure drops to a selectable percentage of the setpoint, the control displays an empty message and the unit shuts off.
