An automatic lubricator for lubricating an object is provided. The lubricator includes a housing with a coupling section configured to couple with a lubricant container containing a lubricant, wherein the lubricant container comprises a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. The lubricator further comprises an electric motor configured to drive the rotatable shaft of the lubricant container, such that at least a part of the lubricant is dispensable from the lubricant container, at least one sensor configured to provide a sensor signal indicative of at least one of a force exerted by the electric motor onto the rotatable shaft and a force exerted by the lubricant onto the container, and a control circuitry configured to determine a blockage of the output of the lubricant container based on the sensor signal of the at least one sensor.
