A method of operating a drink-blending machine to change the operational speed of an ice-shaver motor initiates operation of an ice-shaving process to supply a portion of shaved ice to a pitcher. Accordingly, the ice is moved past a blade to produce shaved ice. According to the rate of ice-shaving, the operational speed of the ice-shaver motor is adjusted. In doing so, the method compensates for dullness of the blade to maintain rate of ice-shaving with a specified range.
