Abstract: A safe lift device for a slicing machine as provided which enables at least a portion of the slicing machine to be raised from the table or counter upon which it rests. Intermediate the two legs to be raised, a retention leg is pivotally attached to the slicing machine. Also connected to the slicing machine and the retention leg is a lever arm assembly.
