1. A system for removing coke from a coking vessel comprising:
- a cutting head, said cutting head comprising a cutting nozzle, and a boring nozzle;
a flow diversion apparatus structured to block the flow of fluid to one of the cutting nozzles and the boring nozzles; and
a shifting apparatus structured to rotate the flow diversion apparatus coupled to the flow diversion apparatus, wherein the shifting apparatus is actuated when water pressure within the cutting head is decreased.
