A quick change chain saw system includes a swing arm and a hydraulic clamp device. The swing arm extends from the hydraulic clamp device. The swing arm retains drive sprocket components and is retained by a tree harvester or wood processor unit. The hydraulic clamp device includes a hydraulic clamp block, a puck plate, a clamp plate and a detent pin. The puck plate includes a base plate and three stud projections that is actuated with a plurality of pucks in the hydraulic clamp block. Three stud projections extend from the base plate and are inserted through the hydraulic clamp block. The clamp plate is secured to the three stud projections. A spring tensioner is used to bias the chain bar. A retraction tool is used to retract the hydraulic clamp device. The detent pin is used keep the hydraulic clamp in a retracted position for changing the chain blade.
