Abstract
A power tool arrangement includes a frame having an outlet. A power tool is coupled to the frame and includes a movable working element configured to engage a work piece. A hose includes first and second opposite ends and a biasing device configured to bias the hose into a longitudinally compressed position. The first end is coupled to the outlet. The second end is coupled to the working element such that the second end follows the movement of the working element and the hose thereby moves between the longitudinally compressed position and a longitudinally expanded position.
