Abstract: A percussion tool including a parking assembly movable relative to a spindle. The parking assembly includes a seat coupled to the spindle, a first shuttle portion movable relative to an outer surface of the spindle, a biasing member positioned between the seat and the first shuttle portion, a second shuttle portion movable relative to the outer surface of the spindle, a bushing positioned within the spindle and configured to receive a portion of an anvil, and a fastener that couples the second shuttle portion to the bushing. The first shuttle portion and the second shuttle portion are movable together between a working position, in which a plurality of radial air vents in the spindle is closed, and an idle position, in which the plurality of radial air vents is open. The biasing member is configured to bias the first shuttle portion and the second shuttle portion into the idle position.
