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.

A power tool includes a housing, a motor, a switching network electrically coupled to the motor, and a printed circuit board positioned at an angle within the housing. The power tool further includes a user input configured to receive a sensitivity level for loss of control detection, a sensor configured to measure an acceleration of the housing with respect to at least two axes, and an electronic processor coupled to the switching network. The electronic processor is configured to receive one or more signals related to the acceleration of the housing of the power tool from the acceleration sensor, determine that the one or more signals exceed an acceleration threshold corresponding to the sensitivity level for loss of control detection, and control the switching network to brake the brushless DC motor in response to the one or more signals exceeding the acceleration threshold.
