Abstract: A dust cover for a hammer work tool, a hammer work tool, and a method of attaching the same are disclosed. The hammer work tool includes a housing, a power cell enclosed inside the housing, a tool member, and a detachable dust cover. When attached, the dust cover prevents particulate matter from entering the housing. When detached, a housing opening uncovered by the dust cover provides access to the power cell for maintenance and repairs. During installation, a housing rim and a locking tab of the hammer work tool are respectively received by a groove and a locking tab receiver of the dust cover. Advantageously, the dust cover is durable, cost effective, and easily attached and detached without the use of additional tools.
