    Abstract: A charger for an electrical device (e.g., site light) includes a housing defining an interior cavity, and one or more openings formed in the housing. The one or more openings fluidly communicate the interior cavity with an exterior of the charger. A heat sink is at least partially disposed in the housing and operable to dissipate heat produced in the housing. A first portion of the heat sink is positioned within the interior cavity. A second portion of the heat sink is positioned in the one or more openings such that the heat sink is at least partially exposed to the exterior. The heat sink is in heat transfer relationship with components of charger electronics of the charger.

    Abstract: An impact mechanism for use in a power tool having a motor and adapted to impart axial impacts to a tool bit. The impact mechanism includes a piston configured to reciprocate in response to receiving torque from the motor, a striker that is selectively reciprocable within the spindle in response to reciprocation of the piston, and an anvil that is impacted by the striker when the striker reciprocates towards the tool bit. The anvil imparts axial impacts to the tool bit. The striker includes a body portion formed of a first material and an insert portion within the body portion. The insert portion is formed of a second material that is more dense than the first material.

    Abstract: A rotary hammer is adapted to impart axial impacts to a tool bit. The rotary hammer comprises a housing, a motor supported by the housing, a gearcase, and a spindle housed in the gearcase and coupled to the motor for receiving torque from the motor, causing the spindle to rotate. The rotary hammer also comprises a reciprocating impact mechanism operable to create a variable pressure air spring within the spindle. The rotary hammer also comprises a vibration damping mechanism including a base on the gearcase, a counterweight circumscribing the base, and a first spring arranged between the base and the counterweight and defining a first biasing axis that is parallel to the reciprocation axis. The vibration damping mechanism also includes a second spring arranged between the base and the counterweight and arranged along the first biasing axis.
