    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.

    Abstract: A dust collector for use with a power tool comprises a housing, a telescoping suction pipe coupled to the housing, a suction fan positioned in the housing and operable to generate a vacuum in the suction pipe, a dust container coupled to the housing and positioned upstream of the fan, a filter at least partially arranged in the dust container, and a filter cleaning mechanism. The filter cleaning mechanism includes an anvil, a striker moveable between a first striker position, in which the striker is spaced from the anvil, and a second striker position, in which the striker is in contact with the anvil. The filter cleaning mechanism further includes an actuator moveable between a first actuator position and a second actuator position, in which the actuator is moved closer to the anvil than in the first position, and a first spring biasing the striker toward the anvil.
