Abstract: A rotary hammer includes a motor and a spindle coupled to the motor for receiving torque from the motor. The spindle has an adjustable rotation speed. A reciprocation mechanism is operable to create a variable pressure air spring within the spindle and includes a piston configured to reciprocate within the spindle in response to receiving torque from the motor. The piston has an adjustable reciprocation frequency. A striker is selectively reciprocable within the spindle in response to reciprocation of the piston. A first transmission is transfers torque from the motor to the spindle and a second transmission is transfers torque from the motor to the reciprocation mechanism. The reciprocation frequency of the piston is adjustable independent of the rotation speed of the spindle. The rotation speed of the spindle is adjustable independent of the reciprocation frequency of the piston. At least one of the transmissions is a multi-speed transmission.

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.

Abstract: A power tool includes an output shaft defining a rotational axis and a housing from which the output shaft protrudes. The power tool further includes a flange at least partially surrounding the output shaft, a circumferential groove defined between the housing and the flange, and a radially inward-extending slot in the flange. The power tool also includes a rotatable guard having a first radially inward-extending projection and a plurality of apertures positioned radially about the rotational axis. The first radially inward-extending projection is receivable through the radially inward-extending slot in the flange and positioned within the groove. Furthermore, the power tool includes a lever having a detent member, and a biasing member for biasing the lever toward the rotatable guard. The detent member is receivable in one of the plurality of apertures to rotationally lock the rotatable guard relative to the housing.

Abstract: A rotary hammer includes a housing, a first motor supported by the housing and defining a first motor axis, a second motor supported by the housing and defining a second motor axis that is coaxial with the first motor axis, and a spindle coupled to the first motor for receiving torque from the first motor, causing the spindle to rotate. The rotary hammer further includes a reciprocation mechanism operable to create a variable pressure air spring within the spindle. The reciprocation mechanism includes a piston configured to reciprocate within the spindle in response to receiving torque from the second 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.
