摘要： 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.

摘要： A track saw assembly is provided including a track saw (i.e., a circular saw) having a shoe translatable upon a track. Various mechanisms control plunging of a saw unit and saw blade of the track saw relative to the shoe. For example, a plunge lockout mechanism is provided to prevent engagement of a trigger and prevent movement of a plunge mechanism. Various mechanisms control bevel angle adjustment of the saw unit relative to the shoe. For example, a linkage is provided and is operable to shift between a first position and a second position. In the first position, a bevel angle is restricted within a first bevel angle range. In the second position, the bevel angle is restricted within an expanded second bevel angle range. Other concepts relate to the interface between the shoe and the track and a clamp which secures the track to a workpiece.

摘要： A rotary hammer is adapted to impart axial impacts to a tool bit. The rotary hammer includes a motor, a spindle coupled to the motor for receiving torque from the motor, and a piston at least partially received within the spindle for reciprocation therein. A crank hub is coupled to the motor for receiving torque from the motor. The crank hub defines a rotational axis and includes a socket offset from the rotational axis. A pin includes a first portion at least partially received within the socket and a second portion fixed to the piston. The first portion of the pin is both pivotable within the socket and axially displaceable relative to the socket in response to rotation of the crank hub for reciprocating the piston between a forward-most position within the spindle and a rearward-most position within the spindle.

摘要： A vibrating screed comprising a screed member, a motor, and an exciter assembly configured to vibrate the screed member in response to receiving torque from the motor via a driveshaft. The exciter assembly includes a first eccentric mass fixed on the driveshaft and a second eccentric mass axially and rotationally moveable along the driveshaft between a first position and a second position in which the second eccentric mass is axially closer to the first eccentric mass than in the first position. The vibrating screed further comprises a mode selection member to switch the exciter assembly between a first, low vibration mode, in which the second eccentric mass is in the first position, and a second, high vibration mode, in which the second eccentric mass is in the second position.

摘要： A dust collector for use with a hand-held power tool. The dust collector includes a housing, a motor positioned in the housing, and a telescoping suction pipe coupled to the housing. The dust collector also includes a suction fan coupled to the motor and operable to generate a vacuum in the suction pipe. The dust collector further includes a dust container coupled to the housing and positioned upstream of the suction fan, and a filter at least partially arranged in the dust container. The dust collector also includes a filter cleaning mechanism including a solenoid configured to be actuated by a controller to dislodge dust from the filter when either the motor or the suction fan transitions from an active state to an inactive state.
