    Abstract: 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.

    Abstract: 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.

    Abstract translation: 旋转锤适于对工具头施加轴向冲击。 旋转锤包括马达，联接到马达的主轴，用于接收来自马达的转矩，以及至少部分地容纳在主轴内用于在其中往复运动的活塞。 曲柄毂联接到电动机以接收来自电动机的转矩。 曲柄轮毂限定旋转轴线并且包括从旋转轴线偏移的插座。 销包括至少部分地容纳在所述插座内的第一部分和固定到所述活塞的第二部分。 销的第一部分可在插座内枢转并且响应于曲柄毂的旋转而相对于插座轴向移位，用于使活塞在主轴内的最前部位置和主轴内的最后位置之间往复运动。

    Abstract: 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.
