    摘要： A miter saw with a cutting alignment device includes a base with a work surface provided thereon. A bevel support is pivotable with respect to the base and a cutting blade is supported by the bevel support. A dust chute is adjustably secured to the bevel support and pivots with respect to the base when the bevel support pivots. The dust chute includes mounts that allow lateral adjustment of the dust chute with respect to the bevel support. A laser alignment device is positioned on the dust chute and configured to emit a beam of light toward the work surface. The dust chute includes a receptacle designed and dimensioned to releasably hold the laser alignment device. Because the laser alignment device is retained on the dust chute, adjustment of the dust chute also results in adjustment of a beam of light emitted from the laser alignment device.

    摘要翻译： 具有切割对准装置的斜切锯包括其上设置有工作表面的基部。 斜面支撑件相对于基座可枢转，并且切割刀片由斜面支撑件支撑。 灰尘斜槽可调节地固定到斜面支撑件，并且当斜面支撑件枢转时相对于基座枢转。 防尘槽包括安装件，其允许灰尘槽相对于斜面支撑件的横向调节。 激光对准装置位于防尘槽上，并配置成向工作表面发射光束。 防尘槽包括设计和尺寸的可释放地保持激光对准装置的插座。 由于激光对准装置保持在防尘槽上，因此灰尘槽的调节也导致从激光对准装置发射的光束的调节。

    摘要： A power tool includes an electric motor, a motor housing in which the electric motor is at least partially positioned, a blade drivably coupled to the motor for rotation about a first axis, and a blade housing in which the blade is at least partially positioned. The blade and the blade housing are pivotably coupled to the motor housing about a second axis substantially parallel to the first axis.

    摘要： An improved dust collection system for a miter saw comprising a hollow dust chute attached to a bevel post of a miter saw. The bevel post includes a top portion and a bottom portion and is pivotably attached to a miter saw table. The dust chute comprises an input port positioned to receive saw dust resulting from a cutting operation, an exit port and a funnel body extending from the input port to the exit port. At least a portion of the funnel body extends toward an opening located in a guard of a cutting arm assembly. The cutting arm assembly is pivotably connected to the top portion of the bevel post; wherein, the dust chute remains substantially stationary, as the cutting arm assembly is moved during the cutting operation.

    摘要： Embodiments of a power miter saw of the type which has an upper fixed blade guard for encasing upper reaches of an installed saw blade without encasing the blade arbor, and a lower swinging blade guard for covering the lower reaches of an installed blade when saw is in its rest position and for exposing the saw blade when moved to its operational position, the saw comprising an elongated linkage mechanism having opposite end portions interconnecting a frame support and the lower blade guard for moving the lower blade guard in response to movement of the saw between the rest and operational positions, such that the lower blade guard covers the lower reaches of the blade when the saw is in its rest position and uncovers the lower reaches of the blade when the saw is moved to its operational position, the linkage mechanism being configured to be selectively detachable from the frame support, thereby enabling the lower blade guard to be placed in at least first and second positions wherein the first position enables normal movement of the saw between its rest and operational positions, and the second position wherein the lower blade guard is raised to expose a blade arbor to facilitate changing of the blade.
