A saw guard for attachment to a riving knife of a table saw includes a body portion having an elongated shape. The body portions defines a guard portion configured to cover a portion of a saw blade and an attachment portion. The attachment portion extends from the guard portion and defines a slot configured to receive the riving knife. The saw guard further includes an anchor piece connected to the body portion and arranged at least partially in the slot. The saw guard further includes an attachment assembly connected to the body portion and arranged at least partially in the slot and separated from the anchor piece. In a first configuration, the anchor piece and the attachment assembly may define a two-point attachment between the saw guard and the riving knife. In a second configuration, the attachment assembly may permit release of the saw guard from the riving knife.

Inserts for use in table saws are disclosed. One embodiment may include a mechanism to lock mechanically and affirmatively the insert in a blade opening in a table saw. The mechanism is designed so that a user can install and remove the insert without tools. The mechanism also can be designed so that the front of the insert pops up above the table when released from its locked position. The mechanism can be further designed so that the insert can be unlocked or released by a user pressing a button or tab.

A fence assembly configured to guide a workpiece with respect to a blade of a saw device includes a fence that is supported by rails for sliding movement relative to a work surface. Opposed ends of the fence are supported on the rails via rail engagement members. The fence assembly includes a fence angle adjustment mechanism associated with a housing of one of the rail engagement members. The fence angle adjustment mechanism includes biasing elements working in conjunction with an adjustment screw to adjust the position of the fence with respect to parallelism to the blade.

A saw guard for attachment to a riving knife of a table saw includes a body portion having an elongated shape. The body portions defines a guard portion configured to cover a portion of a saw blade and an attachment portion. The attachment portion extends from the guard portion and defines a slot configured to receive the riving knife. The saw guard further includes an anchor piece connected to the body portion and arranged at least partially in the slot. The saw guard further includes an attachment assembly connected to the body portion and arranged at least partially in the slot and separated from the anchor piece. In a first configuration, the anchor piece and the attachment assembly may define a two-point attachment between the saw guard and the riving knife. In a second configuration, the attachment assembly may permit release of the saw guard from the riving knife.

A self-dust extraction dustless table saw includes a table saw frame, saw table, and saw blade installed to the table saw frame. An upper and a lower blade guards are respectively mounted to upper and lower sides of the saw table, the saw blade is mounted in the upper and lower blade guards, and the lower blade guard includes a lower left and lower-right blade guards. Several interval guide barriers are installed on the inner walls of the lower left and lower right blade guards, and the guide barriers transport the dust to a dust outlet on the side of the lower right blade guard.

A power tool arrangement includes a frame having an outlet. A power tool is coupled to the frame and includes a movable working element configured to engage a work piece. A hose includes first and second opposite ends and a biasing device configured to bias the hose into a longitudinally compressed position. The first end is coupled to the outlet. The second end is coupled to the working element such that the second end follows the movement of the working element and the hose thereby moves between the longitudinally compressed position and a longitudinally expanded position.

A table saw includes a height adjustment wheel including a threaded shaft; a blade suspension mechanism secured to a lock crank; a rod secured to both the blade suspension mechanism and a bottom of the cutting surface; an electric motor including a driving shaft and a link extending forward to secure to the blade suspension mechanism; a circular saw blade operatively connected to the driving shaft; first and second mounting plates each secured to the link and including a slanted slot element; and an interconnection including two end holes moveably disposed in the slot elements of the first and second mounting plates respectively, and an intermediate threaded hole secured to the threaded shaft. A rotation of the height adjustment wheel moves the saw blade up or down.

Various aspects of an apparatus are disclosed. In a particular aspect, an apparatus comprising a cylindrical filter, a filter cleaning knob, and a filter cleaning flap is disclosed. Within such embodiment, the filter cleaning knob is configured to rotate the cylindrical filter. The filter cleaning flap is coupled to the cylindrical filter and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated.

A table saw has a base assembly, a table assembly supported by the base assembly, and a saw assembly supported by at least one of the table assembly and the base assembly. The saw assembly includes a saw blade extending through the table assembly. The base assembly has at least one tube connected to the table assembly.

Various safety systems for power tools, and in particular table saws include detection systems for detecting a dangerous condition relative to a blade of the power tool, reaction systems for taking mitigation action in response to detection of a dangerous condition. The safety system may detect, prevent, and/or mitigate a dangerous condition associated with the power tool.
