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.

A lubrication system for a saw may include a lubricator that is mechanically linked to a traveling arm of a saw, such as an up-cut saw. Movement of the saw blade through a first path may result automatically in movement of the lubricator through a second path transverse to the first path. This coupled movement may result in a relatively consistent distance between the lubricator and the periphery of the saw blade, especially as compared with a stationary lubricator.

The present invention pertains to the technical field of shields, and in particular, relates to a stage dedusting shield for a dust-free table saw, comprising: a shield assembly and a dust suction cover assembly; wherein the dust suction cover assembly is mounted between a follower board and a rear portion of a saw blade and is fixed by the follower board and a rear rocker arm. The dust suction cover assembly comprises a dust suction cover and a rear rocker arm sleeved onto the exterior of the dust suction cover, wherein the dust suction cover and the rear rocker arm are movably connected to a dust suction cover torsion spring via a dust suction cover rotary pin.

A table saw includes a base assembly, a table assembly supported by the base assembly, and a saw assembly supported by the base assembly. The saw assembly has a motor having a motor output shaft and a power train assembly. The motor is configured to rotate the motor output shaft at a first rotational speed. The power train assembly includes an intermediate shaft, a first gear stage, an arbor shaft, and a second gear stage. The first gear stage is configured to transmit rotation of the motor output shaft at the first rotational speed to rotation of the intermediate shaft at a second rotational speed, which is less than the first rotational speed. The second gear stage is configured to transmit rotation of the intermediate shaft at the second rotational speed to rotation of the arbor shaft at a third rotational speed, which is greater than the second rotational speed.

A table saw including a table, a saw unit, a storage mount bracket, and a blade guard assembly. The saw unit includes a saw blade and a riving knife. The saw blade is extendable through a slot in the table. The riving knife is positioned behind the saw blade and has a first mating interface. The storage mount bracket has a second mating interface complimentary to the first mating interface. The blade guard assembly is attachable to the first mating interface of the riving knife to cover at least a portion of the saw blade. The blade guard assembly is additionally attachable with the second mating interface to attach the blade guard assembly to the storage mount bracket when the blade guard assembly is removed from the riving knife.

Blade tilt mechanisms for table saws are disclosed. The disclosed tilt mechanisms provide easy and intuitive operation. They also provide auto-locking so that a user simply releases a component to lock the blade at a specific angle. The tilt mechanisms also provide defined incremental steps for the tilt of the blade and the steps are typically spaced at 1-degree intervals.
