SAW HEIGHT ADJUSTMENT MECHANISM HAVING A FLEXIBLE SHAFT
A table saw includes a table assembly having a top surface, a cutting assembly, and an adjustment assembly. The cutting assembly is arranged below the table assembly and is movable relative to the top surface. The adjustment assembly is operably connected to the cutting assembly and includes an input member, an output member, and a flexible shaft. The output member is operably connected to the cutting assembly and is configured such that rotation of the output member causes the cutting assembly to move relative to the table top surface. The flexible shaft has a nonlinear central axis, a first end operably connected to the input member, and a second end operably connected to the output member. The flexible shaft is configured such that rotation of the input member causes rotation of the first and second ends, and rotation of the second end causes rotation of the output member.
Drop arm reset method
A method of resetting a drop arm assembly in a power tool assembly from a first drop arm assembly position whereat a portion of a shaping device mounted on the drop arm assembly does not extend above a workpiece support surface, includes removing a throat plate from a throat plate opening, moving at least a portion of a blade wrench downwardly through the throat plate opening, operably coupling the blade wrench with an arbor shaft of a drop arm assembly, releasing a first latch from engagement with a drop arm frame of the drop arm assembly after removing the throat plate, pulling the coupled blade wrench in an upwardly direction to a second drop arm assembly position whereat the portion of the shaping device extends above a workpiece support surface, and latching the drop arm assembly at the second drop arm assembly position with a second latch.
TRANSPORTABLE MACHINING UNIT
A transportable machining unit with a tool for machining a workpiece, including a box-shaped support structure placed on a support and having a workpiece support plate used to support the workpiece to be machined, and a control device with an operating device arranged on the outside of the support structure. The operating device includes a first rotary wheel and a second rotary wheel, wherein it is possible for a first operating parameter associated with an operation of the tool to be entered into the control device via the first rotary wheel and a second operating parameter associated with the operation of the tool to be entered into the control device via the second rotary wheel.
NON-BINDING FENCE FOR A TABLE SAW
A guide assembly for a saw device includes a pre-load mechanism located at one end and a slide mechanism located at the other end. The slide mechanism establishes two fixed contact points between the guide assembly and a guide rail of the saw device. The pre-load mechanism establishes a third contact point between the guide assembly and another guide rail of the saw device. The guide assembly has an unlocked condition in which the pre-load mechanism continuously generates a first clamping force on the saw device between the third contact point and the two fixed contact points. The first clamping force self-aligns the guide assembly to the saw device and permits slidable adjustment of the guide assembly on the saw device. The guide assembly has a locked condition in which a second clamping force is generated between the contact points and the guide assembly is fixed on the saw device.

Table saw with cutting blade safety feature
A power tool has a base defining a work surface, a rotary cutting blade extending through an opening in the work surface, a drive motor for imparting rotational movement to the cutting blade and a power train coupled between the drive motor and the cutting blade to transmit rotation movement from the drive motor to the cutting blade. A swing arm assembly carries the cutting blade and is pivotably supported on the base at a pivot axis. In one aspect of the present disclosure, the power tool includes a safety system operable in response to an emergency signal that includes a mechanism for stopping the rotation of the cutting blade, whereby the rotational inertia of the cutting blade is converted after the rotation is stopped to pivoting of the swing arm assembly carrying the blade when the rotation of the blade is stopped.
ELECTRICAL CONFIGURATION FOR OBJECT DETECTION SYSTEM IN A SAW
An object detection system in a saw includes an electrically conductive plate positioned at a predetermined distance from the implement, a detection circuit comprising a transformer, and a single cable connecting first terminal and second terminals of the transformer. The single cable includes a first conductor electrically connected to the first terminal of the winding and to the electrically conductive plate, a second conductor electrically connected to the implement, and an electrical insulator positioned between the first conductor and the second conductor.

Table Saw Having a Dual Stage Power Train Assembly
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.
