A battery waking circuit and a battery leakage circuit are provided. The battery waking circuit includes a first battery pack and a second battery pack connected in series and a first switch connected to the first battery pack along a first current path. An electronic controller coupled to and controlling the first witch is configured to detect a trigger actuation and close the first switch based on detecting the trigger actuation to draw a wake-up current on the first current path from the first battery pack. The electronic controller is also configured to control a motor to draw a load current along a second current path after the first battery pack is woken up. The battery leakage circuit also includes a switch connected in series with the capacitor and a trigger switch controlling the switch such that the switch prevents a flow of leakage current through the capacitor when the trigger is not actuated.

Embodiments of the present disclosure provide surface treatment tools, methodologies, and/or treated turbomachine components. A surface treatment tool according to the present disclosure can include a lathe assembly having a lathe chuck for receiving a component thereon, wherein the lathe chuck rotates the component about a first axis of rotation, and wherein the component includes an exposed axial target surface; and a sander or burnishing tool coupled to the lathe assembly and including a sanding or burnishing surface thereon, coupled to a drive system, wherein the sanding or burnishing surface is oriented along a second axis substantially non-parallel with the first axis of rotation, such that the sanding or burnishing surface selectively contacts the target surface of the component to yield a polished target surface.

A circular saw with a moving mechanism includes a base, a moving unit and a cutting unit. The base has a worktable which has a front side and an opposite rear side, and defines a first plane which extends substantially horizontally from the rear side toward the front side. The moving unit is disposed above the worktable and includes a supporting frame disposed on the worktable. A first sliding shaft and a second sliding shaft are located parallel to each other and disposed at an interval relative to each other on the supporting frame. A moving member is also disposed on the first and second sliding shafts. A second plane is defined as a plane extending through an axis of the first sliding shaft and an axis of the second sliding shaft. Moreover, an included angle is formed between the first plane and the second plane and ranges from greater than zero degrees to smaller than 90 degrees. The cutting unit is pivotally mounted on the moving member and is linearly movable along the worktable in a horizontal direction.

A table saw hold-down device comprising a straight edge located on a horizontal planar surface, wherein the horizontal planar surface includes a table saw. The straight edge includes a flat surface against which an item is placed when being cut by the table saw, and wherein the flat surface is perpendicular to the horizontal planar surface. Two or more wheels are movably coupled to the straight edge and are configured such that when said item is placed against the flat surface of the straight edge when being cut, and the wheels contact said item, the wheels rotate to accommodate movement of said item along the straight edge. At least one spring loaded mechanism coupled to the wheels is configured for moving the wheels down such that when said item is placed against the straight edge when being cut, the spring loaded mechanism pushes the wheels against said item.

An apparatus for transverse cutting of a web has a frame straddling the web path, a side frame on each side of the web path and an upper frame between the two side frames, a circular saw blade suspended in a pendulum arm pivotably connected to the upper frame, a swinging drive for controlling the swinging movement of the saw blade, wherein the pendulum arm is pivotably mounted in a vertically movable sub-frame of the upper frame, and the vertical movement of the sub-frame relative to the upper frame is managed by a lifting drive that is coordinated with the swinging drive. Also disclosed is a method for transverse cutting a web.
