Abstract: Circular saws having a blade that moves relative to a stationary base structure during operative use of the circular saws to cut a workpiece and methods of detecting a kickback condition of such circular saws. The circular saws include a base structure, a user-actuated assembly, an attachment structure, and a controller. The attachment structure is configured to permit constrained relative motion between the base structure and the user-actuated assembly in a motion direction and during operative use of the circular saw to cut the workpiece. A motion sensor is configured to generate a motion signal indicative of motion of the user-actuated assembly along the motion direction. The controller is programmed to initiate a kickback response of the circular saw responsive to the motion signal being indicative of a kickback condition of the circular saw.

Abstract: An extraction apparatus (20) for a cutting machine (10). The extraction apparatus (20) comprises first and second portions (21, 22) rotatable one relative to the other for angular movement between two opposed positions. A slidable coupling (27) defines a fluid flow path (29) for fluid communication between the first and second portions (21, 22) during said angular movement between the two opposed positions, whereby fluid can flow from the interior (45) of the first portion (21) into the second portion (22). The slidable coupling (27) comprises first and second coupling sections (61, 62) slidable one with respect to the other. The second coupling section (62) is hollow to define an open interior (63). The first coupling section (61) defines a duct (65) opening onto the interior (63) of the second coupling section (62), whereby the duct (65) and the interior (63) of the second coupling section (62) cooperate to define the fluid flow path (29).

Abstract: A suspending member, such as a tether strap or the like, may by connected to improve convenience for an operator. The function of the suspending member shall be reliably performed by clearly notifying the user when the connecting part for connecting the suspending member is damaged. A ring-shaped notification member is incorporated in a connecting part for connecting the suspending member. The suspending member is inserted into both of a connecting hole in a connecting part and a notification member so as to be connected. When an end of a handle portion breaks due to long-term use, the notification member is pulled out such that the damage of the connecting part is notified.

Abstract: A power tool that drives rotary cutting element has a retractable guard for the cutting element, and a guard control apparatus allows a user to maintain the guard in a retracted position during operation of the power tool. The guard control apparatus includes an auxiliary handle fastened to the housing of the power tool, and latching elements linked to a spring-biased lever mounted in the auxiliary handle for selectively and temporarily retaining the retractable portion of the guard in a retracted position to enable plunge and other complex cutting operations. Maintaining the retractable portion of the guard in the retracted position during operation of the power tool thereby occupies both hands of the user. This not only helps the user stabilize and accurately control the power tool, but also keeps both of the user's hands safely away from the exposed cutting element in the event of a sudden kickback.

Abstract: A saw assembly includes a drive member, a motor, a housing, and a guard. The drive member is configured to be moved in a repeating pattern. The motor is configured to move the drive member in the repeating pattern. The housing defines an interior space in which the motor is positioned. The guard is secured to the housing and includes a partition. The guard defines (i) a first cutting wheel space positioned on a first side of the partition, and (ii) a second cutting wheel space positioned on an opposite second side of the partition.
