An assembly for immobilizing a chainsaw that includes a platform. The platform having a proximal end and a distal end, and a top surface. The assembly having an upstanding anchor hook and a clamp coupled to the platform for immobilizing the chainsaw. The upstanding anchor hook is configured to receive a front handle of the chainsaw and the clamp is configured to receive a rear handle of the chainsaw, such as to restrict the horizontal and vertical movement of the chainsaw.

An optical operating fluid detector for optical detection of operating fluid for a hand-guided garden, forestry and/or construction machining appliance includes a light source, an operating fluid line and a light receiver. The light source is designed for radiation of rays of light. The operating fluid line is designed for optical interaction of rays of light from the light source with operating fluid in line for the optical detection of operating fluid. The light receiver is designed for differing reception of rays of light from the line in dependence on the presence or the absence of operating fluid in the line. The operating fluid detector has an optical deflecting device. The deflecting device is designed for deflection of rays of light from the light source to the operating fluid line and/or for deflection of rays of light from the line to the light receiver. The operating fluid line is designed for differing diversion of rays of light from the light source in dependence on the presence or the absence of operating fluid in the line for optical detection of operating fluid.

A log lifting device for raising a log into a cutting position includes a cylinder, a handle, and a wedge. The handle is coupled to and extends from the cylinder equally distant from opposing ends of the cylinder. The wedge is coupled to and extends from the cylinder proximate to the handle. The wedge is substantially perpendicular to the handle. The wedge is configured to be positioned beneath a felled log, positioning a user to grasp and pull on the handle to rotate the cylinder to apply a lifting force to the log so that the log is supported upon the handle above a surface. The log thus is positioned to be safely cut by the user using a chain saw, or other log cutting implement.

A tree limb or trunk cutter including a saw assembly, a clamp, and a remote controller. The saw assembly includes a housing, at least one motor disposed within the housing, and a saw bar support rotatably coupled to the housing. The motor is operatively coupled to the saw bar support and configured to rotate the saw bar support about an axis in a first direction and a second direction opposite the first direction. A wireless receiver coupled to the housing is operable to receive commands from a remote controller. The clamp is configured to secure to a limb or trunk of a tree. The housing releasably couples to the clamp. The remote controller is in communication with the wireless receiver and is configured to control a direction of rotation of the saw bar support and to control power provided to a chain drive.

A chainsaw blade storage assembly for storing a chainsaw blade includes a panel that is elongated. A first stop is coupled to the panel wherein the first stop and a chainsaw blade can be positioned around the first stop. A second stop is slidably coupled to the panel and the chainsaw blade can be positioned around the second stop. The second stop is positionable a plurality of distances from the first stop to place tension on the chainsaw blade for storage. A pair of fasteners each extends through the second stop and engages the panel to inhibiting the second stop from moving.

A concrete cutting machine includes a motor, a pivot arm, and a concrete cutting chain assembly. The motor has an output drive, and the pivot arm has an input coupled to the output drive for receiving power from the motor. The arm is configured to pivot relative to the motor, and the pivot arm has a pivot arm output. The concrete cutting chain assembly is supported on the pivot arm and has a power input coupled to the pivot arm output. The chain assembly is configured to be pivotable relative to the pivot arm.

A hand-held power tool (100) may include an electric power source (110), an electric motor (120) selectively coupled to the electric power source (110), a working assembly (130) operably coupled to the electric motor (120) to perform a working function responsive to actuation of the electric motor (120), and a control assembly (140) operably coupled to the electric motor (120) to provide selective control over actuation of the electric motor (120). The control assembly (140) may be configured to provide the selective control based on performance of at least two dissimilar operator actions. The control assembly (140) may include a sensing member (210) and a throttle control member (200). The sensing member (210) may be configured to be operable to an actuated state responsive to an enabling action comprising a first of the two dissimilar operator actions. The throttle control member (200) may be configured to be repeatedly operable responsive to actuation of the throttle control member (200) while the sensing member (210) is in the actuated state. Actuation of the throttle control member (200) may include a second of the two dissimilar operator actions.
