摘要： A manually guided implement, especially a brush cutter, comprising a guide tube with a guide motor at one end and a tool head that carries a rotatably drivable tool at the opposite end. A handle is disposed on a securement mechanism, and a handle carrier is disposed between the securement mechanism and the guide tube. The handle carrier is fixed in position on the guide tube along a short range relative to the longitudinal direction of the guide tube. The securement mechanism is adjustably held on the handle carrier such that the position of the securement mechanism relative to the longitudinal direction is adjustable.

摘要： The invention is directed to a composite crankshaft for a two-stroke engine for portable handheld work tools including chain saws, cutoff machines and the like. In composite crankshafts, a crank pin is connected to a crank web by a press fit wherein the inner diameter of the press-fit bore is expanded toward its axial end in order to reduce stress peaks. In this way, the press-fit surface has a radial spacing with respect to the center longitudinal axis of the press fit which changes. The press fit of the crankshaft of the invention is so configured that the radial distance of the press-fit surface changes in dependence upon the axial spacing to the axial center of the press fit according to an exponential function having the equation f(x)=a.multidot.e.sup.b.multidot.x wherein (a) and (b) are pregiven constants, (x) is the axial spacing and f(x) is the radial spacing. In the composite crankshaft of the invention, stress fields produced by the press fit are substantially uniform and the load on the crankshaft is reduced.

摘要： A motor-driven chain saw essentially includes a housing having a rear handle and a front handle and a drive unit attached to the housing. A guide bar for accommodating the saw chain for movement thereon is attached to the drive unit. The housing has an extension arm on the underside of the chain saw which extends to the front; the drive unit is seated on this arm and the front handle is attached to the front end of the arm. To increase torsional and bending strength, the extension arm has an S-shaped profile when viewed in cross section. The S-shaped profile has a substantially rectangular configuration and includes lower, middle and upper parts that are parallel to one another and are interconnected by two flanks. The flanks are located in planes that are parallel to the guide bar.
