Hand-guided power tool with a control device

A handheld work apparatus has a combustion engine with a cylinder. A removable cover is fixed via a closure. The closure includes a tensioning element rotatable about a rotational axis and, in the locked position of the closure, is supported on a tension contour. The closure has a damping element. The damping element is held on a section of the cylinder in the axial direction of the rotational axis. During rotation from unlocked into locked position, the tensioning element is moved by the tension contour in the axial direction of the rotational axis. In the locked position of the closure, the tensioning element clamps the section of the cylinder in the axial direction of the rotational axis between a first abutment and a second abutment of the damping element. In the unlocked position of the closure, the tensioning element is held on the damping element on the cylinder.

Handheld work apparatus

A hand-guided power tool has a power tool housing and an internal combustion engine arranged in the power tool housing and configured to drive a tool member of the power tool. A fuel tank and at least one electric component are provided. A control device that is an electronic control unit is connected to the at least one electric component of the power tool and controls the at least one electric component. The power tool has a top face which, when parking the power tool in a usual parking position on a flat horizontal support surface, is facing upwardly. The electronic control unit is positioned laterally adjacent to the fuel tank device, when viewing the power tool in the usual parking position.

A handheld work apparatus has a motor unit comprising a drive motor. The drive motor drives a tool of the work apparatus, for example a saw chain. The apparatus has a grip unit with a handle that is vibrationally decoupled from the motor unit via an antivibration element. The antivibration element is connected to a first component of the grip unit via a holding device and a second component of the motor unit via a holding element. Arranged in the connection of the first component to the second component through the antivibration element is a predetermined breaking point formed in a third component that is replaceable independently of the first component and the second component. The strength of the connection of the first component to the second component through the antivibration element is lowest at this predetermined breaking point.

A hand-held work implement comprises a housing, at least one tool and a combustion engine for driving the tool. The combustion engine has a cylinder and has a piston which drives a crankshaft in rotation about an axis of rotation. The crankshaft drives a fan impeller. The work implement has a handle unit with a handle bar and has an engine unit, these being connected to one another via anti-vibration elements. The combustion engine has a transverse plane which encompasses the cylinder longitudinal axis and which runs parallel to the axis of rotation of the crankshaft. The transverse plane divides the work implement into a front region, in which a section of the tool that projects out of the housing is arranged, and a rear region. The fixing of the anti-vibration element to the cylinder is realized in the front region.

Hand-held work implement

A hand-held power tool has an internal combustion engine provided with a throttle trigger adjustable between an idle position and a full throttle position. The engine has an operating mode selector adjustable between an operating position and a start position. In an intake passage of the engine, a throttle element is arranged that is in a throttling position when the operating mode selector is in the start position. The throttle element is secured in the throttling position by a locking action. The locking action is released when the throttle trigger is moved from the idle position toward the full throttle position. A restoring element is coupled permanently to the position of the throttle trigger. The restoring element, when the throttle trigger is moved for releasing the locking action, acts on the operating mode selector and restores the operating mode selector from the start position into the operating position.
