摘要： The present invention concerns a handheld working tool comprising a motor part (10), a handle part (20) comprising a handle grip (21), and at least one first type antivibration element (30) arranged between said motor part (10) and said handle part (20), and which element (30) is adapted to isolate the handle part (20) from vibrations in the motor part (10). The working tool (1) is characterized in that it further comprises at least one second type antivibration element (40) arranged adjacent to the first type antivibration element (30). The at least one second type antivibration element (40) is adapted to, when in an active state, prevent vibrations in the motor part (10) from being transferred to the handle grip (21). The second antivibration element (40) is in the active state when the handle grip (21) is loaded during operation of the working tool (1). The working tool is further characterized in that a longitudinal axis (L1) of the second type antivibration element (40) is separated from a longitudinal axis (L2) of the first type antivibration element (30).

摘要： A battery-powered portable cutting tool includes a housing, a cutting element, an electric motor to drive the cutting element to cut, a battery to supply electric current to the motor and a control circuit to control the supply of electric current to the motor from the battery. The control circuit may include a main switch and an auxiliary switch. The control circuit may have an active state in which the main switch allows electric current to flow to the motor and an inactive state in which the main switch does not allow electric current to flow to the motor. The operation of the auxiliary switch causes the control circuit to change between the active and inactive states. The auxiliary switch is arranged to determine whether the tool is in an inappropriate state to be used and, if so, cause the control circuit to change to the inactive state.

摘要： A chainsaw (1) comprises an internal combustion engine (3) having a cylinder (4) with a piston (5) connected to a crankshaft (6). The piston (5) has an upper surface at a distance D from the central axis of the crankshaft (6) measured along the longitudinal axis defined by the cylinder (4), when the piston (5) is in its top dead centre. The chainsaw (1) is further provided with a front handle (7), which central axis is disposed at a distance B from the central axis of the crank shaft (6) along an axis substantially perpendicular to a horizontal plane (13), the horizontal plane (13) being defined as the plane on which the chainsaw (1) may rest in an upright position when not operated. The chainsaw (1) also includes a throttle lever (9), which rear end is disposed at a distance C from the central axis of the crankshaft (6) along an axis substantially parallel to the horizontal plane (13). The cylinder (4) is inclined backwards, such that the angle between the longitudinal axis defined by the cylinder (4) and an axis perpendicular to the horizontal plane (13) is between 5 and 45° , and the chainsaw (1) further having a basic design such that the relation B/D is less than or equal to 1.7, so as to provide a low front handle (7).
