A power tool includes a switch moveable between a first position enabling activation of a motor and a second position disabling the motor. The power tool includes a trigger movably coupled to a housing of the power tool between an OFF position and an ON position. The switch moves from the second position to the first position in response to the trigger moving from the OFF position to the ON position. The power tool includes a trigger lock-off pivotably coupled to the housing between a lock position and an unlock position. The trigger lock-off is engageable with the trigger to inhibit movement of the trigger from the OFF position to the ON position when the trigger lock-off is in the lock position. The trigger lock-off allows movement of the trigger from the OFF position to the ON position when the trigger lock-off is in the unlock position.

A handheld power tool (100) comprising at least one orientation sensor (150) is provided. The handheld power tool (100) is operatively connected to a controller (160; 210) and said controller (160; 210) is configured to receive orientation data from the at least one orientation sensor (150), wherein the orientation data comprises information associated with an orientation of at least a portion of the handheld power tool (100) and to determine operational data based on the orientation data, said operational data representing work performed using the handheld power tool (100). The operational data is determined by determining the orientation of the power tool based on the received orientation data from the at least one orientation sensor (150).

A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around 5 which a chain (210) is rotatable. The guide bar (120) includes first and second side plates (400, 410), a core (420) and a tension indicator (240). The first and second side plates (400, 410) each face other and extend away from a housing (110) to a nose. The core (420) is disposed between the first side plate (400) and the second side plate (410). The tension indicator (240) is provided at the core (420) and is visible at at least one of the first side plate 10 (400) or the second side plate (410). The tension indicator (240) is configured to indicate a chain tension based on a position of the guide bar (120).

A hand-guided treatment device has a motor housing, a retaining body arranged in a side region of the motor housing for holding a guide element protruding from the motor housing for a treatment tool which rotates or circulates around the guide element, and an electric drive motor arranged in the motor housing for driving the treatment tool. The drive motor includes a drive shaft with a tool drive region passing through the retaining body, and a rotor held rotationally fixedly on the drive shaft. A lubricant pump drive is coupled to a lubricant pump drive region of the drive shaft for driving a lubricant pump arranged in the motor housing for supplying lubricant to the treatment tool. The lubricant pump drive region and the tool drive region of the drive shaft are arranged on opposite sides of the rotor.

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.
