  • Patent number: 9460869
    Abstract: The invention relates to an electrically powered hand tool which comprises a device for providing tactile feedback to an operator of the tool. The tool further comprises a user-operated trigger for activating the working member of the tool. The tactile feedback provided by the tool alerts the operator about the activation status of the tool. More specifically, the operator is provided with an indication that the power to the tool is ON. The tactile feedback is provided at least from the time when the power to the tool is turned ON to the point in time when the trigger is pulled to activate the working member of the tool.

  • Publication number: 20130025135
    Abstract: A hedge trimmer (1) comprises an electric motor (3) and at least two cutting blades (5,6), each blade comprising at least one row of teeth with the motor being connected to at least one of the blades so that rotation of the motor (4) produces a movement of at least one of the blades relative to the other, a first user operable switch (10) for operation of the hedge trimmer blades and a second user operable switch (11) which enables a user to select between at least two operating modes of the hedge trimmer, the two modes comprising a hedge trimming mode in which operation of the first user operable switch causes a reciprocal motion of the at least one blade, and a secateur mode in which operation of the switch causes a single cutting cycle to be performed. A two ratio gearbox may be provided to enable the blades to move at a lower speed and with higher torque when in the secateur mode compared with the hedge trimming mode.
