A safety mechanism for a hedge trimmer is disclosed. Thumb catches (1032, 1048) together with corresponding locking members are initially biased downwardly relative to corresponding actuators levers (1010, 1014) as a result of which actuation of a motor of the hedge trimmer is prevented. This prevents inadvertent one-handed actuation of the hedge trimmer. In order to actuate the hedge trimmer, the user holds one of the actuators levers the corresponding thumb catch upwardly, which causes movement of the other thumb catch towards its release position to allow pivotable movement of the actuator levers relative to a handle of the hedge trimmer. Movement of one of the actuator levers relative to the handle brings the lever (1018) into engagement with the electrical switch assembly (1008) to actuate the motor of the hedge trimmer. When the actuator levers are released, torsion springs urge the actuator levers and locking members outwardly relative to the handle housing, as a result of which the locking members are urged into a locking position to prevent further actuation of actuator levers until the thumb catches have again been slid out of their locking mechanism.
