摘要： A battery-powered portable cutting tool such as a chainsaw or hedge trimmer, comprising: a housing (1), a cutting element (2) supported by the housing, an electric motor (6) coupled to the cutting element (2) so as to drive the cutting element (2) to cut, a battery (5) electrically coupled to the motor (6) so as to supply electric current to the motor (6) and a control circuit (9) arranged to control the supply of electric current to the motor (6) from the battery (5), in which the control circuit (9) comprises a main switch (8) operable by a user and an auxiliary switch (10, 11) also operable by a user; in which the control circuit (9) has: an active state in which operation of the main switch (8) by the user allows electric current to flow to the motor (6) so as to cause the cutting element (2) to be driven; and an inactive state in which operation of the main switch (8) does not allow electric current to flow to the motor (6) and so the motor (6) does not drive the cutting element (2); in which operation of the auxiliary switch (10, 11) causes the control circuit (9) to change between the active and inactive states; the auxiliary switch (10, 11) being arranged so. as 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. Typically, the auxiliary switch would determine whether a hook (12) used to suspend the tool was in a position where the tool could be suspended or determine if a chain brake (13) had been applied.

摘要： A method of controlling operation of a hand held power tool may include receiving information indicative of a type of cutting equipment attached to the hand held power tool (100) based on operation of a working assembly (130) in a selected direction of rotation. The working assembly (130) may be configured to be bi-directionally rotatable to perform a cutting function using cutting equipment attachable to the hand held power tool (100). The method may further include determining the type of cutting equipment attached based on the received information, and selectively inserting an operational constraint on the working assembly based on the type of cutting equipment and a selected direction of rotation for the working assembly.
