Abstract: Disclosed is a safety interlock system for restraining certain kinds of movement of a chain saw throttle actuator. The system includes a stop member having an abutment portion for engaging the throttle actuator and a release portion projecting from a surface of the chain saw handgrip in position to be engaged by the hand of an operator gripping the handgrip. The stop member is rotatably mounted on the saw such that the movement of the stop member, as the release portion is depressed into a recess of the handgrip by the operator's hand, causes the abutment portion to swing away from interfering contact with the throttle actuator. Biasing means for the stop member maintain it in an orientation that prevents movement of the throttle actuator until the biasing force is overcome by the pressure of an operator's hand.The stop member can also include a lever portion and a hook portion, the latter engagable with a mating hook on the throttle actuator when that actuator is in an intermediate, or fast idle, position.
