Abstract
An outdoor power tool may include an engine, a carburetor configured to provide a fuel and air mixture to the engine based on operation of a throttle assembly, a selector and a throttle release actuator. The selector may be operably coupled to the throttle assembly to control a position of the throttle assembly in a selected one of a plurality of throttle positions. One of the throttle positions may be an idle position and each of the other throttle positions may be selectable by an operator via manual positioning of the selector. The throttle release actuator may be configured to return the selector from any one of the throttle positions to the idle position responsive to operator actuation of the throttle release actuator.
Claims18
An outdoor power tool comprising:
- an engine;
- a carburetor configured to provide a fuel and air mixture to the engine based on operation of a throttle assembly;
- a selector operably coupled to the throttle assembly to control a position of the throttle assembly in a selected one of a plurality of throttle positions, one of the throttle positions being an idle position and each of the other throttle positions being selectable by an operator via manual positioning of the selector;
- and
- a throttle release actuator configured to return the selector from any one of the throttle positions to the idle position responsive to operator actuation of the throttle release actuator.
A method of assembling a throttle release actuator, the method comprising:
- providing a support assembly proximate to a shaft of a throttle assembly, the shaft operably coupling a selector to a throttle valve of the throttle assembly for selection of a position of the throttle valve based on manual positioning of the selector in a selected one of a plurality of throttle positions;
- providing a biasing assembly into a portion of the selector, the biasing assembly configured to return the selector to an idle position from any one of the throttle positions responsive to operation of the throttle release actuator;
- inserting the selector into a window defined in a cap structure of the throttle release actuator while compressing the biasing assembly to enable the biasing assembly to fit within the window, the window enabling rotation of the selector about an axis defined by the shaft to the throttle positions;
- and
- attaching the cap structure to the support assembly.
