Abstract
A power tool having an engine, a throttle control cable, and an electric starter assembly with a user actuated start switch. The start switch has an over-travel actuator section for moving the throttle control cable an over-travel distance. The throttle control cable is connected to the throttle of the engine by an over-travel actuation member. The over-travel actuation member is adapted to move the throttle and, when the control cable is moved the over-travel distance, actuate a compression release system of the engine.
Claims20
A system for starting a power tool comprising:
- a starter assembly;
- and
- a throttle control connected to an engine of the power tool;
- wherein the starter assembly includes an over-travel actuator for moving a portion of the throttle control when the starter assembly is moved towards a start position and the portion includes a control cable that is moved by the starter assembly.
A system for starting an internal combustion engine comprising:
- a starter assembly;
- a compression release system connected to a cylinder of the engine;
- and
- means for automatically moving the compression release system to an open position when the starter assembly is moved to a start position, wherein the means for moving comprises a member at a throttle of the engine adapted to physically contact and move a portion of the compression release system.
A power tool comprising:
- an internal combustion engine with a throttle;
- a compression release system connected to a cylinder of the engine;
- and
- a throttle control system having a throttle lever, a control cable connected between the throttle lever and the throttle, and an over-travel actuation member connected to the throttle,
- wherein the over-travel member is adapted to actuate the compression release system when the throttle is moved by the control cable to a predetermined position.
A system for controlling a power tool comprising:
- an over-travel actuator;
- and
- a throttle control connected to an engine of the power tool, the throttle control having a throttle actuator connected to the engine by a throttle control cable;
- wherein the over-travel actuator is adapted to contact and move the throttle control cable an over-travel distance past a fully open throttle position.
A system for starting a power tool comprising:
- a starter assembly;
- and
- a throttle control connected to an engine of the power tool, wherein the starter assembly includes an actuator for moving a portion of the throttle control when the starter assembly is moved towards a start position;
- and
- a compression release system suitably positioned relative to the throttle control to be actuated by the throttle control.
In a power tool having a motor, a throttle control with a control cable, and an electric starter assembly with a user actuated start switch, the improvement comprising:
- the start switch having an actuator section that directly contacts and moves the control cable.
