Abstract
A string trimmer with a control system for electric start, throttling, compression release, and engine kill control. An interlock is provided for preventing a start switch from being actuated unless the throttle trigger is fully actuated to a throttle fully open position. An idle setting system and engine kill button is provided at a control section at the throttle trigger. A single control cable is used for throttling, actuation of a compression release system at the engine, and stopping the operation of the engine.
