■ADJUSTMENT OF IDLING SPEED
•The engine idling speed is preadjusted at the factory so that the engine keeps running without moving the drill when releasing the throttle lever to the idling position. However, due to changes in engine conditions, it may be necessary to adjust the idling.
•To increase idling, screw idle adjustment screw in, until preferred speed is obtained. To decrease idling, unscrew idle adjustment screw until preferred speed is obtained.
