If both functions, hammering & drilling, work correctly on their own but not together your selector knob may be the issue. On the back of the knob is a driver pin that moves the necessary parts to make your tool drill, hammer, or both. If it isn't moving those parts to the exact right place, one or more of the functions may not work. Try moving the selector halfway between positions and see if the gun hammer-drills. If it does you have problems with the selector or drive pin. If it still does not you may have internal parts problems that can only be diagnosed by working on the tool with the knowledge of how it works and how everything inside should be.

Its usually a problem with the selector knob... depress the button fully and turn it passed the selection markings and pull it out to remove it
