If you go to Boschtools.com you will find the manual you are looking for. They are all on the web site.

Are you sure you are locking it in right? The STS locking mechanism on most of these tools is sometimes hard to do, you have to sometimes really push hard while turning it until you hear an audible "click" to know it is seated.

there is a selector knob on the side that controls the tool functions for drill only/hammer with drill/ and hammer only. make sure it is in the proper setting. If it still doesn't rotate then you have a gear or a broken selector. If no hammer then you have worn o rings or a stuck ram. try the selector first and if still no change please be more specific if no hammer at all, or no rotation even when selector moved.

Rotate the selector to the 4 to 5 oclock position, or the 7-8 oclock postion, push the red button in all the way with a screw driver and pull the knob out. Certain model hammers you have to rotate to a slightly different position to remove the selector, you will have to try one, if it doesn't work try the other.
