How do I lock drill bits on to my Bosch power tools?

Question:

Inherited a set of Bosch power tools from my dad, I can't seem to lock drill bits on to the tool. Any clues?

Answer:

If it's a regular drill they all have you covered, BUT if its a hammer drill then it may have a different kind of chuck. these are smaller, no teeth, and probably smooth and smaller than the normal chuck, the drill bit has a larger section about 1 to 1 1/2 inches long this section has three little pockets located in the sides of this swollen part. You just insert this into the chuck and pull the chuck back toward the body of the drill. the drill bit becomes locked in place to remove it just reverse the process. these drills usually have three kinds of functions, there is a switch on the side that changes the function. It will drill like a conventional drill, or the bit will move in and out in a hammering motion, or it will do both at the same time hence the name hammer drill. It is for drilling holes in masonry, You can even get a chisel for breaking up concrete.

Bosch makes a great tool line, too bad they are moving all their operation to China.......
