My Bosch CSB 650-2RE works fine when drilling horizontally, but as soon as it goes vertical the power goes off, even though switch is still depressed

You probably have a loose wire at one on the connections inside the unit. Open it up and have a look at all the connections, pay special attention to any push in connections as they tend to get loose over time.

We need to replace the chuck on our Bosch corded drill 1005VSR. We need detailed instructions on how to remove the chuck . Also, how can we order a new chuck?

Open the chuck wide open. In the center is a retaining screw, they usually have left hand threads. Remove the screw. Take an allen wrench 1/4" to 3/8" in size and fasten the short side tightly in the chuck. The chucks are usually right hand thread, so take a small hammer and strike the allen wrench to turn the chuck to the left to loosen it. Once you have the chuck off, verify the thread size of the drill motor shaft, then go to McMaster-Carr and choose the one you need.

you can distinguish it either of these by:
1. hard to push.
2. can smell a little bit smoke from the switch due to
loosen contact.
3. Can not feel or hear a "Click" when pushing it,.
4. The drill will not totally turn.
