I saw from a few posts that some of you have these.
Here is a note that the manuel dont cover. The drill chuck needs to be cleaned INSIDE. that means you have to take it apart to do it right .
Be REAL carefull or you will have parts all over the room . DO NOT oil the inside of the chuck just the threads on the back .
They will not cut a releif if the jaws get a build up under the rear.
