tool parts direct or replacement parts. those are two best.

it sounds like a gearing problem simply take it back to where you purchased it and ask for a replacement or a refund

Are the batteries fresh? How about the switch? Is it in the right position? I can't believe the motor has died. Even a dead battery will spin it a little. Check that out and let me know what you find.

It twists off counter clock wise. The best way I have found to remove the chuck is to stick a screw driver into the chuck, tighten the chuck, hold the screw driver in some type of vise and run it all full speed in reverse

Here is the diagram for the drill. I would replace the gearbox and dc control switch. But it may be cheaper to buy a new drill.

18v is one of the newer models, correct? And the drill is new? If so there will be some smell as the motor breaks in. The srmsture is varnished as well as the windind for the commutator. The first few times it get s warm/warm from a heavy load, You will smell it. I would say there is nothing wrong at this point.Do not overload the motor and avoid drilling at low speeds. Use the variable trigger at low speed only for starting a hole. If you are driving screws start the screw,then full trigger driving it in. Good Luck, Ned

The chuck is probably attached to the shaft with a left hand thread. Engage the spindle lock and turn the chuck clockwise to unscrew it.
