The screw should be left hand thread and the chuck is normal thread. The 'workshop' way to remove the chuck is to remove the screw (done). If the jaws are still working then clamp a sturdy allen key in it and whack it against a workbench to unscrew the chuck. If holding the drill in the normal position you would stand with the workbench to your left and whack it down on that. If the jaws aren't working then you can grip the body in a vice and use large pipe grips or stiltsons on the chuck. Also check to see if the chuck spindle will accept a thin spanner to hold it, as this is a slightly more caring way to brace the spindle. Then you can can hold the spanner in the vice and use the allen key in the chuck and unscrew it that way.

Replacing the chuck on a drill is simple when you know the trick. I worked at a tool rental center while attending college and learned how to repair many tools. Open the chuck enough to remove the screw that you will see inside the chuck. It will most likely be reverse thread. The chuck is threaded on the shaft so just simply close the chuck on an allen socket and impact off with air or electric impact tool. If you do not have an impact tool close the chuck on-to the largest allen wrench that will fit into the chuck.(with the long part of the allen wrench projecting out) You will need to set the drill into a vise or strap to work-bench, then strike allen with hammer. Most chucks are removed with one quick impact of the hammer, counter clockwise. Do not squeese the drill too tightly with vise, we used a piece of leather to protect the drill. Good luck. Enjoy

I just looked at a breakdown for this tool and it is not that clear. But to get an owners manual you can go to Searspartsdirect.com and type in your model number and look at the same schematici I did and also order a manual for about 7.50. Usually though on a drill press like that it would be a morse taper. Do you see a slot cut thru the spindle on both sides, if so there should be a tapered key that came with the unit. In that case what you would need to do it put the key in the slot and tap it with a hammer to remove the adaptor and chuck. Let me know if I can help further

If it's anything like their other drills, there is a safety screw with left-hand threads inside chuck.

1. Uncscrew screw CLOCKWISE until loose.
   
2. Then insert the short arm of a 3/8" hex wrench and tighten.
   
3. Strike long arm of wrench sharply counter-clockwise and chuck should loosen to unthread from spindle.

You need to open the chuck and remove the bolt from the bottom of it[usually a #2 phillips].The next step is to insert a 5/16 allen wrench into the chuck and tighten the chuck.Hold the drill with the chuck facing away from you then strike the allen wrench with a hammer on the right side[so it goes down] and now you will be able to remove it by hand,good luck.
