Torque adjustment ring is stuck on one setting.

My Craftsman drill, model 315.114852, "Torque Adjustment Ring" is stuck and I can't turn it to select different torque settings. How can I fix this so I can use different settings? Thanks.

Try using canned air while tapping the torque adjusting ring with a rubber mallet around the ring. Dirt may have entered and plugged the locking/unlocking mechanism from operating freely. You might have to try using WD-40 lube.
