after reading that thread, i tried cleaning up the clutch some. mine would hesitate, chatter/vibrate, and sometimes stop turning while drilling. i took the clutch mechanism apart last night. i didn't find any grease or anything in there. it appeared to be nice and dry, but i took some carb cleaner and gave it a good once over. i did get some black residue on the rag, but nothing major. i hope this works. it'll cut holes, but not like it should. and it's only a year old. if this doesn't help the problem, i don't know what to do next. i'd hate to take it to a shop, don't really have the cash for that. anybody got any other suggestions or recommendations? thanks...
