After turning two pens and blowing the antler dust off I started to turn a maple burl pen last night and she wouldn't spin. I removed the belt and the motor seemed to turn fine. checked the head and she was stiff the lock was not engauged. I sprayed around the shaft with carb cleaner installed the belt and she took off so. I then sprayed her with a little penitration oil. then read the instructions LOL witch didnt' give any maintenance info on this part. Could this have been that shipping gunk? I'm thinking call the 1-800 # I got it from sears and from issues on a table saw i had I dont want to waste my time dealing with them again on repairs. think i'd rather replace the parts myself is warrenty will let me. Anyone ever delt with jet on warrenty?
