I stopped at a fellow LJ and she had a 10 Jet table saw with the blade out of alignment with the fence and table slots by 1/8”. The tilt mechanism went about 15 degrees and bound up tight too.

I called Jet technical service (1-800-274-6846) and they were very helpful. They sent me an E mail note with instructions to align the blade. Initially when we talked, I thought I had to loosen the trunnion bolts to move the blade into alignment.
The instruction said to get a flat 6×9” board and lay it on the rods under the blade to see if the board rocked. That would mean the rods are not in plane or parallel as they say. Well it rocked a lot. To get them in plane, you have to loosen the large nuts on the back of the rods and move the motor left or right to bring them back in plane. I did that easily and checked the blade. It was back in perfect alignment. I tightened the nuts and tried it out. It cut very free and the tilt mechanism also moved very freely all the way to 45 degrees. I did not have to touch the trunnion bolts.

I offer this to other Jet table saw owners in case you should encounter this problem. I did not previously use the saw so I had no idea how it got into that condition. The LJ now goes by the handle of Bladebender!!!!!!!!

Thanks for providing the info (however long ago it may have been). This solved my maddening alignment issues, too.

FYI, when viewing the saw from behind, loosen the nuts by turning CLOCKWISE.

I have this saw and it’s been a constant headache. Trust me, those trunnion bolts are a PAIN in the you know what. The front ones are inaccessible by normal means. The manual doesn’t mention the board thing but after realigning it a few I did mess with those bolts.

In any case the bolts are not fixed to the table like some have said, you can remove them and I’m in the process of making my own so readjustment is easier.

I’ll have to try the board thing, just to bad they didn’t put it in the manual. I’ve pretty much got it tore down at this point so everything has to be redone anyway now.

Hi Ray, this process I found to fix the alignment was pretty simple. But, she does not do any big cutting on that saw and I was concerned that it went out that easily. I advised her to sell the saw and she did. I am not a Jet fan. I had one of their metal lathes and after I saw the poor design of that machine, I peddled it real fast. I don’t have patience for machines that give me problems.
I hope you get your problems solved. That board to check alignment did the trick for her and the nuts were easy to get to but that saw was buried in a big table with a box around the motor.. I had to tear the table all apart to get to heart of the saw.

Good luck….........Jim

Jim,

Thanks for the info. I just purchased one of these, and it had to be adjusted. This fixed it perfectly.

Thank you. I spent a good half day messing with my trunions. looking at countless youtube videos. After stumbling onto this i grabbed a 1×6 peice of scrap wood and it took all the play I had out and brought me into 20 thou. Then I adjusted the rear trunions to to bring it in. Only took about 15 min. thank you again.
