delta model 36-680 table saw trunion bolts

I need to align my saw blade to be parallel to the mitre slots and am not certain which are the front trunion bolts. My saw has two hex nuts (marked #36 on the spare parts diagram) which are accessible on the top of the cast iron table ... are these the trunion bolts or are they for some other purpose (if so what?)
thanks in advance

I have a different model, but the two hex nuts in my table are for the angle stops. Check the manual if you're not sure.

Need more information. Make, model and year, and the trunnions will follow. Tom

The trunion bolts are under the top. You have to go in from below. They connect the trunions to the bottom side of the table top. There are two front and two back bolts. You can't miss em.

One adjusts the stop for your blade to be at 90 degrees to the top and the other sets the 45 degree stop.

look at the attached drawing. This will give you a good idea for almost all of that series of Delta saw.

Parts 267 and 214 are the trunnion brackets. The bolts are 217 and 265. The holes in the two trunnion brackets should be slightly enlarged. If you loosen the four bolts just a turn or two, you should be able to tap the brackets and the trunnion assembly (item 207) sideways
To measure the alignment, refer to a single tooth on your blade. Mark it with a marker. Rotate it to the front of the saw and measure it to the mitre slot. Rotate it to the back and do it again. Keep adjusting until that measurement is the same.
Do not measure across the whole face of the blade, as the blade or the arbor (202) may be out. IF the arbor is out, that is a whole different fix.
You only need to barely move the brackets one way or the other sideways to change the alignment ALOT. Two important notes: 1) do not really wiggle everything around as the trunnion will fall out of the brackets and then you will have to remount everything. 2) do not overtighten the bolts when you are done. The top will crack.
Shouldn't take you more then 30 minutes to align the blade to the slots.

In addition to advice already given, if your unit has flat washers take the front screws out one at a time and replace the washers. Reason is, the clearance holes are larger than usual to give maximum adjustment, and the washers form into the hole, become conical and have memory back to the old position even after you have adjusted to the new position. Will often slide back to the old position. Also can happen with washer face screws, I'd replace them if your adjustment is significant. Keep in mind, you should only have to do this once if your saw doesn't take a significant hit.

Standing at the operator side of the saw, the front trunion bolts are located in the far right and far left sides of the saw under the top.
You will find that they are damn near impossible to see or reach with a wrench of any size.
Be prepared to stand on your head while making ajustments.
The "back trunion" bolts are very easy to see and reach from the operator side.
Good luck....
PS: You will need a VERY long 3/8" extension or two.
