I’m the proud owner of a new Delta 36-725 it’s the first table saw that I’ve owned and I’m having a heck of a time getting the riving knife aligned with the blade. I know this a somewhat popular saw and that you fine folks have been knowledgeable and helpful in the past.

There are 4 screws that are used to adjust the riving knife to bring it into the same plane as the blade but I just can’t seem to get the hang of how they are supposed to be used. I feel like every time I start to get it lined up in one direction it throws it out of alignment in another. I’m hoping that you guys can talk me through a strategy to get from where I’m at to where I need to be. The images below were all taken from the rear of the saw so the adjustment screws on the right in the images and the fence is off to the left.

The blade is currently perpendicular to the table.

If anyone wants to take a look at the manual the relevant portion is on page 28 here.

Any ideas would be greatly appreciated.

Did not need to adjust mine but, if I remember right, you should just barely loosen the screws that secure the riving knife. If you get them too loose, it can be lose alignment as you tighten them. I think same thing applied to screws when aligning blade to miter slot. So, I may be crossing up the two issues.

Not to insult your intelligence, but did you make sure there’s no dust stuck between the knife and the holder? Mine is slightly out of alignment at the moment as I need to blow the dust out of the area.
After reading the instructions, I think it’s a bit off. There is no picture of where Set Screw D is. I looked on mine and I’m guessing the two socket screws are B & C, and the two set screws to the right are A or maybe the lone set screw not labeled is D; I can’t tell. I’d say after you make sure there’s no dust, get it in horizontal alignment first, lock the set screw closest to A and then adjust D, if that’s what actually does adjust the vertial, and then lock down on the 2nd set screw. See if that helps.

I do need some help though please. I bought one from a wholesale company which seems to be a mistake. I tried the more complex blade alignment procedure due to the fact that the blade was a 1/4 of an inch off (so loosened both set screws and the other allens to try and shift)!! I was able to get it within 1/16 of an inch which is still to far off. Also it didn’t come with a throat plate which should have been a red flag. I ordered the Delta zero clearance and it seems like the blade is too far to the left for the plate to even sit down in the slot. Any ideas if the whole motor could have shifted? I looks like only a few pieces have been ran through it and the whole machine looks brand new so I figured for 200 bucks I would chance it.
Thank you,

Have your say...
