I took my riving knife off a few days ago and put it back on. When I put it back on I could nto get the riving knife adjustment handle (or whatever it is called) back in the same position.

Look at pic 1. Pic one shows the riving knife locked. I took this pic at Lowes on the 36-725 they had set up. This is also how my adjustment handle looked before I took my knife off. Notice how the handle is pointed up and the grooves at the base line up / locked in with each other.

Pic 1

After removing my knife and reinstalling it I can not get the knife adjustment handle back in the up position. Notice in pic 2 how the handle is not pointed up and the grooves at the base are not lined up and “locked” in with each other.

Pic 2

Even though the handle is not locked in the up position like it originally was my knife is still lined up with the blade and doesn’t move at all but I’m afraid that since the grooves at the base aren’t lined up and locked in with each other that the handle could works its way loose and make my knife no longer lined up with the blade. I can’t pull the handle up all the way to line up the grooves. What am I doing wrong?

Thanks,

I’ve never messed with it, but does that nut need to be loosened to get the handle in place then tightened?

Not that I am aware. Initially I was able to move the handle just by moving it to the side then up and down. Messed with the one at Lowes and it was the same way.

I have the same saw and I am not sure I understand your question completely.

When the handle is in the up position (as in Picture 1), that is the “unlocked” position so you can remove the the knife.

After the knife is installed, Picture 2 is the locked position. It operates as a cam and is not supposed to be in the cut-away on the lever.

Here is the page from the operators manual:

If this doesn’t help, ask your question differently.

I’m with Gart. Your Pic 1 seems to show the handle in unlocked position so RK can be removed. To lock the RK, you press the handle down as shown in Pic 2 for “running” the saw.

so in my pic #2 you can see the base of the lever is not locked into the grooves. that the correct lock position? i guess i’m confused because when i first went to remove the knife it was in the up position so i assumed that was locked.

Maybe we’re not using same definition of locked/unlocked. To me, locked (handle down like your Pic 2) indicates that the RK is “locked” in place, not the handle, and will not move when making a cut. Unlocked (handle up like your Pic 1) indicates that the RK is not in a safe position to make a cut and that it can be removed/adjusted/replaced as needed (handle up).

Your last post sounds like you are defining locked based on the cams of handle position, not ability of the RK to move.

Is your handle down (what I call the locked) and will not move to the up position (what I call unlocked)? If so, I’ve not had that occur.

The correct position to run the saw is with handle down like Pic 2…

it just looks like the lever should go down a little further and settle into that indent in pic 2 to be completely secure

No, it is supposed to be as shown in pic 2 when locked. If you push down on it until tight and you can’t move RK from side to side you are good. If you push down and it goes past the lobs on the cam locks and back to the position where the indents line up, it would release all pressure on the RK and the RK would be loose again. Then I think you would need to tighten the nut knotscott pointed out.

On my 36-725 if the handle is pointed up when putting the blade fully up the handle hits the bottom of the blade throat insert before the blade reaches full height. The riving knife tension handle needs to be in the down position to hold the riving knife tight and to not hit the bottom of the blade throat insert.
