I’ve got a problem getting my rip fence to align with scale on the front rail. The manual says to place the rip fence against the blade as shown in Fig. 31 (just adding this in case anyone has this and can see what I’m talking about). Doing this is supposed to line up the mark on the right side of the rip fence indicator with “0” on the scale. Mine is off by 1/4”. The instructions say that to fix this you should loosen the rail a bit and can then nudge the rail to align. There’s no way I’m getting that rail to move 1/4”. There’s no play in it. Besides, this would then cause the left side indicator of the rip fence to be off by at least this much.

I have a photo to show this but am having trouble trying to load it.

I would really appreciate any advice on how to get this to line up properly.

I had mine so close I could align it by moving the indicator slightly, but noticed that after setting it perfectly it wouldn’t stay and in a week I was sliding the indicator the other way. I gave up trying to get it right and use it as a guide, then use a ruler from the blade edge to get the exact measure.

So like with most things on this saw I can’t trust it and have to carefully check the fence and blade alignment after any change.

It will be replaced by a sawstop as soon as I can get rid of it.

Have you adjusted the sight glass? See Fig.52.

I just did this last month. After it was all done I saw the scale off by 3/8” and couldn’t adjust it in with the sight glass. I had to loosen all the screws that hold the fence rail to the table top- both the cast iron and steel extensions. Then the rail is free to slide many inches in each direction as the bolt heads are in the extruded aluminum. Set the sight glass back to the middle first, then tighten the rail back in the ballpark. Then I re-leveled the rails with a couple playing cards under the fence, Now it glides like silk.

Thanks everyone for the responses. TomM, I will follow your explanation seeing as only adjusting the sight glass doesn’t get anywhere close to adjusting for 1/4” of misalignment.

Have your say...
