I recently bought a used PCB222TS table saw at a garage sale for next to nothing. After spending some time cleaning it up. I have found a problem that I can quite grasp the cause of. With the blade all the way up I was able to true the saw blade and align it in the center of the throat plate by loosening the 4 cap screws that hold the motor assembly under the front and back edges of the table.

The problem arises however as I lower the blade the front of the blade moves to the left. The farther down the blade the more it moves until it is nearly hitting the the left side of the throat plate when bottoming out, almost 1/4” . The back of the blade is still pretty well centered in the throat. I don’t see anyway to adjust my way out of this so I assume that something is either bent (the “body” item #130) or worn out (the slider Item #128) or ??

Any one been down this road and can share the cure?

I don’t know your saw but you should align your blade with the miter track and not the throat opening. Different saws have the blade center, right and left That does not make any difference if the blade is aligned with one side the miter track.

Did you follow the alignment procedures in the manual?

Here’s manual if you don’t have it. Start on page 20.

Ocean & WhyMe
I used the miter track to do the alignment per the manual. I only referenced the throat because it is obvious and easy to see the problem there. After aligning with the blade all the way up using the miter tracks, and then measuring to miter track with the blade nearly all the way down, the front of the blade has moved/skewed 1/4” to the left. You can see the front of the blade become gradually misaligned to the left as it is cranked down. i.e half way down ~1/8” out of true, all the way down ~1/4” out of true. The rear of the blade does not move perceptibly as the blade is cranked down. I suspect that the “body”., item #130 in the parts list was bent at some point. If I had to guess I would bet the saw was dropped at some point. but there are NO other obvious signs of damage.

I have a couple of projects ( making storm shutters for the cabin) that using it in simple cross cut and rip modes will be fine with the blade up, but eventually I want to be able to do dados and that requires the blade to be down. After I get these projects out of the way I have no problem tearing the saw down especially If I can clearly see the problem when I get there but I would hate to spend $50 on a new “body” and that not be the problem. That is why I am hoping that someone has seen the problem before and says “Oh yeah just put a pipe wrench on the lower front edge of the do-hickey and bend that till it is back in alignment with the blade all the way down” .... 8^)

It sounds like there is something is broken or bent below the table. Possible one or both trunniones that allow the arbor/cradle and blade to tilt. Without looking carefully at all the components, that is all I have. Maybe someone who also has this saw can chime in.
