I have been looking at Panelsaws for a while and found a slightly used Powermatic 511 in near perfect conditon.
Brought it to the shop and after spending a couple of hours going over it top to bottom I was thinking this looks more like a floor-model than a used saw.
That said the carriage appeared to have a lot of play, so tweaked a few of the UBolts, and set them with about a 1/16” gap and silicon-sprayed them.
Next I noticed the hefty motor tilts/moves a lot more in the carriage than I thought it would. Apparently Powermatic uses three sheet metal plates: the middle plate is the same size as the cutout and front/back plates are larger and holds the motor in place.
Honestly, I didn’t see this combination of sheet metal and a floppy motor working that well.
The first test cut was a rip, 1/2 mdf, which was pretty good, nice and clean.
Ok next a crosscut, what a total mess, the saw shimmied on the way down, was hard to push, burning and 3/4 of the way down the vertical down cut, popped the circuit breaker.
So what next, do I take the motor of the saw, check/clean/lubricate the plates?
Unless a part broke and fell out somewhere I do not believe anything is broken, missing or bent.
Any ideas about tweaking this saw?

*Blade is a Freud Premier, looks fine.

I don’t know who assembled the saw but there were some strange things going on.
The back of the motor was tilted to the left and the SS rails were told to the right.
The mini riving-knife has to be removed, bent back straight, filled/sanded.
The shimmying was taken care of with dry lube in the weight channel. The weight pulley had to be readjusted.

There was’t any evidence of somebody readjusting the saw parts, the bolts looked like they were never worked on.

One wheel in the middle was stuck, but I was able to free it up with some oil, etc
As far as moving it but it would nice to know that there are two bolts in the down position. Ssoo those make it very difficult to slide, If I had known I would’ve flipped them before moving it. I did not have a lot of manpower,...ugh
