I don’t really understand this, but somehow my PC compound miter saw (3802L) seems to be cutting trapezoids. The fence is fixed so that can’t be it (I think) and the table is locked down at 0. Maybe this is a stupid noobie mistake but I have used it for 6 years without this ever happening and this morning it won’t give me true cuts. What do I do now? Thanks in advance for your help, Gus

This may sound dumb, but have you checked the blade? I have had a saw cut bad suddenly, I had to tighten the blade. Just thinking.

Did you check the fence and blade for square? If not, make sure you use a square that you know is a true square. It may just need a small adjustment which you should be able to find in your manual. It is not uncommon for MS to need adjustments from time to time.

to check for square ,
use a straight parallel board ( scrap ) ,
and flip one side after crosscutting ,
if it is square , it will close exactly ,
if not , you will have a ’ v ’ on one side or the other .

adjust accordingly .

I agree with patron, better method than what I suggested.

Thanks guys. That is exactly what happens with the squared board. I will go try to figure out how to adjust it. Anyone have any hands-on experience with this in a Porter Cable?

there has to be some adjusment somewhere there ,
i don’t know that tool ,
but they all have it ,
i did work with a hitachi ,
that had that problem ,
and it was the fence that could be adjusted ,
i had never seen that before ,
but and allen wrench and a little tweeking , and good to go .

Thanks Patron. It turned out to be the fence on here too. It is bolted on and apparently got bumped.

Make sure that fence is good and tight! That must have been one serious bump. On my PC compound miter saw, there is an adjusting screw under the locking knob that has an eccentric on it. You loosen the nut and turn the screw to get it into square. I had just mitered a set of oak boards to make a window frame style picture frame, and the alignment was terrible.
