This is puzzling. I have a Porter-Cable 325MAG circular saw with low miles on it. Very low miles. I've been crosscutting easy stuff lately, plywood and solid poplar, and it's bogging down to the point of stopping.
I checked the obvious dumb stuff -- the blade is facing the correct direction, and the depth is fine. BTW my boards are well-supported, not sagging, and using an edge guide doesn't help.
I've never had this problem before. Any ideas?
Thanks all.
Best,

Have you checked the lube on it? I picked up a Milwaukee worm drive and the lube was low. I had to take it apart and reverse the bushing to get it to run right.

Dull blade ? Too long of an extension cord, brushes wearing on saw, bad bearings, saw doesn't like you ?
One time I did have an extension cord that a several of the copper strands break off the plug, but would still work, cause the tool to be starved of electricity.

I second the power cord starving electric, and brushes.

If the power cord is okay and other stuff already mentioned ,I would try another blade,a combination blade for the poplar and plywood.Try another tool in the same receptacle,that could also be the problem.Then plug into a receptacle on a different circuit and see if that helps.Vacuum dust from motor too.

LIL Thanks everyone! The user manual says no lubrication is necessary through the life of the saw, so hopefully that's not it. Then again, they don't say how long that life is...
I was using an extension cord. That's so ridiculously simple it almost has to be the reason. I'll try some cuts without it.
Appreciate the suggestions.
Yep! Saw works fine without the extension cord. Thanks everyone!

I would bet most people don't understand the need for larger gauge extension cords and of those that do not many like to spend $40+ for a cord. I only buy 12 or bigger myself. My compressor won't fire up on less than 12 and even then depending on the house wiring it won't fire up

My first thought would be the blade. I have the same issue but I know the blade is dull.
