Removing Arbor Screw on Circular Saw

[patlaw]

The screw in the arbor holding the blade of my new Porter Cable 6-1/2" battery circular saw is so tight that I cannot loosen it. Sure, I can force it, but if I strip the Allen head or break the screw, it's my problem. Should I take it back to Lowe's and let them try? The screw is a reverse thread, isn't it?

It shouldn't be a reverse thread; else the blade would fly off!

 

[Mike Camp]

Is it a right or left blade saw?

 

[patlaw]

Right. It's a Porter Cable PC18CSL. My wife is going to take it by the service center on Capital Boulevard to let them break it.

My PC circ saw is not reverse thread. I think you see that mostly with miter saws.

I'll know for sure in a little while when my wife gets back home with it. The guys at the service center sort of laughed when she said I couldn't get the bolt loose. The counter guy was unable to get it loose, and one of the guys from the back had to come out and do it. It took a lot of work for them to loosen it.

That's a strange occurrence imo. With the spindle lock button and allen wrench there should have been plenty of applied torque to loosen that bolt. No way that it should have been that tight right out of the box when turning counterclockwise.
