Topic tags/keywords: pcb270ts table saw fence

I have had the Porter Cable Stationary saw PCB270TS for about three years now. It has been a great saw, but sometime in the past year the locking mechanism sticks. So when I need to adjust the fence, I lift the fence lever but it does not unlock (I have to reach under the fence and manually flip the loving lever. If I remove the fence and perform the lock/unlock it moves freely and appears to work fine. Anyone else experience this issue? Do I need to lubricate, disassemble the mechanism or something like that. Or is there some other fence I need to purchase?

Any thoughts appreciated!

It sounds like something is either broken or binding up when the fence is on the table. I would first try cleaning everything and lubricating the larger parts, table and rails with paste wax, and the smaller workings of the lock with dry lube. I wouldn’t go disassembling too much until I knew that cleaning/lubrication did not help. I have a Bosch 4100 and it’s a night and day difference between when it needs to be waxed,and after its been waxed. Good luck.

Mine does the same thing especially in cold weather. There is a little spring that is designed to pop the fence lose when you raise the handle. Try rinsing it with carb cleaner and dry lube it.
