Same Issue With Saw
I have the same problems with my saw. The paint melts off on the wood and the miter slits stick. I brought the saw to a DeWALT authorized warranty repair center. They called me about three weeks later to tell me it was ready to be picked up. I asked what was done, I was told a tune up. They did not address the paint issue and said the DeWALT miter gauge worked fine in the slot. I was aware of the sloppy gauge before I bought the saw so later bought an Incra miter gauge that adjusts to the saw. When I adjust the gauge correctly in one spot and slide it, it binds, so it is probably not the sled you made but the slots in the table. I am waiting for DeWALT corporate to get back to me because they don't have any service / tech support you can speak with when you call there.
My experience at the service center was less than I expected. On my first visit to drop it off I was told they were probably going to replace the saw, they would call me later to let me know. Of course I had to call them, when I did they said DeWALT was sending a new table, they would call me when it was done in about a week. I made sure they were going to adjust it after they replaced the top, they said yes. Two weeks later I called to find out what was going on, they said it would be worked on before the end of the week. I got a call to only find out they tuned it up but did nothing to alleviate my problems. They explained several times the miter gauge works fine and asked me what do I want him to do, heat up the table and test it? I do factory authorized service for several brands of office equipment, if I did what they did I would be on the phone getting an earful from corporate.
I understand that it is a jobsite saw and not built to produce fine furniture but the problems you and I are having are jobsite quality issues. I will follow up when I get my answer from DeWALT
