Probably a long out of date question but my suggestion is to purchase a link style belt to replace the old hard drive belt that comes with the saw. It'll deliver more power to the blade, run quieter and work better. I also recommend replacing the drive pulleys while you're at it. Get a couple of balance ones.
You can get a link belt at Rockler or other woodworking outlets.
