I tried Google but as far as i went, no luck. My dad needs it for his saw i guess. Any help is appreciated! Thanks!

I realize this is kind of broad, but if you could even explain just one of these it would be helpful. The internet hasn’t proven successful with my searches to these questions. : o (
Thanks for all of your helpful answers!!!

how do i oil a 10 in. cummins miter saw? asap plz

I plan on installing crown molding all throughout my house and I want to use my DeWalt 10" Single Bevel Miter saw to make the cuts. It came with a 40 teeth blade. Is that enough teeth to give a sufficiently smooth finish?
