I just bought a new Stihl TS400 saw. Is there any reason why you would not want to hook up a hose for water supply to the saw when you are cutting concrete blocks and caps for retaining walls? From what I understand - it keeps the cancerous dust clouds down, and makes the blade last longer, right? I know I may not always have access to a water supply but while I do I should use it right (for concrete anyway)? Is there anything else to know about this saw? It seems to be really nice. I use Stihl products exclusively and am very satisfied with all the other stuff I have so that is why I got the saw. There stuff seems to be bullet proof. Except for the weed eater that got ran over by the bobcat!
