I finally got around to picking up a used stihl 16" chainsaw, I put a new blade on it and started cutting up a 3' pc. of Maple about 14" in diameter (freshly felled green wood). I first cut it into 3-1' sections then turned them on their sides and started to half them for bowls. Cross cutting went fast, but cutting the pieces in half was much more difficult (cut on the bark side, not from the top).I only got two cut before the blade was so dull it would cut anything. I was thinking you cut up a whole tree before you need to change or sharpen a blade. Is it typical to need to sharpen the chainsaw blade that quickly?

Thanks, Dale
