I have a husqvarna 445, 18"bar. We had some big chestnut oak trees down. Some are probably 24" thick, so I'm burying the bar to cut them up. I keep getting the chain too hot and then the sharpness goes downhill quick. I've cleaned the oiler stuff, and it will sprits some oil when I run the saw full bore next to something where the oil shows up. I don't see any oil adjustment. Some cuts I've stopped half way through to let it cool down a little. Is there anything else I can do? It seems to use maybe half tank of oil for every full tank of gas. Is this a common problem with any type of saw and I'm just pushing it to it's max? Thanks for any advice.
