Keep your chain sharp and clean the bar grooves and inside the face plate. Make sure oil is getting to the bar! I wouldn't go any bigger than a 18" bar with a 250/251 which I believe is the maximum length you can put on it. I wouldn't bury the the blade as it will likely stall. It can cut wood bigger than the bar length but that saw doesn't have an adjustable oiler. So if you are going to be making lots of cuts, one after another especially you will overheat the bar. A MS 290/291 is a good step up with an adjustable oiler that will pull a 20" bar. Good luck and be safe!
