You bought one from Home Depot and had a problem which they would not take care of. Then you buy another one from Home Depot and have another problem. Did you learn anything yet? Stop by a local dealer who sells chain saws. If you do have a problem, I'll bet they will take care of it and probably at no cost to you. They will keep their customers happy or loose buisness. Many of Home Depot and Lowes items are not the same ones that you buy from a dealer. They get a cheaper wholesale cost because the manufacturer will build it with much cheaper parts. Don't know why many people haven't learned this yet. You get what you pay for!!
