Chainsaw selection. Try to match the abilities of the user and capabilities of the saw to the job task. Pros will use pro tools, which tend to have more horsepower and more weight. They are experienced to handle it. In the case of chainsaw operation, a lighter saw is easier to control for the occasional user. Bigger is not better, (Please all experienced operators may dispute this but they have one thing beginners do not respect and experience of the tools) There are two types of fuel for your chain saw each has advantages and disadvantages both have the same maintenance of the chain and bar. Electric chainsaws can be bought cheap No gas engine repairs and power on demand. My recommendation is 3hp plus 14 to 16” bar. Besides being restrictive due to a power cord they also tend to cut slower. But they are lighter and easier to handle. No fussing with gas oil mixtures either. No need for ear protection and no sucking in gas fumes. I use one and cut up about 4 cords a year from gathered up logs. It last about 4 years and I work it Gas saws requires gas engine maintenance, Proper mixing of gas and oil, and proper storage. Even the cheap ones cut faster than the electric ones. They allow one to cut where it is not practical to find an electrical outlet. Ear shattering noise, noxious fumes, but can’t be beat in remote locations or heavier duty work felling decent size trees. Word on safety: Temporary hearing loss is not a bad thing, when your spouse is giving it to you, all other times wear protection. Nothing ruins a quiet Saturday than a trip to the emergency room to get your eye flushed out and lucky that’s all it takes. Wear eye protection at all times Good leatherwork gloves could save a nasty injury. Flip-flops are not standard foot protection especially if you use your toes to count with. IF you don’t have steel toe work boots, one dropped log on your toes and you will wish you had steel toes. I know pros that even wear leather chaps but Khakis and shorts are not the way to go. I am not saying you have to dress like Robo Cop, but think of what you are doing . jumping around, over reaching or tripping with chainsaws is very dangerous. Keep the work area clean to avoid tripping. If not comfortable falling a tree seek help also plan a clear escape path should things go wrong. The last thing to do is worry about the saw. Just get the hell out of there as fast as you can.
