I decided to redo an old birdhouse that had completely rotted out (Granddad built it from plywood 40 years ago), and needed lumber, as my scrap pile in the workshop in the basement didn't have what I needed, and had been depleted from previous projects. Lumber costs have skyrocketed, so I took apart two destroyed pallets normally used to keep bales of hay off the ground. I'd been cutting the nails with a Sawzall and using a handsaw, and it was taking too long, so I broke out the chainsaw. Got the job done in less time than it took me to remove one board the old way.
My own saw is a 011AV from the mid-1980s, which this saw technically replaced last year. I accidentally chipped the chain when I was first learning to use a saw, and the tension needs adjusting. The guy at the dealership who put the new chain on used too much torque on the bolts, so with the proper wrrench that goes with the saw, I could NOT get the cover off to access the tensioner. So, I've been using the MS170. It isn't as well built but is MUCH easier to drag around. The 011AV weighs about 50% more, as the frame/body is magnesium, not plastic. The MS170 seems to start MUCH easier. The MS170 and 011AV use the same chain, and I think bar also, so they're basically directly related to each other. I think, in the US, the MS170 is the smallest gas saw in the lineup.
As I am getting a Ryobi One+ combo kit here soon; I plan to eventually get the chainsaw also. I know these aren't heavy-duty saws, but probably better for small jobs like this.
