Rated 4 out of 5 by Great mid-size saw Over all this saw has worked amazing. After about 30 starts the pull cord broke, but it was a quick easy fix with some 550 cord. April 22, 2016

Rated 1 out of 5 by This product is garbage The chainsaw has not worked right ever since I bought it. I can't even get it to start and it has leaked oil and fuel since the first day. It is a horrible product and I will never buy another Stihl product again. April 14, 2016

Rated 5 out of 5 by This product takes care of all my needs. This product is great for me. I use it as needed around the farm and strongly recommend it to others. It is sturdy and holds up to every job I use it for, thanks STIHL. March 31, 2016
Rated 2 out of 5 by Not what I expected Starts quick and runs all the time. I wish it cut like I expected. I've had issues with the chain oil. I get smoke when I cut so i know the oil system has an issue. Love my blower but wish I had picked a different saw - or I wish I had a version of my saw that works perfect. Bummed :-( March 23, 2016
Rated 5 out of 5 by Nimble but powerful for the woodcutter I got this for a christmas present last year as we were going to a fireplace insert to save on home heating energy bills. I used this saw all summer, fall and winter and it has been excellent. Its light and nimble but has plenty of power and starts up like a dream. I also have a 362cm for large stuff and it is also an excellent saw but I find myself using this woodboss much more often. I highly recommend it. I would say I actively cut firewood every other weekend. March 11, 2016
Rated 5 out of 5 by Perfect Homeowner Saw This is the first new saw I have purchased and have always had hand me downs. Saw has plenty of power and is balanced enough for bucking or limbing. From day one I used the RS .325 .63 Yellow chain and the saw now cuts like a Stihl branded saw. Wear your chaps and wear your gloves and helmet and respect your saw, This isn't a weed eater your playing with. 1# key to safety is to not put your legs, feet or head in the follow through path or kick back path of the saw. Seems like common sense but you know the saying. When you walk with the saw, use the brake, that's what its there for. Tripping with a running saw is easy to do and will make you have a bad day.The green chain takes 2-3 times longer for the same cut as the yellow RS chain. The Stihl 2 in 1 file is a must when running Chisel chain. As soon as the saw stops throwing chips and is making saw dust then you need to touch up the teeth with the file. Use the green chain for cutting up that dirty dead wood trees that is full of ant holes. You would be surprised how much dirt ants bring into a tree. I'm not a big fan of the single bar nut but it does make it easier to get the side case off and clean up the saw. There is a metal collar that the nut cranks down on so its not just cranking down on plastic. The chain will slack when its hot so don't immediately rush to tighten it. I highly recommend the Oregon 100961X Power Mate Sprocket System over the paddle wheel design. The chain seems to pull better through wood and less wear and tear on the saw. I use the .325 7 tooth sprocket. Not sure why Stihl doesn't make a rim sprocket for this size saw. Cold starts are easy, 1 or 2 pulls until the saw burps then move the choke up one click and it starts every time. Warm starts it will normally start with the choke on run with 1 or 2 pulls. I only run the Moto Mix in my Stihl blowers so I normally have a gallon on hand for the saw. You can run premix but make sure it is ethanol free gas. There is a lot of plastic on the saw so only time will tell if it holds up. There is a trade off of weight vs. durability. Over all I'm pretty happy with the saw. March 1, 2016
