Pros: Almost as good as the pro models without the pro price.
Cons: None so far
I purchased the Stihl MS310 chain saw when I wore out my Stihl MS290 Farm Boss. I decided to stick with Stihl after hearing reports of starting problems with the Huskys. Another reason that I decided on another Stihl is that local dealer support is real good in my area.
Like my former saw, the MS310 is easy to start. Once the machine is warm, it will always start with just one pull with the throttle in "idle".
I opted for the 16" bar, just like my last saw, even though you can go up to a 20" bar with this model. The balance is good, and the single lever control is easy to find. The chain tension is easy to adjust with the provided tool. The fuel and oil caps are tethered to the saw so that you can't lose them, a nice feature. The automatic chain oiler came from the factory set just right, as did the carburetor. A minor quibble, the handle could be a bit larger, I can just barely get the toe of my boot in to hold the saw for ground starting.
Like all gas driven chain saws it's loud, hearing protection is a must! I also wear steel toed boots, hard hat, eye protection and chain saw chaps when using the saw. Although some people question the wisdom of replacing the green "low kickback" chain with the more aggressive yellow chain, I found some yellow chains on sale and have been using them without any problems. I did not notice any real difference in kickback (then again, I cut so as to avoid kickback in the first place) but only a slight improvement in cutting speed.
Even though the Stihl manual doesn't mention this, avoid using outboard motor two cycle oil for the fuel mix. This is probably how I ruined my other saw. I later found out that outboard motor oil is designed for water cooled boat engines, not air cooled small power tools and the oil breaks down under the heat. Even though it is more expensive, I'm only mixing Sthil branded two cycle oil with mid grade gasoline for my saw. I hope to get at least ten years out of this machine, even felling and bucking 6 cords a year.
