  • STIHL Easy2Start™ (E)
    The STIHL Easy2Start™ system makes starting STIHL outdoor power tools almost effortless, eliminating the need for a strong pull of the starting cord. This advanced starting system is designed to make starting STIHL products easier. The specific system may vary by model, but in each case, a quick pull overcomes the engine’s compression to minimize the strength and effort required to start. Available on selected products.
  • Quick Chain Adjuster (QCA) (B)
    The Quick Chain Adjuster (QCA) (B) allows the user to adjust the tension of the chain without the use of tools. This allows for easy chain adjustment.

Rated 5 out of 5 by from Reliable I have been using this saw for 2 years now and is the best one I have ever owned. Always starts (easy) and doesn't weigh you down using all day. My saw went under water in a flood for 3 days, I dried it out and and cleaned it up, started right away and runs like new.

Rated 5 out of 5 by from This is an excellent saw! I am very impressed with this chainsaw! I am a new home owner, and I just purchased a large load of logs to cut up for firewood (to heat my home). I had been feeling intimidated by how much cutting I had to do. The first day I used my new MS 251 C-BE, I no longer felt at all overwhelmed by my huge pile of oak logs. The saw starts so easily, cuts so quickly, and uses so little fuel that my large job now seems like a walk in the park! I also really appreciate how light and comfortable the saw is to use, and how easy it is to adjust. I had heard many good things about Stihl chainsaws, so I had very high expectations. This saw has exceeded even my high expectations, and I am very, VERY pleased!

Rated 1 out of 5 by from Won't start after 1 use! Have many Stihl prod's. Purchased a 251ce chain saw. Bought the motomix fuel. Used it 2 weeks after purchase to cut a downed ash about 12 feet long. Started right up, worked like a champ. Didn't finish job, attempted to start 4 weeks later. No go. Took to dealer, couldn't be started, left at shop. Hoping I don't receive a large repair bill or it's going in trash.

Rated 5 out of 5 by from Great purchase This saw is the easiest to start out of any saw I've ever operated. It's almost eerie how easily it starts. Cut through chunks of a 65' tall maple like it was butter.

Rated 5 out of 5 by from Best chainsaw that I've ever owned. This truly is a great chainsaw. It is extremely easy to start and to adjust chain tension. It has plenty of power for any homeowner task. This is about the sixth chainsaw that I've owned, but my first Stihl. If I ever need another one, it will definitely be a Stihl.
