Product Description

"This saw is a dream! So easy to start, light enough not to wear me out, and tough enough to work all day! Chain adjustment is simple and the reduced vibration allows me to cut with a greater amount of comfort and confidence. I wish I had bought a STIHL years ago."

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.

Rated 5 out of 5 by from Strong saw that takes care of business! I bought this saw to cut up a pine tree that fell after Hurricane Irma. Gassed it up, adjusted the chain using the quick adjust tool, and went to work. I absolutely love the Easy start system on this machine! It takes almost no effort to pull start it! Just make sure you use either non ethanol gas or premium with your fuel mixture. I've used it randomly for 2 weeks now and am very happy with my purchase. Looking forward to keeping this saw in use for years to come.

Rated 5 out of 5 by from Excellent chainsaw I have used many different brands and have worked on them as well. The Stihl product is solid. It starts easily, runs great. I would highly recommend this saw (18") for most general care that is needed.

Rated 5 out of 5 by from Perfect trail saw I work with trail crews in the mountains of North Carolina. We use chainsaws constantly for clearing downed trees and removing dangerous trees from trail sites. I've worked with a lot of different saws in the last 8 years or so but for the last 3 years I've been using the 251 CBE exclusively. I got it because it was the best compromise between power and weight since I have to carry the saw up and down mountains for sometimes over 10 miles. A lot of the guys on the crew mocked me a bit at first for getting the easy start model but they don't laugh much any more. This saw has worked perfectly in every season and always starts. I used it yesterday for 10 hours on the trail clearing downed trees left by Irma. By the end of the day I was once again thankful for that easy start along with the fast chain adjustment since I had to change chains twice.I have a feeling that a lot of people who are having problems with this (or any) saw need to pay a bit more attention to basic maintenance. For instance, we only use 93 octane gas with no ethanol. If it's available in your area you should start using it right away. This will solve a lot of basic carburetor problems. Also, learn as much as you can about sharpening your chain and flipping your bar. That'll keep the saw cutting straight with no problems.

Rated 2 out of 5 by from Hard to start Once you get this saw started it works great. Very hard to start, floods easy. If it sits for several days the pull rope will not pull. Acts like cylinder is seized. Keep pulling and bang it around for a while and it will finally pull. Takes 40 or so pulls before it fires.

Rated 5 out of 5 by from A homeowner"s dream chainsaw. This saw is a pleasure to operate and start. If I would let her, my 3 year old grandaughter could start this saw. No tools needed to either tighten the chain or replace it. Perfect saw for the novice, but operates like a pro.

Rated 1 out of 5 by from junk This saw is very hard to start if not sits more than a day between usage. It has less power than my old 023. And has been a big disappointment since I bought it.

Rated 2 out of 5 by from Poor Design, Looks good on paper. Had surgery and decided to get an easy start saw. This is the only thing that has been flawless. Plug that holds handle to frame has come apart 4 times so far. Kill switch replaced twice, now I just choke it to kill it. Bar has finally locked up and stopped working. I maintain it regularly and sharpen all my blades before use and during. Cuts at an angle when pressure applied and won't stay on a straight line due to handle flex.
