Model Features

  • Reduced-Emission Engine Technology - Caring for Nature
    The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.

    More information

  • Pre-Separation Air Filtration System
    This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.

    More information

  • Anti-Vibration System
    STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
  • Decompression Valve
    The decompression valve, also referred to as 'deco' or 'deco valve', vents compression in the cylinder for easier starting. The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope. It is opened manually and closes automatically as soon as the engine fires.
  • Side-Access Chain Tensioner
    The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.
  • Toolless fuel and oil caps with retainers
    Simply lift the lever and twist the caps to remove or tighten. There‘s no need to use a tool to tighten or loosen.

Important Information

WARNING! The occurrence called “kickback” can cause serious or fatal injury. Always read the instruction manual carefully before using your saw. STIHL uses a green and yellow color-coding system to help you select a powerhead, bar and chain combination that complies with the kickback requirements of ANSI Standard B175.1 (gasoline-powered saws) and §30 of UL 1662/ ANSI Standard B175.1 (electric chainsaws). Ask your STIHL dealer about safe operating procedures and the advantages of the STIHL Quickstop® chain brake, STIHL Quickstop® Plus (Q) additional chain braking feature, STIHL reduced kickback bars and STIHL low-kickback saw chains.

STIHL recommends the use of green reduced kickback bars and green low kickback chains on all STIHL chainsaws.

* The actual listed guide bar length can vary from the effective cutting length based on which powerhead it is installed on.

Note: STIHL recommends use of fuel with no more than 10% Ethanol content. Using fuel with greater than 10% Ethanol content may cause damage to your equipment and may void your STIHL warranty. Learn More…

WARNING! Improper use of any power tool may cause serious or fatal injury. Read, understand and follow carefully the operating and safety instructions in your instruction manual before using such products.

Reviews

MS 311 is rated 4.6 out of 5 by 192.
Rated 5 out of 5 by from Excellent Saw I bought this saw after reading many reviews on the internet and talking to alot of different people. It has very good power and cuts better than any saw I have ever owned or used. The large chain makes quick work of larger trees and will even rip cut when necessary to split extremely large pieces in halves or quarters. I highly recommend this saw to anyone who cuts alot of wood.

Rated 5 out of 5 by from This saw is very dependable and is a workhorse. I have purchased two MS-311's by Stihl, and I have nothing but good to say about them. I recommend this product to everyone I associate with. When it comes to chainsaws, Stihl is, by far, the best saw I ever used. The company seems concerned about user safety, and have done good things to reduce kickback.

Rated 5 out of 5 by from Superior Saw - A+ I purchased this saw about a year ago when I bought wooded property. I use the 20" bar for most everything and the 25" for stumps. It eats anything you put in its path! I give it a 99 out of 100 - it's a little hard to start after a month without use. This saw and a 193T saw is all you need!

Rated 5 out of 5 by from Very Strong Engine For a 59cc My wife calls it The Beaver! I have a 25 inch bar on it and it cuts Oak and Locust like it's Butter. Very pleased with the MS311 all the way around!!!

Rated 5 out of 5 by from Great saw! Very dependable and has great power I've had the MS311 for a year now. I love it! This saw always starts when I use it, and it chews up trees quicker than a starving beaver. The power is great. I would definitely buy another one, but as dependable as it is, I won't need one for a long time. I would definitely recommend this saw for anyone who uses this saw for around the house farm.

Rated 5 out of 5 by from Beast!!!! This saw is a beast!!!!! This thing eats logs, with any chain. I have a 18" bar and it goes through a tree without a problem. I've used a green chain and a yellow,doesn't matter it will cut through it.
