MS 311

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.

STIHL products sold through U.S. STIHL Dealers are for distribution in the United States only.

Reviews

MS 311 is rated 4.6 out of 5 by 184.
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 1 out of 5 by from Product is VERY Over Rated Hard to start from day one, saw doesn't want to run when first cranked unless it runs open throttle for a minute or two. If you idle it down sooner, every time I hit the trigger it bogs out dead. If the engine is cold many time it does not want to idle. Even when the engine is warm it can be difficult to crank. Boggs down on 12' mesquite, saw lacks power badly! No where close to satisfied with the performance or lack thereof, of this saw. I have never been this disappointed in any Stihl saw and I've been running them over 34 years.

Rated 5 out of 5 by from Easy start, powerfull, good controls and easy refill. Great saw. Easy starts (use Stihl fuel), adjustments are straightforward and easy to do in the field. Primary use is cut logs down to size, and resaw. All good.

Rated 5 out of 5 by from Best chainsaw I've ever owned! I've always heard how good the Stihl products are. I own 2 other chain saws but they let me down in one way or another. The MS 311 is an absolute beast.

Rated 5 out of 5 by from MS311 gets the job done The Stihl MS311 chain saw is a real pleasure to use and it has many excellent safety features. I also bought the Stihl safety chaps, and safety helmet with the face shield and hearing protection. All are quality products.

Rated 5 out of 5 by from Not my first saw Have had a Stihl 034 AVQ for over 40 years, like me it's getting old and parts are getting harder to find.. This new saw, MS 311, is wonderful with lots of power, easy starts and great construction..Hope I last long enough to buy another

Rated 5 out of 5 by from Great saw for the price Saw is exactly what I needed to cut all types of firewood. The 24 inch bar was a perfect length even when I was cutting 48 inch diameter madrone. This saw has plenty of power.

Rated 5 out of 5 by from EATS WOOD I bought the MS311 debated between that and the MS291. I went for more power because it was only $30 more, I was concerned about the weight, of the MS311 but it was very easy to handle, did not get tired overtime. The extra weight helps cut through big trees faster, just let the saw do the work. This saw probable cuts a 20 inch diameter tree in 15-20 seconds, UNREAL EATS WOOD.
