MS 441 C-M MAGNUM®

MS 441 C-M MAGNUM®
Powerful professional chainsaw with STIHL M-Tronic™ engine management system.

Product Description

When most people think of STIHL, they think of a no-holds-barred, bulletproof professional chainsaw like the MS 441 C-M MAGNUM®. And for good reason. No chainsaw is designed like it. And no chainsaw performs like it. At the heart of the MS 441 C-M MAGNUM® engine is the STIHL M-Tronic™ engine management system that intelligently manages the operating performance of the engine. (The brains of the MS 441, if you will.) In the field, the M-Tronic™ automatically and constantly adjusts the fuel-air mixture, maintaining maximum operating efficiency under varying conditions like altitude, outside temperature, a dirty air filter or poor fuel quality. The STIHL M-Tronic™ system compensates for these factors by replacing low and high-speed carburetor adjustment screws (old technology) with electronic monitoring of the engine’s performance and digitally optimizing the fuel/air mixture over the entire RPM range (new technology). This intelligent operating system also provides a simplified warm start procedure, and a decompression valve for easier starts. A highly versatile, state-of-the-industry saw for professional-level jobs, the innovations on the STIHL MS 441 C-M system work hard to make your toughest jobs easier. (Wrap-handle version available in select areas.)

Model Features

  • Reduced-Emission Engine Technology - Caring for Nature

    More information

  • STIHL M-Tronic™ 
    This product features M-Tronic™ (M) - a new generation of Intelligent Engine Management that eliminates the low and high speed carburetor adjustment screws, compensates for dirty air filter and changes in elevation and fuel quality for optimum engine power at all times.

    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 441 C-M MAGNUM® is rated 4.4 out of 5 by 64.
Rated 5 out of 5 by from quality and dealer cut at least 14 cords of fire wood a year, I own a ms 170, 362c-m,441c-m, and a 661c-m, my dealer gets me what I ask for every time, had to try this saw out as soon as I got home with it today, and I have to tell you it runs very close to my 2 yr old 661c-m, my dealer opesalisbury.net is great, you will not regret buying this saw

Rated 4 out of 5 by from This could be a good saw if the problem was fixed. I bought my 441 awhile back. Ran fantastic for the first while then started having starting problems. Felling trees in the deep snow made me put the saw on the shelf cus it didnt like running in the snow. Tried using it during the spring/summer/fall but it would run a bit and quit. Got to the point where it simply would not run for more than 5 minutes. I parked the saw for the last 4 years and today I figured I'll try and get it apart and find what its problem is but reading theses posts, I can see others are having the same problems. This also tells me that Stihl has not fixed the situation and has left owners with a white elephant. So sad good product lines have to be bypassed due to getting stiffed.

Rated 5 out of 5 by from Better late than never . Bought a new 441 about 8 years ago from a stihl dealer. It has a 25" bar and I have never needed anything else. This is a professional saw, it is heavy, it has high compression so it's tougher to start, always starts on 5 pulls or less. Runs strong. I run 100ll avgas exclusively and have never had to do anything other than clean the air filter, replace one bar, and sharpen or replace chains. USE NON ETHANOL GASOLINE and you'll never need another saw. This saw has cut over 100 chords of firewood in 8 years.

Rated 1 out of 5 by from I own lots of stihls , this is horrible Bought mine brand new from the dealer, 441 rcm, full wrap m tronic. 25 inch bar and it dogs like i couldnt believe. The saw quality wAs great, but it literally had no power at all. I re calibrated the computer a few times as the manual said and still had no power. Brought it to 2 diff dealers and they told me it was fine. Finally sold it and bought a used 460, put the same bar and chain on, works great. Moral of the story i should of bought the 460 that was on the shelf while they were still avaiable. Do not buy this saw!!!! I still love stihl and premote their products, just not this one!

Rated 2 out of 5 by from Hard to start This saw works great when you first start. When it dies or you shut it off it will not start when it's hot. You will have to wait a half hour to an hour before it will start. Not a professional saw by eney means! I am looking to get rid of it and get something more reliable. I don't know if I will get another stool or not.

Rated 5 out of 5 by from Super Saw cuts big trees, with ease I have used this saw on all my big trees, I have a 25" bar plenty of power and cuts very fast

Rated 5 out of 5 by from Runs like a Beast I had my 441 special ordered and I couldn't be more satisfied within its performance. With about 3 tanks through it, it runs, idles, starts and cuts as it should. When equipped with a full chisel chain, this runs and cuts like a beast. I'm truly impressed with it's power and 'pull' through the cut. I run the 20" ES and 28" ESLite bar and the saw preforms excellent with both. As this saw completes the break in period, I look forward to its full potential.
