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
    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

  • 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 4.5 out of 5 by 59.
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 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.

Rated 1 out of 5 by from Don't buy this saw I am a home owner and have owned several Stihl's in the past and wanted another professional saw. I purchased this saw expecting high quality and have been completely disappointed in the performance of this "professional" saw. If you set the saw down for more than 5 seconds and go to pick it up it does every single time. Have to pull it over 3 times every time it does in order to get it to restart. I have had the saw in the shop 4 times for the same issue and all I am told is that is nothing they can do. Finally did a rebuild on the carb and there was little improvement and now as soon as the saw warms up it is right back to the same issues. If you are moving around with the saw at all or picking the saw back up dies every time. Not only am I disappointed in the saw but in the level of service I have gotten when purchasing a pro-grade saw. I certainly would not want to be a professional having to rely on this piece of equipment.

Rated 1 out of 5 by from Over rated If your a professional using this saw then you will soon find that it has issues running. When your in the middle of a crucial cut and you need the power and quickness to get through your cut you will soon be let down. It will start choking out and cutting out. When you move from one location to the next it will die continuously and then have issues restarting. Yes you can reset this saw and it will run excellent and be the greatest saw ever, at least for the next 5 minutes of cutting then back to running like crud.

Rated 5 out of 5 by from Perfect arborist saw. This saw is my favorite saw , its perfect . I used this one time when blocking down a humongous silver maple tree. And it cut though like butter. For me its an all around perfect saw for the arborist. And for the ground guys too.

Rated 5 out of 5 by from The Animal There is a reason it's nickname is the animal. This saw will not disappoint. I own my own contracting business and we take down a lot of trees. When you get to the big stuff you reach for the animal. Enough said!!!

Rated 5 out of 5 by from Love this saw Easy to start thanks to the M-Tronic management , even in cold weather. I admit I had reservations about changing from a classic adjustable card. But I can't say enough good things about the time it has saved. Great power to weight, it is now my go to saw for intermediate to large jobs.
