MS 261 C-M

MS 261 C-M
The same great MS 261, but with advanced STIHL M-Tronic™ technology for optimized performance in various conditions.

Product Description

The MS 261 C-M has all the same great features as the MS 261 – low exhaust emissions, high fuel efficiency and robust performance – but also features the advanced STIHL M-Tronic™ engine management system. With STIHL M-Tronic™, an onboard microprocessor digitally monitors and automatically compensates for changes in your work conditions including elevation, temperature, fuel quality, varying octane levels and dirty air filters. The end result is maximum performance across a wide range of cutting conditions without making any manual adjustments. The MS 261 C-M also features redesigned cylinders and a slimmer, ergonomic housing for an impressive power-to-weight ratio.

Model Features

  • 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.

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 261 C-M is rated 4.7 out of 5 by 148.
Rated 4 out of 5 by from Nice light saw Bought to cut smaller diameter trees and bust up slash piles. Power is about as expected for a 50cc saw. Have a 90 cc saw for most other work. No problem starting and good acceleration unlike other competitors small computerized saws. Ran about 7 tanks gas thru it so far.

Rated 5 out of 5 by from Lightweight work horse I have a Farm boss MS290 that we have used reliably for years. This saw met our need but as we moved to the mountains and put in a wood burning stove, we needed a new saw that was lighter and with good power, not only for felling but bucking as well. We had a tree service come and take down a damaged 80' maple and I saw that their "go to" saw was the MS261. We purchased one and never looked back. Great saw, highly recommended.

Rated 5 out of 5 by from Simply the Best I have owned many saws over the past 30 years and I was hesitant to try the M-Tronic but boy am I glad I did. This is the easiest starting and smoothest running saw I have ever used. The power is unreal for a saw this light too. It flat out eats and begs for more. I'm very very impressed. My MS460 magnum is for sale because It's not in this saws league as hard as that is to believe.

Rated 5 out of 5 by from Great all around saw! I purchased this saw to use around the house and to put in my RZR for when my wife and I are out riding trails. I have medium sized diameter tree's around my house that needed cut back and this saw did that with ease. We also have a wood burning fire place in our home, so, next fall I will be looking forward to putting this saw to work. Easy starting, doesn't get finicky at elevation. I went with the professional series just because I know that they are built a little stouter and have nicer features to them. If someone is wanting a saw for around the house or something that is easy to carry on a side by side or ATV that is dependable and built well, I highly recommend this saw to you! It's well worth the extra money over the 241!

Rated 5 out of 5 by from New to Chainsaws I bought this chainsaw just before Irma hit. In Inverness Fl at Ace Hardware. Great crew of people there. First chainsaw I've ever purchased. I used it a few times to cut up some large oaks that had fell during the storm. I took it back once because I didn't think the chain was being oiled properly. The folks at ACE took it out back and put it through it's paces and showed me how the oil system worked. I think it was a little clogged but it's been working fine since then. After returning to Key West I've been using it daily to cut up softer wood. For me it starts cold in 1-3 pulls and usually one pull after being warmed up. I'm still getting used to the saw and as I stated it's my first saw. I've used a few others in my life. This one feels great as far as vibration and seems to cut anything I put in front of it. I haven't noticed a need for more power but I'm sure folks that use these on a daily basis might require more? I'm very happy so far with the purchase and would buy another Stihl product.

Rated 5 out of 5 by from Great Tool This is about the lightest chainsaw I have ever operated.Very agile and can cut through an oak tree in no time.Very impressed and the quality is above reproach, STIHL has succeeded with this great tool.

Rated 2 out of 5 by from "Upgrade" downgraded This is my second MS261CM. The first one was stolen and it ran like a scolded dog. This new one with a facelift surges and I'm pretty sure the bar isn't perpendicular to the powerhead. I can also feel exhaust coming out of the head. Needless to say it's going back to the dealer. Not impressed. I wish I had my old saw but unless it's found I'm stuck with this over priced MS271. Wait a couple years for the bugs to be worked out.
