A high-performance, fuel-efficient chainsaw. Great for felling, firewood cutting and storm cleanup.
Another high-tech STIHL chainsaw, the MS 291 is built around one of our new fuel-saving engines with longer run times and lower emissions. And with an advanced pre-separation air filtration system, your air filter can last up to five times longer. Another great feature is an advanced anti-vibration system to reduce user fatigue. STIHL engineering is to thank for this high-powered, high-tech, low-maintenance chainsaw. It is truly a force to be reckoned with.

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
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…

Common Features for Chainsaws
View the features common to many STIHL chainsaws.
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.
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.
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.
You Will Also Need
Don’t let friction cut down your chainsaw’s performance. STIHL bar and chain oil is specially formulated to adhere to your chainsaw’s bar and chain, providing optimal lubrication. Special oils help prevent sap and pitch from clinging, prolonging cutting performance and the lifespan of your chain parts. Ideal for use in moderate temperatures, STIHL bar and chain oil provides quality protection for your chainsaw – bar none.
No matter how you slice it (or trim it or shred it), there’s no better protection for your high performance 2-stroke engine than STIHL HP Ultra. This 2-cycle engine oil has outstanding engine cleaning characteristics, plus “ultra” lubricating qualities that are superior to other 2-cycle engine oils. This fully synthetic oil is also highly biodegradable, degrading by 80% in 21 days. We’re so confident this oil will protect your engine, we’ll double your STIHL limited warranty* when you use it. It’s that good.
*Double your warranty when you include STIHL HP Ultra Oil (six 2.6-oz. bottles) or STIHL MotoMix® premixed fuel (six 32-oz. cans or a 1-gal. container) with your STIHL product purchase. Double limited warranty protection applies to STIHL gasoline-powered products purchased and registered for personal non-income producing, family and household purposes only. Other restrictions apply. See dealer for details.

No-Spill® fuel containers advance convenience and quality in gasoline-can design by reducing emissions of hydrocarbons from evaporation, permeation and spillage. This helps protect the environment as well as saves you on fuel costs due to waste. Each container is molded from fluorinated, high molecular weight material for low permeation. The thumb-button flow control allows filling even smaller-sized tanks reducing the risk of spilling and is designed to stop the flow automatically when the tank becomes full to prevent overflowing. Built on a wide and stable base for less likelihood of upsets and equipped with child-resistant closures, all No-Spill® containers comply with both EPA and CARB requirements. With 1¼-gallon, 2 ½-gallon and 5-gallon sizes available, you’re sure to find one that fits your needs.
For Your Safety
The woods can hold many dangers. Stay one step ahead with the Forestry Helmet System from STIHL. The protection starts with a hard shell of ABS thermoplastic. It gets even better with a six-point, ratchet-style suspension system that absorbs shock and keeps the helmet stable while you work.
The system also features a Cool Guard sweatband to keep perspiration out of your eyes, as well as a built-in rain gutter to direct rain away from your face during inclement weather. Adjustable hearing protectors comfortably reduce noise while an epoxy-coated steel full-face screen helps protect from flying debris.
Hard hat meets ANSI Z89.1-2003 Type 1 Class G. Hearing protectors meet ANSI S3.19-1974 and have a Noise Reduction Rating (NRR) of 24 dB(A).
Reduce the vibration from handheld machines with anti-vibration gloves from STIHL. The palms and fingers are specially designed to absorb vibration energy, helping you stay steady throughout your workday.

Wearing protective apparel on the jobsite is critical – especially when cutting near active roadways. The Performance Hi-Vis Apron Chaps feature Hi-Visibility Nylon Fabric that is visible by motorists traveling up to 50 mph. This meets the Class E reflective requirements and earns a Class 3 reflective rating when worn with the Class 2 reflective vest. The chaps also feature reflective tapes made from Reflexite Brilliance Series GP-340. And when it comes to cutting protection, these chaps include six layers of Avertic™ Pro by Engtex® cut retardant material, designed to reduce the risk or severity of injury in the event of contact with the rotating saw chain on a gasoline-powered chainsaw.
Available style: Reflective Tapes - Reflexite Brilliance Series GP-340
