Features

Bumper Spikes
Toolless Fuel and Oil Caps with Retainers
Pre-Separation Air Filtration System
Side-Access Chain Tensioner

Another high-tech STIHL chainsaw, the MS 291 is built around a fuel-saving engine with long run times and low exhaust emissions. The advanced pre-separation air filtration system perceptibly relieves the downstream filter components, increasing the life of your air filter. Another great comfort feature is an anti-vibration system to provide you with a more comfortable working experience. It is truly a force to be reckoned with.

Features
- Bumper Spikes -
  These spikes prevent pull-in and provide better control, making cutting easier.
- 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.
- 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.
- 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.
- Master Control Lever™ -
  The Master Control Lever™ is an easy to use single lever, operating the choke, starting throttle lock, and on-off switch. The operator must pull the throttle trigger before moving the Master Control Lever™ to the choke position.
- Throttle Trigger Lockout -
  This safety feature must be depressed before the trigger can be activated.
- High-Tech Polymer Housings -
  Housings are lightweight, withstand greater impact, and are corrosion-resistant.
- Powerful, Yet Lightweight -
  Built for lightweight durability and packed with features, this powerful chainsaw is ideal for frequent use and tasks around the home.
- Made in America -
  A majority of STIHL products sold in America are made in America of U.S. and global materials.

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.
IMPORTANT SAFETY INFORMATION 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 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.
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.
