MS 271 FARM BOSS®
Powerful, fuel-efficient chainsaw with reduced-emission engine technology that’s built tough for felling, firewood cutting, and storm cleanup tasks.
The MS 271 FARM BOSS® replaces the mighty MS 270 with a saw that’s loaded with features and technology. It starts with a highly efficient engine that delivers 20% longer run times between refuelings – while cutting exhaust emissions in half compared to the MS 270. There’s also a pre-separation air filtration system that’s so effective, your air filter can last up to five times longer (now that’s high performance). All engineered into one compact, ergonomic design.

Important Information
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.
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.
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.

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. -
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. -
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.
