    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.

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…

Rated 5 out of 5 by from No vibration, cuts like a hot knife through butter. I have been cutting wood since the mid 70 s. I still have and use my first D 15. I believe it was built to last forever and so far it is proving me right! I just bought a Farm Boss for some heavy cutting on the farm. (Storm Damage) Made a tough job a peace of cake. Thank You Stihl.

Rated 1 out of 5 by from EXTREMELY DISAPPOINTED!! I can't express enough my complete disappointment and lack of satisfaction with the Stihl Farm Boss chain saw I recently purchased...:( I was in the market for a new saw and had every intention of going to one of the big box hardware stores and buying something there. However, a couple of my buddies talked me into going to Ace Hardware and speaking with the Stihl representative...as they claimed the Stihl was a far superior product. I did speak to the local Stihl rep...and purchased a Farm Boss saw and a new Stihl weed eater.I took the saw back to my farm, put in the correct gas mix and bar oil...and proceeded to limb trees for about an hour...when the saw began to lose power...and died. I attempted to restart the saw for several minutes to no avail. I was a little annoyed that it had already failed so soon after my purchase...but, things happen, I thought. I returned the saw to the dealer where I purchased it in Greensboro, NC...and was told that some sort of failure in the motor occurred...and they would call Stihl to ask how to proceed. That was 3 weeks ago! I have still not received a call from the dealer...no replacement saw has been offered...nothing...:/ For all the hype and touting...and extra expense...this entire experience has left me with a very bad opinion of Stihl and their customer support and satisfaction concerns...:/
