Air is separated with centrifugal force, removing heavier dirt particles and travelling to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning, maintenance, and replacement. The side-access chain tensioner makes it convenient for to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.


  • Mixed-gas powered (2-Stroke)
  • 13.67 lb powerhead weight
  • 16 inch guide bar length
  • 3/8" RS3 Oilmatic chain


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.
