Stihl MS261 Chainsaw Features

Power-packed, eco-friendly, light and compact, the MS261 is considered one of the most revolutionary professional chain saws manufactured by STIHL.

Designed as a step up from the popular MS260, this upgraded model claims improved features like low fuel consumption, reduced exhaust emissions and great ergonomics.

The early MS261 featured carburetor heating, manual adjustment of bar oil delivery, a master start/stop control and tool free filler caps.

It lacked some of the modern refinements that now feature in the MS261 C-M and MS261 C-M VR. The MS261 has benefited from a technology upgrade in the form of the M-Tronic electronic metering system. A high tech addition that all but eliminates manual carburetor adjustment. Later models also feature heated handles; a valuable improvement for winter work.

Positive comments about the MS261

  • The MS261 is a good choice, light with good power.
  • If I was restricted to just one 50cc saw my Stihl MS261 would be it!

Negative comments about the MS261

  • Early models sometimes suffer an issue with the chain brake. This issue can be a symptom of a worn clutch needle bearing. Be aware of this because unattended that issue can create a more serious, and expensive condition of wear on the end of the crank shaft.
  • Later models can suffer fuelling issues caused by calibration drift in the MTronic electronic fuelling system. The operators manual gives (fairly) clear instructions on how to re-calibrate your saw.
