The STIHL MS 261 C-M pairs proven professional performance with STIHL M-Tronic™ engine management technology, giving forestry professionals consistent cutting power without the need for manual carburetor adjustments. M-Tronic™ automatically adapts engine settings as operating conditions change, helping provide easy starts and optimized performance throughout the job.
An impressive power-to-weight ratio keeps the saw lightweight and maneuverable, while redesigned bumper spikes provide added leverage and control when putting that power to work. Built to keep downtime to a minimum, the MS 261 C-M features a long-life air filtration system that extends service intervals, so you can spend more time cutting and less time on maintenance.
The STIHL Ematic™ system directs chain oil where it’s needed to help reduce oil consumption, while STIHL Quickstop® is designed to reduce the risk of injury in certain kickback situations. With intelligent engine management, efficient operation, and professional-grade performance, the MS 261 C-M is a dependable choice for demanding forestry work.
