Talk about loaded. The MS 291 C-BEQ has the same high-tech engine and low-maintenance pre-separation air filtration system, and the same advanced anti-vibration system for user comfort as the MS 291. To which we add our easy-to-use toolless Quick Chain Adjuster. The STIHL Easy2Start™ system. And our Quickstop® Plus – an additional chain braking feature – for possibly the easiest starting (and stopping) chainsaw you ever fired up.
