Description:

The STIHL® MS 391 features STIHL® engine technology that adds fuel efficiency while reducing emissions as compared to other models. Though equal in weight, the MS 391 is more powerful than the MS 311. Add to that an optimal power-to-weight ratio and you have a chainsaw that is cut out for the big jobs in field, FARM BOSS® and ranch. Felling trees, cutting firewood and clean up after the storm just got a whole lot easier with the rugged MS 391. Comes standard with 10 tooth bar nose sprocket.

Features:

• The 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.
• The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.
• The STIHL® anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
• The IntelliCarb™ compensating carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine's correct RPM.
• IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel.
• The air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow.
