The MS 391 features our newest 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’s cut out for the big jobs in field, farm and ranch. Felling trees, cutting firewood and cleanup after the storm just got a whole lot easier with the rugged MS 391.\u003c\/p\u003e\n\u003ctable

Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cb\u003eAnti-Vibration System\u003c\/b\u003e \u003cbr\u003e STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment.

IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As 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. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cb\u003eSide-Access Chain Tensioner\u003c\/b\u003e \u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- \/TABS --\u003e","brand":"STIHL","offers":[{"title":"16 Inch","offer_id":43684255826169,"sku":"MS391 16","price":829.99,"currency_code":"USD","in_stock":false},{"title":"18 Inch","offer_id":43693005144313,"sku":"MS391 18","price":839.99,"currency_code":"USD","in_stock":false},{"title":"20 Inch","offer_id":43693005177081,"sku":"MS391 20","price":849.99,"currency_code":"USD","in_stock":true},{"title":"25 Inch","offer_id":43693005209849,"sku":"MS391 25","price":859.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0462\/0592\/7591\/files\/MS_391.jpg?v=1773756911","url":"https:\/\/mainstreetmowehype.com\/products\/stihl-ms-391-gas-powered-chainsaw","provider":"Main Street Mower","version":"1.0","type":"link"}
