The MS 391 features \u003cstrong\u003eSTIHL®\u003c\/strong\u003e engine technology that adds fuel efficiency while reducing exhaust emissions, as compared to other chainsaw 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, \u003cstrong\u003eFARM BOSS®\u003c\/strong\u003e, 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\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntelliCarb™\u003c\/strong\u003e Compensating Carburetor - The \u003cstrong\u003eIntelliCarb™\u003c\/strong\u003e 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. \u003cstrong\u003eIntelliCarb™\u003c\/strong\u003e 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 \u003cstrong\u003eIntelliCarb™\u003c\/strong\u003e 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\/li\u003e\n\u003cli\u003eBumper Spikes - These spikes prevent pull-in and provide better control, making cutting easier.\u003c\/li\u003e\n\u003cli\u003eToolless Fuel and Oil Caps with Retainers - Simply lift the lever and twist the caps to remove or tighten. There’s no need to use a tool to tighten or loosen.\u003c\/li\u003e\n\u003cli\u003ePre-Separation Air Filtration System - This 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. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.\u003c\/li\u003e\n\u003cli\u003eSide-Access Chain Tensioner - 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.\u003c\/li\u003e\n\u003cli\u003eAnti-Vibration System - \u003cstrong\u003eSTIHL®\u003c\/strong\u003e has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The \u003cstrong\u003eSTIHL®\u003c\/strong\u003e anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaster Control Lever™\u003c\/strong\u003e - The \u003cstrong\u003eMaster Control Lever™\u003c\/strong\u003e is an easy to use single lever, operating the choke, starting throttle lock, and on-off switch. The operator must pull the throttle trigger before moving the \u003cstrong\u003eMaster Control Lever™\u003c\/strong\u003e to the choke position.\u003c\/li\u003e\n\u003cli\u003eThrottle Trigger Lockout - This safety feature must be depressed before the trigger can be activated.\u003c\/li\u003e\n\u003cli\u003eHigh-Tech Polymer Housings - Housings are lightweight, withstand greater impact, and are corrosion-resistant.\u003c\/li\u003e\n\u003cli\u003eReduced-Emission Engine Technology—Caring for Nature - The \u003cstrong\u003eSTIHL®\u003c\/strong\u003e Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. \u003cstrong\u003eSTIHL®\u003c\/strong\u003e Inc. defines “low exhaust emissions” as being cleaner than EPA and\/or CARB exhaust emission standards.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecification:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Source:\u003c\/strong\u003e Gas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePowerhead Weight:\u003c\/strong\u003e 13.67 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGuide Bar Length (Recommended):\u003c\/strong\u003e 20 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOILOMATIC® Chain:\u003c\/strong\u003e 3\/8\" RS3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChain Oil Capacity:\u003c\/strong\u003e 11.8 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Power:\u003c\/strong\u003e 4.4 bhp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Capacity:\u003c\/strong\u003e 20.3 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplacement:\u003c\/strong\u003e 64.1 cc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended Use:\u003c\/strong\u003e Farm\/Ranch\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STIHL (MID ATLANTIC)","offers":[{"title":"Default Title","offer_id":54127992897835,"sku":"1140 200 0757","price":869.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0924\/6962\/5131\/files\/e26c378c-947c-4e15-98ca-987a3cd9381c.jpg?v=1783542737","url":"https:\/\/www.arbortechsupply.com\/products\/stihl%c2%ae-ms-391-25-w-filing-kit","provider":"Arbor Tech Supply LLC","version":"1.0","type":"link"}
