The MS 391 features STIHL 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, 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\u003c\/div\u003e\n\u003cul class=\"primaryProductFeatures\"\u003e\u003c\/ul\u003e\n\u003cdiv id=\"itemGroup\" class=\"productItemGroup\"\u003e\n\u003ch3 class=\"productItemGroupName\"\u003eKey Features\u003c\/h3\u003e\n\u003cul class=\"itemGroupFeatures\"\u003e\n\u003cli id=\"122539433\" class=\"productFeature\"\u003ePowerful all-purpose gas chainsaw for firewood and timber construction\u003c\/li\u003e\n\u003cli id=\"122539434\" class=\"productFeature\"\u003ePractical decompression valve for efficient starting\u003c\/li\u003e\n\u003cli id=\"122539435\" class=\"productFeature\"\u003eFor work in agriculture, construction, and horticulture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"productItemGroupName\"\u003eFeatures\u003c\/h3\u003e\n\u003cul class=\"itemGroupFeatures\"\u003e\n\u003cli id=\"122539413\" class=\"productFeature\"\u003eIntelliCarb™ Compensating Carburetor - 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. 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\/li\u003e\n\u003cli id=\"122539414\" class=\"productFeature\"\u003eBumper Spikes - These spikes prevent pull-in and provide better control, making cutting easier.\u003c\/li\u003e\n\u003cli id=\"122539415\" class=\"productFeature\"\u003eToolless Fuel and Oil Caps with Retainers - Simply lift the lever and twist the caps to remove or tighten.

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 id=\"122539417\" class=\"productFeature\"\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 id=\"122539418\" class=\"productFeature\"\u003eAnti-Vibration System - STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment.
