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\u003cdiv class=\"highlights\"\u003e\n\u003ch2\u003eHighlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePowerful all-purpose gas chainsaw for firewood and timber construction\u003c\/li\u003e\n\u003cli\u003ePractical decompression valve for efficient starting\u003c\/li\u003e\n\u003cli\u003eFor work in agriculture, construction, and horticulture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"spec-table-wrap\"\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable class=\"spec-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eDisplacement\u003c\/th\u003e\n\u003ctd\u003e3.9 in³\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e4.4 BHP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDevice weight without refuelling\u003c\/th\u003e\n\u003ctd\u003e13.8 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSystem weight without refuelling\u003c\/th\u003e\n\u003ctd\u003e16.7 \/ 17.0 \/ 18.5 \/ 16.2 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower-to-weight ratio\u003c\/th\u003e\n\u003ctd\u003e3.1 lb\/hp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBar length\u003c\/th\u003e\n\u003ctd\u003e18 \/ 20 \/ 25 \/ 16 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGroove width\u003c\/th\u003e\n\u003ctd\u003e50 \/ 63 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSaw chain pitch\u003c\/th\u003e\n\u003ctd\u003e3\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDevice length with bumper spike\u003c\/th\u003e\n\u003ctd\u003e18 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVibration level left\u003c\/th\u003e\n\u003ctd\u003e13.1 ft\/s²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVibration level right\u003c\/th\u003e\n\u003ctd\u003e13.1 ft\/s²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\u003cdiv class=\"features-block\"\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cdiv class=\"feature-item\"\u003e\n\u003ch3\u003eAnti-Vibration System\u003c\/h3\u003e\n\u003cp\u003eSTIHL 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\u003cdiv class=\"feature-item\"\u003e\n\u003ch3\u003eMaster Control Lever™\u003c\/h3\u003e\n\u003cp\u003eThe Master Control Lever™ is an easy to use single lever, operating the choke, starting throttle lock, and on-off switch.
