{"product_id":"stihl®-ms-661-magnum®-chainsaw","title":"STIHL® MS 661 MAGNUM® Chainsaw","description":"\u003ch1\u003eDescription:\u003c\/h1\u003e\u003cp\u003eThe \u003cstrong\u003eMS 661 MAGNUM®\u003c\/strong\u003e professional chainsaw delivers the reliable power and rugged dependability you need for felling, de-limbing, and bucking large diameter trees. This chainsaw features a simple, proven, and non-electronic design. A fuel-efficient engine and low-maintenance air filtration system help keep operating costs low, while the \u003cstrong\u003eSTIHL\u003c\/strong\u003e anti-vibration management system reduces fatigue and improves handling when compared to the previous model, even when using long guide bars. The \u003cstrong\u003eMS 661 MAGNUM®\u003c\/strong\u003e chainsaw is the perfect partner for forestry, municipal, and tree service professionals.\u003c\/p\u003e\u003ch2\u003eFeatures:\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmatic™\u003c\/strong\u003e Lubrication System - The \u003cstrong\u003eEmatic™\u003c\/strong\u003e guide bar, when used with \u003cstrong\u003eSTIHL® OILOMATIC®\u003c\/strong\u003e saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSTIHL® ElastoStart™\u003c\/strong\u003e - The \u003cstrong\u003eElastoStart™\u003c\/strong\u003e starter handle is an exclusive feature of \u003cstrong\u003eSTIHL®\u003c\/strong\u003e. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The \u003cstrong\u003eElastoStart™\u003c\/strong\u003e starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces which occur at the grip after the first compression stroke are smoothed out.\u003c\/li\u003e\n\u003cli\u003eHD2 Air Filter - The HD2 air filter on this unit is washable, providing extremely long filter life and lowering maintenance costs. The large surface area allows for longer run times between cleanings and high performance even while operating in dusty and dry conditions. Overall, the HD2 air filter provides better protection of the engine compared to standard air filters.\u003c\/li\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\u003e\n\u003cstrong\u003eSTIHL® Quickstop®\u003c\/strong\u003e - \u003cstrong\u003eSTIHL®\u003c\/strong\u003e chainsaws are equipped with a chain stopping system designed to reduce the risk of injury in certain kickback situations. It is called a \u003cstrong\u003eSTIHL® Quickstop®\u003c\/strong\u003e chain brake. The \u003cstrong\u003eSTIHL® Quickstop®\u003c\/strong\u003e chain brake is designed to stop the rotation of the chain if activated by the operator’s hand or by inertia if the saw kicks back with sufficient force. In some working positions, the \u003cstrong\u003eSTIHL® Quickstop®\u003c\/strong\u003e chain brake can be activated by inertia, stopping the chain within fractions of a second.\u003c\/li\u003e\n\u003cli\u003eBumper Spikes - These spikes prevent pull-in and provide better control, making cutting easier.\u003c\/li\u003e\n\u003cli\u003eLightweight Sprocket Cover with Captive Bar Nuts - The sprocket cover is lightweight and the captive bar nuts are held securely in place for efficient saw chain maintenance.\u003c\/li\u003e\n\u003cli\u003eAdjustable Automatic Oiler - The Adjustable Automatic Oiler allows the user to adjust the lubricant of the guide bar and saw chain for different bar lengths and cutting conditions.\u003c\/li\u003e\n\u003cli\u003eDecompression Valve - The decompression valve, also referred to as 'deco' or 'deco valve', vents compression in the cylinder for easier starting. The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope. It is opened manually and closes automatically as soon as the engine fires.\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\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\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\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\u003eThrottle Trigger Lockout - This safety feature must be depressed before the trigger can be activated.\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\u003eSpecifications\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 16.5 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGuide Bar Length (Recommended):\u003c\/strong\u003e 25 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 13.5 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Power:\u003c\/strong\u003e 7.2 bhp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Capacity:\u003c\/strong\u003e 28.7 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplacement:\u003c\/strong\u003e 91.1 cc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended Use:\u003c\/strong\u003e Professional\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Stihl","offers":[{"title":"Default Title","offer_id":44803698393190,"sku":"MS661","price":1859.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/3570\/1862\/files\/df8247a3-8d18-45bc-8773-363882b323a4.jpg?v=1771374308","url":"https:\/\/apopkamower.com\/products\/stihl%c2%ae-ms-661-magnum%c2%ae-chainsaw","provider":"Apopka Mower and Equipment Repair","version":"1.0","type":"link"}
