Description:

The MS 261 chainsaw delivers low exhaust emissions, high fuel efficiency, and, of course, professional-grade performance. Its redesigned cylinder and ergonomic housing deliver a great power-to-weight ratio, weighing just 10.8 lbs. Designed for large volume cutting, the MS 261 also features the STIHL® anti-vibration system for enhanced comfort. Other convenience features include a pre-separation air filtration system and a redesigned spiked bumper. Add the MS 261 to your jobsite today.

Features:

• Ematic™ Lubrication System – The Ematic™ guide bar, when used with STIHL OILOMATIC® 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 by up to 50%.
• STIHL ElastoStart™ – The ElastoStart™ starter handle is an exclusive feature of STIHL®. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The ElastoStart™ starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces that occur at the grip after the first compression stroke are smoothed out.
• IntelliCarb™ 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. This is in contrast to typical carburetors that utilize air from the “dirty” side of the air box.
• STIHL Quickstop® – STIHL® chainsaws are equipped with a chain-stopping system designed to reduce the risk of injury in certain kickback situations. It is called a STIHL Quickstop® chain brake. The Quickstop® 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 Quickstop® chain brake can be activated by inertia, stopping the chain within fractions of a second.
• Bumper Spikes – These spikes prevent pull-in and provide better control, making cutting easier.
• Adjustable Automatic Oiler – The Adjustable Automatic Oiler allows the user to adjust the lubricant flow for the guide bar and saw chain based on different bar lengths and cutting conditions.
• Decompression Valve – The decompression valve, also referred to as a “deco” or “deco valve,” vents compression in the cylinder for easier starting. It 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.
• Pre-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 heavier dirt particles before being routed to the air filter. This means less dirt reaches the filter, resulting in reduced maintenance.
• Side-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 compared to the typical location of the guide bar adjustment screw.
• Master Control Lever™ – The Master Control Lever™ is an easy-to-use single lever that operates the choke, starting throttle lock, and on-off switch. The operator must pull the throttle trigger before moving the Master Control Lever™ to the choke position.
• Anti-Vibration System – STIHL® has developed a system for minimizing vibration levels in handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
• Toolless Fuel and Oil Caps with Retainers – Simply lift the lever and twist the caps to remove or tighten—no tools needed.
• Throttle Trigger Lock – See it in action!
