Description:

When professionals need to fell large trees, in large quantities, they reach for the saw they know has the power to get the job done —the MS 661 C-M. Featuring an impressive power-to-weight ratio and STIHL M-Tronic™ engine management technology, the MS 661 C-M chainsaw also delivers less vibration and 20% greater fuel efficiency than the previous model. Other features include a long-life filter system using HD-2 filter elements to provide longer run times between maintenance, an ElastoStart™ handle, and a high output adjustable oiler.

Features:

  • STIHL M-Tronic™ - This product features STIHL M-Tronic™ (M) - a new generation of Intelligent Engine Management that eliminates the low and high speed carburetor adjustment screws, compensates for dirty air filter and changes in elevation and fuel quality for optimum engine power at all times.
  • 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 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 which 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 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.
  • 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 STIHL 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 STIHL Quickstop® chain brake can be activated by inertia, stopping the chain within fractions of a second.
  • HD2 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.
  • 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 of the guide bar and saw chain for different bar lengths and cutting conditions.
  • Decompression 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.
  • Lightweight 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.
  • 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 as opposed to the typical location of the guide bar adjustment screw.
  • Master Control Lever™ - The Master Control Lever™ 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 Master Control Lever™ to the choke position.
  • Anti-Vibration System - STIHL® has developed a system for minimizing the vibration levels of 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. There’s no need to use a tool to tighten or loosen.
  • Throttle Trigger Lockout - This safety feature must be depressed before the trigger can be activated.
  • Reduced-Emission Engine Technology—Caring for Nature - STIHL Inc.® “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc.® defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.

Soft & fluffy. Stuffy arm rest.
Color: Purple, Color: Purple
Soft and fluffy & my fav color purps. Now I'm looking for other purple accessories to go with my 2021 Honda CRV. I don't think this cover would be be enough for a large SUV arm rest such as a Navigator... But yea, order if you want some color & funk in the ride

Return refund impossible to receive also it’s tacky looking
Color: Black
First off this item said it was fit, but it did not second of all I went to return it and they could only be returned to the original payment method my credit card. My bank is not showing anything. Amazon is zero help trying to say it went back on a gift balance, which I have photo proof that both are incorrect. I tried to reach out to the seller and they were also zero help so I advise one not to buy this because it’s small and cheap looking too you can’t get your refund back.
