Distinguishing Features of the MS 661 C-M:
Reduced-Emission Engine Technology – Caring for Nature: The STIHL Inc. “Caring for Nature” emblem signifies their commitment to environmentally-conscious powered products, characterized by minimal or zero exhaust emissions. These products adhere to standards of cleanliness surpassing those set by the EPA and CARB for exhaust emissions.
Stihl M-Tronic: The M-Tronic™ feature, denoted as (M), represents an innovative era in Intelligent Engine Management. It eliminates the need for manual adjustments of low and high-speed carburetor screws, effortlessly compensating for issues such as a dirty air filter and variations in elevation and fuel quality. This ensures the engine operates at peak performance at all times.
Decompression Valve: Commonly referred to as the 'deco' or 'deco valve,' this valve acts as a pressure vent in the cylinder, facilitating easier engine starting. It temporarily alleviates compression in the combustion chamber during cranking, thus diminishing the effort required to pull the starter rope. The valve is manually activated and closes automatically upon engine ignition.
Stihl Elastostart: Exclusive to STIHL, the ElastoStart™ starter handle is designed with an embedded shock absorber, markedly reducing the physical strain when pulling the starter cord. This unique feature smooths out the abrupt peak forces (compression) that are usually experienced during the initial cranking stages, ensuring a more comfortable and effortless starting process.
Adjustable Automatic Oiler: The Adjustable Automatic Oiler empowers the user to fine-tune the lubrication of the guide bar and saw chain to accommodate various bar lengths and cutting conditions.
Anti-Vibration System: STIHL's advanced anti-vibration system is engineered to minimize the levels of vibration in handheld outdoor power equipment. This system not only reduces operator fatigue but also enhances overall work comfort.
Side Access Chain Tensioner: The side-mounted chain tensioner introduces a newfound convenience for users to make adjustments to the saw chain. It enables easier fine-tuning with the use of a bar wrench, deviating from the conventional placement of the guide bar adjustment screw.
