Notable Features of the MS 661:
Anti-Vibration System: STIHL's anti-vibration system is a result of meticulous engineering, minimizing vibration levels in handheld outdoor power equipment. This feature significantly reduces operator fatigue and promotes a more comfortable work experience.
Side Access Chain Tensioner: The side-access chain tensioner presents a more user-friendly approach for adjusting the saw chain using a bar wrench, as opposed to the conventional guide bar adjustment screw location.
Decompression Valve: Also known as the 'deco' or 'deco valve,' this valve effectively releases compression within the cylinder to facilitate an easier starting process. During cranking, the decompression valve temporarily alleviates the compression within the combustion chamber, making it easier to pull the starter rope. It is manually opened and automatically closes upon the engine's ignition.
Stihl Elastostart: Exclusive to STIHL, the ElastoStart™ starter handle features a built-in shock absorber that notably reduces the effort required when pulling the starter cord. This design smooths out the sudden peak forces (compression) typically encountered during cranking, providing a more comfortable starting experience.
Adjustable Automatic Oiler: The Adjustable Automatic Oiler grants users the flexibility to fine-tune the lubrication for the guide bar and saw chain to accommodate varying bar lengths and cutting conditions.
Fuel and Caps with Retainers: These handy cap retainers ensure that the caps remain securely attached to the unit, enhancing user convenience and minimizing the risk of misplacement.
HD2 Air Filter: The washable HD2 air filter integrated into this chainsaw boasts an extraordinarily long filter life, effectively reducing maintenance expenses. Its generously sized surface area enables longer intervals between cleanings, ensuring consistently high performance, even when operating in dusty and arid conditions. Overall, the HD2 air filter offers superior engine protection when compared to standard air filters.
