The mammoth Stihl MS 661 C-M chainsaw is the mother of all M-Tronic saws with a huge 91.1cc engine and a generous 25" bar (Optional in 30" too). Its introduction into the industry has seen it fly to the number one ranking in its class for felling, trimming and all professional contractors and forestry applications. The MS 661 is a strong all-rounder featuring Stihl's innovative 2-Mix technology.

Reducing the amount of fuel consumed and the number of emissions produced. Equipped with an HD2 air filter for longer life span in-between maintenance runs, while also being manufactured with Stihl's M-TRONIC electronic engine management system. This new system allows the saw to automatically adjust to the conditions after a few cuts. Factors taken into account by the saw are varying fuel grades, altitude and temperature so the saw can perform at its optimum capacity all the time. Taking quality and innovation in a saw to the next level. Purchasing this saw may put you in the dog kennel with the missus for the next few weeks but you've just gotta have one, even if you've got no wood to cut!

Priced with 3/8 .063 25" Rollematic Bar
Availble in 3/8 .063 25" ES Light Bar

Features

	Captive Bar Nuts The bar nuts are held captive to the sprocket cover, so you can't lose them when change the bar, chain etc. Although if you loose the sprocket cover this feature won't be much help to you!
	Stihl M-Tronic Technology This innovative technology is one small step for man, and one giant step for mankind! The fully electronic engine management system adjusts ignition timing and fuel metering in all operating models. The saw during the first few cuts will take into consideration conditions such as the altitude, fuel quality and temperature in order to produce the most efficient cut at the time. It also makes manual carby adjustments unnecessary as the electronic start recognition can determine whether the saw is starting from cold or warm meaning there is no choke and just one starting position. The M-Tronic technology can also remember previous conditions so if it is used in the same scenario again it will automatically be at optimal performance from the first cut.
	Stihl 2-Mix Engine The result of this is a saw which is more fuel efficient while running cleaner. This is due to the the advanced stratified charge system that increases the power of the saw at the same time as minimising consumption. Resulting in increased fuel efficiency which is better for your wallet
	Anti-Vibraton System Using a chainsaw always results is significant vibration causing fatigue for the operator. Thats why Stihl's anti-vibration system is an innovative piece of technology that sets it apart from the rest. The vibration system sees the oscillations from the engine dampened reducing the handle vibration.
	Stihl ElastoStart Stihl elastostart reduces the shock caused by the compression of the engine when starting it. The shock is reduced by the users joints and muscles through the spring or rubber element in the starter handle making it more comfortable to start for the operator.
	Decompression Value The decomp valve needs to be pushed down when starting which minimises the compression pressure when you pull it over making it easier to start. The decamp value is semi-automatic meaning that it has to be manually engaged but it will automatically disengage when your saw kicks over.
	Compensator Is the process of the controller in the carby preventing the fuel-air mixture from getting too rich when the air filter gets blocked up. Ensuring the right amount of fuel is delivered to the carby while taking into consideration the amount of air coming through the air filter. This ensures the mixture is constant and in return results in constant engine power.
	Stihl Ematic-System This automatic chain lubrication system ensures that the exact right amount of oil is applied to the chain at the right point at the right time. This precise system means less oil is consumed by the saw and increase the precision of oiling and optimum lubrication. The Ematic system can reduce bar oil consumption up to 50%.
	Side Chain Tensioning On the side of the chainsaw, on the sprocket cover is an easily accessible screw to tighten the chain accordingly.
	Long-Term Air Cleaner System The long life air filter system has a service life of up to five times longer than the previous air filter system. The innovative HD2 filter is manufactured from a water and oil repellent polyethylene filter material. Consisting of up to 70% finer pores than fleece and is substantially easier to clean. Meaning more cutting can be done in between maintenance on your machine.
	Variable-Displacement Oil Pump This feature allows the operator to control the exact amount of chain oil they want for different conditions, allowing the reduction of oil up to 50%.
