2020 STIHL Gas Chain Saws For Forestry MS 661 C-M

MS 661 C-M

Professional chain saw

The MS 661 C-M chain saw is equipped with cutting-edge technologies for the best possible performance for the logging and harvesting industries. It boasts a high power-low weight ratio and is the lightest chain saw in its engine displacement class. The extra powerful and efficient delayed stratified scavenging engine allows you to work effectively, thanks to its high cutting performance and low emissions. It features the M-Tronic™ fully electronic engine management system, which uses a microchip to control the engine’s ignition timing and fuel supply, taking into account variables such as temperature, fuel quality and elevation. Take it to the max, with minimum effort. Also available with full wrap or heated handles and carburetor (MS 661 C-M VW R)

Features may include:

Heated carburetor (V)

• By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.

STIHL anti-vibration system

• Precisely calculated buffer zones minimise the transfer of engine and saw chain vibrations to the front and rear handles. The chainsaw therefore runs noticeably smoother. This allows the user to save their strength and work longer.

Reduced-emission engine technology

• 2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

Electrically heated handles (W)

• More comfort in cold weather. The heated handles (W) can be engaged with a switch on the left handle as required.

Pre-separation air filtration system

• STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.

STIHL ElastoStart

• Due to compression pressure, jerky stresses occur when starting internal combustion engines. The damping element in the ElastoStart special starter grip alternately absorbs and releases force according to the compression pattern. The result is smooth, even starting.

Tool free fuel caps

• Special caps to open and close the tank cap quickly, easily and without tools.

Decompression valve

• The decompression valve is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.
