STIHL MS 661 C-M Professional Chainsaw

Description

STIHL MS 661 C-M is the most popular commercial chainsaw worldwide, designed for felling, trimming, and all forestry applications. This rugged all-rounder is equipped with STIHL’s advanced 2-MIX engine technology, delivering less fuel consumption, reduced emissions, and outstanding cutting performance.

Key Features:

1. HD2-Filter for Longevity: The MS 661 C-M boasts a heavy-duty (HD2) air filter system with a radial seal, effectively keeping fine dust particles at bay. Paired with the compensator, this chainsaw can now be used for 20% longer before requiring a filter clean. The washable filter ensures a long service life, offering easy maintenance with STIHL Varioclean and warm water.
2. Decompression Valve for Easy Starts: The decompression valve, part of the easy start-system, reduces compression pressure during starts, making it easier to pull the starter rope. Semi-automatic in operation, it requires manual pressing before starting but closes automatically.
3. STIHL M-Tronic (FT) for Precision: The M-Tronic electronic engine management system enables automatic adjustments to varying fuel grades, altitude, and temperature. Starting the MS 661 C-M is now simpler than ever – just push the start lever to the “on” position and pull.
4. Anti-Vibration System: STIHL’s anti-vibration system dampens oscillations from the engine, significantly reducing vibrations at the handles. This innovative feature minimizes long-term effects on blood vessels in the hands and arms caused by intense vibrations.
5. Compensator for Consistent Power: The carburetor’s compensator prevents the fuel-air mixture from getting richer as the air filter clogs, ensuring a constant fuel/air ratio and consistent engine power. The filter remains effective until a noticeable drop in power occurs.
6. Captive Bar Nuts: Bar nuts held captive in the sprocket cover eliminate the risk of loss during cutting attachment changes, providing added convenience.
7. Controlled-Delivery Oil Pump: Adjust the chain oil output manually for varying conditions, reducing oil consumption by up to 50%. This controlled delivery ensures optimal lubrication for the saw chain and guide bar.
8. QuickStop Chain Brake: Safety is paramount with the QuickStop chain brake, operated via the front hand guard. It brings the saw chain to a halt in fractions of a second, providing protection during handling.
9. Side-Mounted Chain Tensioning: The tensioning screw located on the side of the chainsaw allows effortless retensioning of the saw chain, avoiding contact with the sharp chain.
10. STIHL Ematic-System: The Ematic chain lubrication system offers pinpoint lubrication for saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it maximizes lubrication, reduces wear, and minimizes oil consumption.
11. STIHL ElastoStart: Reduce starting shock with STIHL ElastoStart, which absorbs the compression shock during engine starts, promoting user comfort.
12. Tool-Free Fuel Caps: Special caps on the fuel and oil tanks feature a tool-free design, allowing easy opening and locking for hassle-free operation.
