MS 661 C-M .404

STIHL MS 661 C-M Chainsaw

Simply the most popular commercial chain saw in the world for felling, trimming and all commercial and forestry applications. The MS 661 C-M is a rugged all-roander equipped with STIHL's environmentally friendly 2-MIX engine technology for less fuel consumption, less emissions and outstanding cutting performance. In addition the MS 661 C-M features a heavy duty (HD2) air filter system with a radial seal which keeps out fine dust particles combined with the compensator the MS 661 C-M can now be used for 20% longer than the MS 660 before a filter clean is required. The MS 661 C-M is fitted with STIHL's M-TRONIC electronic engine management system which enables the saw to automatically adjust to varying fuel grades, changes in altitude and temperature and as there are no manual carburettor adjustments starting this saw is easier than ever before, simply push the start level to the on position and pull. The MS 661 C-M is now the only choice for professionals.

  • HD2-FILTER
    INCREASES SERVICE LIFE. The HD2 filter protects your power tool’s engine against even the finest dust, ensuring a longer service life and reduced wear. The filter made from PET material has up to 70% finer pores than fleece and polyamide filters, and is also oil- and water-repellent. This also makes it easier to clean the filter. When needed, the filter cartridge can be easily replaced without tools.
  • MANUAL DECOMPRESSION
    EFFORTLESS START-UP. The decompression valve makes it easier to start your power tool. When starting, you can allow some of the compressed mixture to escape from the cylinder by opening the valve. This protects the start-up system and reduces the amount of force required on the starter cord.
  • COMBI LEVER WITH STOP FUNCTION
    SIMPLIFIED OPERATION. Only one start position is required on the combi lever. Thanks to the stop function, once the machine is turned off the control lever immediately moves back into the operating position. This allows a warm machine to be restarted immediately.
  • STIHL M-TRONIC
    RELIABLE WORK WITH BEST PERFORMANCE. With the STIHL M-Tronic, you have the best performance from your implement right from the start. The fully electronic engine management regulates the ignition point and fuel metering in every work situation, taking into account external conditions such as temperature, altitude and fuel quality.
  • STIHL ANTI-VIBRATION SYSTEM
    Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.
  • STIHL 2-MIX Engine
    The STIHL 2-MIX engine is both powerful and economical. Separating the exhaust emissions from the unburnt gas minimises scavenging losses, and therefore increases the power output while reducing consumption.<br /><br />The two-stroke engine with STIHL 2-MIX technology saves up to 20% of fuel and reduces emissions by up to 70% compared to STIHL 2-stroke engines of the same performance class without 2-MIX technology.
  • COMPENSATOR
    REDUCED MAINTENANCE. The compensator is a control system in the carburettor, which uses pressure compensation to ensure that engine performance, exhaust gas quality and fuel consumption remain virtually constant over a long period of time, despite increasing contamination of the air filter. You do not need to clean the air filter until there is a noticeable drop in performance. This means that you can work for a long time without maintenance.
  • CAPTIVE NUTS
    PROTECTION AGAINST LOSS The nuts are attached to the sprocket cover in a captive manner. This makes it impossible for the nuts to fall off and get lost when the cover is removed.
  • CONTROLLED-DELIVERY OIL PUMP
    OIL CONSUMPTION BASED ON NEED. The controlled-delivery oil pump reduces your chainsaw’s oil consumption by up to 50%. To use it, simply select the E position. For very long cutting attachments or very dry wood, an additional oil volume can be set by the user.
  • SIDE-MOUNTED CHAIN TENSIONING
    FOR SIMPLE AND SECURE RE-TENSIONING. Side-mounted chain tensioning allows for protected, easy and quick chain tensioning and replacement. The tensioning screw is inserted laterally through the sprocket cover.
  • STIHL EMATIC SYSTEM
    REDUCES OIL CONSUMPTION. The STIHL Ematic system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a controlled-delivery oil pump. It ensures that the chain oil gets to where it is needed for lubrication. This allows you to reduce oil consumption by up to 50%. If you often work in dusty conditions or if you use long guide bars, you can quickly and easily increase the oil quantity at any time with the new oil pump system.
  • TOOL-FREE FUEL CAP FOR OIL AND FUEL TANKS
    QUICK AND EASY TO USE. With tool-free fuel cap, you can open and close oil and fuel tanks in just a few simple steps, thanks to a bayonet closure.
