Stihl MS 661 C-M Chainsaw - 30"

Stihl MS 661 C-M Chainsaw - 30"

SKU: MS661-30

Big timber saw for the toughest jobs in forestry. The M-Tronic guarantees optimum engine performance at all times, while its single start position and stop button function mean easy starting. Controlled-delivery high-performance oil pump for conveying high quantities of oil; HD2 filter with very good filter effect, economical 2-MIX engine.

 

The STIHL MS 661 C-M chain saw is equipped with cutting-edge technologies for outstanding performance. Weighing in at just 7.4 kg and with an impressive output of 5.4 kW, it boasts a low-power-to-weight ratio and is the lightest chain saw in its engine displacement class. Because it's not just power that counts when you're harvesting large timber, but also every gram of weight. That makes work easier, even for the most skilled professionals.

 

  • 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.

     

    Carburettor heating (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.

     

    Controlled-delivery oil pump

    Different bar lengths, wood types and sawing techniques require different amounts of oil. The controlled-delivery oil pump allows the user to select just the right amount of oil for the job at hand.

     

    Side-mounted chain tensioning

    Side-mounted chain tensioning makes it easy to tension the chain safely.

     

    HD2 filter

    This air filter keeps even the finest dust away from the engine, ensuring a particularly long service life. Thanks to its special material, the filter can easily be cleaned by washing, for example with STIHL Varioclean and warm water.

     

    Compensator

    This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.

     

    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 reducing 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.

     

    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.

     

    STIHL Ematic System

    Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50 %, depending on the type of wood and the cutting attachment used. This system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a variable-flow or reduced-flow oil pump. As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.

     

    Single-lever master control

    All important functions such as start, choke, throttle and stop are operated via a single lever.

     

    Tool free fuel caps

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